Trichophyton. Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp.
Tardive dyskinesia (TD) is a disorder that results in involuntary, repetitive body movements. This may include grimacing, sticking out the tongue, or smacking the lips. The condition typically develops only after months to years of use. The diagnosis is based on the symptoms after ruling out other potential causes.
Pyoderma literally means “pus in the skin.” It can be caused by infection, inflammation, or cancer and is common in dogs. Most cases of pyoderma are caused by bacterial infections. Most of these are superficial and secondary to a variety of other conditions, such as allergies or parasites.

Osteoarthritis, Arthritis in Dogs. Arthritis is the medical term for inflammation of the joints, while osteoarthritis is the term referring to a form of chronic joint inflammation caused by deterioration of joint cartilage. Older dogs are at the highest risk.
Gastroenteritis is a medical term referring to inflammation of the gastrointestinal tract, usually the stomach and intestines. It can be caused by infection with bacteria, viruses, parasites, or reactions to medications or new foods. It often involves abdominal discomfort or pain, diarrhea and/or vomiting.
Specific vestibular system problems. Vestibular dysfunction is most commonly caused by head injury, aging, and viral infection. Other illnesses, as well as genetic and environmental factors, may also cause or contribute to vestibular disorders.
A balance disorder may be caused by viral or bacterial infections in the ear, a head injury, or blood circulation disorders that affect the inner ear or brain. Many people experience problems with their sense of balance as they get older. Balance problems and dizziness also can result from taking certain medications.
Most cancer pain is caused by the tumour pressing on bones, nerves or other organs in the body. Sometimes pain is due to your cancer treatment. For example, some chemotherapy drugs can cause numbness and tingling in your hands and feet. You could have the general aches and pains that everyone gets from time to time.
Gonzo operates on my toe! Good Grief! Paronychia - Rats!
Dog zoomies tend to hit puppies and young dogs more frequently than older dogs, but zoomies are a great way for dogs of any age to release pent-up energy. Dogs get the zoomies for a variety of reasons — when they are highly excited or aroused or after watching another dog engage in high-energy play.
Canine distemper is caused by a single-stranded RNA virus of the family Paramyxoviridae (the same family of the viruses that causes measles, mumps, and bronchiolitis in humans). The disease is highly contagious via inhalation.
Causes of these conditions may include genetic mutations and abnormal chromosomes. Researchers also believe that environmental factors, such as exposure to X-rays, chemicals, drugs, pesticides, toxins, radiation, or viruses, increase the risk of anophthalmia and microphthalmia, but research is not conclusive.
There are many causes of paraplegia or hind end paralysis in dogs. Far and away, the most common cause is intervertebral disc disease (aka, slipped disc or herniated disc). Dachshunds are the “poster dogs” for this disease. For some dogs though, surgery is ineffective.
Hematuria is a condition which causes blood to fall into the urine, and which may indicate a serious underlying disease process. Familial hematuria (a condition in which blood in the urine runs in certain families of animals) is usually implicated in young dogs, while cancer is the usual cause in older dogs.
Benign prostatic hyperplasia (BPH) — also called prostate gland enlargement — is a common condition as men get older. An enlarged prostate gland can cause uncomfortable urinary symptoms, such as blocking the flow of urine out of the bladder. It can also cause bladder, urinary tract or kidney problems.
It's not a disease that occurs by itself; rather, DIC is a complication that is seen as a result of secondary underlying causes in the body. With DIC, the body is unable to clot normally. There are several primary causes that can predispose the body to this blood clotting disorder: Cancer (e.g., hemangiosarcoma, etc.)
Loa loa filariasis is a skin and eye disease caused by the nematode worm Loa loa. Humans contract this disease through the bite of a deer fly or mango fly (Chrysops spp), the vectors for Loa loa. The disease can cause red itchy swellings below the skin called "Calabar swellings".
In older individuals, a sinus arrhythmia can occur as a result of heart disease or another heart condition. Damage to the sinus node can prevent the electrical signals from leaving the node and producing a steady, normal heartbeat.
Hepatitis and cirrhosis of the liver can cause a reduction in bile salt which your body needs to properly digest foods. Gallstones can also lead to yellow stool or diarrhea, as they reduce the amount of bile that reaches your intestines. Typically, pain accompanies these disorders.
Liver and gallbladder disorders. Cirrhosis of the liver and hepatitis reduce or eliminate bile salts that help the body digest food and absorb nutrients. Gallstones or sludge in the gallbladder reduce the amount of bile that reaches your intestines. Not only may this cause pain, but it can also turn your stool yellow.
The timing of the nausea or vomiting can indicate the cause. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.
A dog may vomit simply because he's eaten something disagreeable or gobbled down too much food, too fast. But vomiting can also indicate something far more serious-your dog may have swallowed a toxic substance, or may be suffering from a condition that requires immediate medical attention.
Paw knuckling in dogs can be caused by many things. A red and irritated paw caused by an allergy, bug bite, thorn, laceration or exposure to hot pavement or a toxic chemical (ice melt) can cause a dog to not want to put pressure on their paw so they walk with it turned over.
In the developed world Campylobacter jejuni is the primary cause of bacterial gastroenteritis, with half of these cases associated with exposure to poultry. In children, bacteria are the cause in about 15% of cases, with the most common types being Escherichia coli, Salmonella, Shigella, and Campylobacter species.
Regurgitation of sour-tasting or bitter-tasting material can result from acid coming up from the stomach. Regurgitation of tasteless fluid containing mucus or undigested food can result from a narrowing (stricture) or a blockage of the esophagus or from an abnormal pouch in the esophagus called a Zenker diverticulum.
There are two good reasons for neutering a dog with cryptorchidism. The first is to remove the genetic defect from the breed line. Cryptorchid dogs should never be bred. Second, dogs with a retained testicle are more likely to develop a testicular tumor (cancer) in the retained testicle.
If your dog is doing more swallowing than licking, esophagitis may prove the culprit. That's inflammation of the esophagus, and it's often caused by acid reflux. Other esophagitis indicators include poor appetite, increased mouth secretions, and a reluctance to move. Dogs with esophagitis may often regurgitate food.
Infectious canine hepatitis (ICH) is an acute liver infection in dogs caused by Canine mastadenovirus A, formerly called Canine adenovirus 1 (CAV-1). CAV-1 also causes disease in wolves, coyotes, and bears, and encephalitis in foxes. Death can occur secondary to this or the liver disease.
Aggressive Puppy - The Causes of Puppy Aggression. Truly aggressive puppies display behaviors such as biting, snapping, and growling in situations they should not - like normal petting and handling from people. All puppies will bite and growl in play, but not with the the intent to cause harm to another dog or a person
However, cellulitis most commonly occurs on the skin of the lower leg. Bug bites, such as those from mosquitoes, bees, and ants, can all break the skin. Bacteria that live on the surface of your skin can then enter those small puncture points and develop into an infection.
Changes in surroundings, such as a new house, school, or day care situation, can trigger separation anxiety disorder. Stress. Stressful situations like switching schools, divorce, or the loss of a loved one—including a pet—can trigger separation anxiety problems. An over-protective parent.
Trauma is a common reason for dogs and cats to be brought into one of our Emergency hospitals for evaluation and treatment. There are many causes for these types of injuries such as falls, gunshot wounds, being hit by a moving object such as a car or boat or injuries caused by blunt objects.
Gastroenteritis refers to inflammation of the gastrointestinal tract, meaning the stomach and the intestines. It can be caused by infection with bacteria, viruses, parasites, medications, or even new foods. The condition often causes abdominal pain, diarrhea, vomiting, and/or other clinical signs.
Salmonella may be caused by uncooked meat or seafood. Salmonella bacteria live in the intestines of birds, animals, and humans. Most human infections are caused by eating food or drinking water that has been contaminated by feces.
Demodectic mange is caused by Demodex canis, a parasitic mite that lives in the hair follicles of dogs. Demodectic mange most often occurs when a dog has an immature immune system, allowing the number of skin mites to increase rapidly.
This acidic food causes an acidic environment in the babies' digestive system which results in the child excreting acidic urine. The child may also produce stools that burn the skin and create local skin irritations as well as internal inflammations.
Research suggests that depression doesn't spring from simply having too much or too little of certain brain chemicals. Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, stressful life events, medications, and medical problems.
Chafing refers to the irritation of skin caused by repetitive friction, usually generated through skin to skin contact of multiple body parts. Chafing is usually contracted in the inner thighs and inner glutes; armpits and nipples can also develop chafing although it is less common.
Bloating is when your belly feels swollen after eating (1). It is usually caused by excess gas production or disturbances in the movement of the muscles of the digestive system (2). Bloating can often cause pain, discomfort and a "stuffed" feeling. It can also make your stomach look bigger (3).
Eye boogers refer to a buildup of mucus in the eyes. During the day, each time a person blinks, the eyes flush away the secretions of rheum they have produced. Since the eyes produce this mucus in such small quantities, most people never notice it. At night, when a person does not blink, the mucus can build up.
Snow nose affects white dogs and lighter colored dogs most often, but other dogs may also lose nose pigment. It occurs most often during winter months, causing some people to theorize that the condition is related to sunlight. His brown nose is genetic and not related to sunlight or other changes in his environment.
The patient typically recognizes a problem with excessive "foamy mucus" but does not understand its origin. Infections and obstruction are the most common oropharyngeal causes. Increased salivary flow occurs as a typically subtle manifestation of gastroesophageal reflux disease.
Pyometra is a secondary infection that occurs as a result of hormonal changes in the female's reproductive tract. During estrus ("heat"), white blood cells, which normally protect against infection, are inhibited from entering the uterus.
When our brains feel happy, endorphins are produced and neuronal signals are transmitted to your facial muscles to trigger a smile. This is the start of the positive feedback loop of happiness. In short, when our brain feels happy, we smile; when we smile, our brain feels happier.
Eight things cause about 90% of food allergy reactions: Milk (mostly in children) Eggs. Peanuts. Tree nuts, like walnuts, almonds, pine nuts, brazil nuts, and pecans. Soy. Wheat and other grains with gluten, including barley, rye, and oats. Fish (mostly in adults) Shellfish (mostly in adults)
There are many causes of cleft lip and palate. Problems with genes passed down from 1 or both parents, drugs, viruses, or other toxins can all cause these birth defects. Cleft lip and palate may occur along with other syndromes or birth defects.
Tetanus Bacillus Infection in Dogs. Tetanus is an occasional disease in dogs, the result of infection with a bacterium called Clostridium tetani. These potent toxins bind to nerve cells in the body and generate symptoms that are characteristic of this disease, such as muscle spasms and stiffening of the limbs.
A canine's tail is an extension of itself and when dogs are happy they tend to show their happiness with a wagging tail. Dogs that wag their tails too vigorously against hard objects may cause the tail to split open and bleed, this condition is called happy tail syndrome, and can become chronic.
Unsourced material may be challenged and removed. Demodicosis, also called demodectic mange or red mange, is caused by a sensitivity to and overpopulation of Demodex canis as the host's immune system is unable to keep the mites under control. Demodex is a genus of mite in the family Demodicidae.
Gastroenteritis can also be caused by a virus, such as norovirus. Norovirus is highly contagious and most common in the winter months. Chemotherapy drugs, morphine, and alcohol are all classed as toxins, and they can all cause nausea and vomiting. In some cases, this may be projectile vomiting.
Q. What are the causes and symptoms of DCM? A. It's often linked to a deficiency in the amino acid taurine. Symptoms include enlarged heart, decreased energy, cough, difficulty breathing and even episodes of collapse. If you suspect that your dog is affected, consult your veterinarian immediately.
Causes. A number of causes may account for a hematosalpinx, by far the most common being a tubal pregnancy. Blood may also escape into the peritoneal cavity leading to a hemoperitoneum. A hematosalpinx can also be associated with endometriosis or tubal carcinoma.
Most common causes for adnexal masses in premenopausal women are follicular cysts and corpus luteum cysts. Abscesses can form as a complication of pelvic inflammatory disease. Other masses include endometriomas, polycystic ovaries, and benign neoplasms.
Selective eating in children could be attributed to bad experiences with certain foods, leading to anxiety developing when being forced to eat the food, or try new foods. Some children may also have heightened senses that cause the tastes and textures of certain foods to become overwhelming.
Causes of Friction. Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
If the muscles don't join together completely in the midline of the abdominal wall, an umbilical hernia may appear at birth or later in life. In adults, too much abdominal pressure contributes to umbilical hernias. Causes of increased pressure in the abdomen include: Obesity.
This rids the body of stomach acid, which can make body fluids more basic. Acidic urine can also create an environment where kidney stones can form. If a person has low urine pH, meaning that it is more acidic, it might indicate a medical condition such as: diabetic ketoacidosis, which is a complication of diabetes.
Anxiety, stress, and depression are some of the most common causes of chronic insomnia. Having difficulty sleeping can also make anxiety, stress, and depression symptoms worse. Other common emotional and psychological causes include anger, worry, grief, bipolar disorder, and trauma.
Hydrocephalus is a condition where cerebrospinal fluid builds up in a dog's skull, putting pressure on the brain. It is sometimes referred to as “water on the brain.” It is often congenital, meaning it is present at birth, and certain breeds are predisposed to the condition, especially small dog breeds.
The causes of vomiting differ according to age. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.
Jowls can be caused by a combination of factors: saggy facial skin, droopy facial fat and loss of facial volume. One of the earliest signs of facial aging is the development of jowls. As we age, our facial skin loses elasticity and we begin to see a fold of skin along the jawline, commonly called the jowl.
Horner syndrome (Horner's syndrome or oculosympathetic paresis) results from an interruption of the sympathetic nerve supply to the eye and is characterized by the classic triad of miosis (ie, constricted pupil), partial ptosis, and loss of hemifacial sweating (ie, anhidrosis).
An odor, or odour, is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor.
With secondary AIHA, the surface of the red blood cells becomes altered by an underlying disease process or a toxin. The dog's immune system then recognizes the altered red blood cells as 'foreign' invaders that must be destroyed. In dogs, neoplasia or cancer appears to be the most common cause of secondary AIHA.
Another cause can be vibration caused by poor machine mounting or loose foundation plates. The spacing between the chatter marks will indicate whether it is the contact roller or a defective abrasive belt. Splice marks are similar to chatter marks but are caused by a poor belt splice.
Causes. Boar taint is caused by the accumulation of two compounds – androstenone and skatole – in the fat of male pigs. As a result, skatole accumulates in the fat of male pigs as they mature.
Pannus is an abnormal tissue growth caused by thickening of the synovium. RA causes the body to release proteins called cytokines. Cytokines cause new blood vessels to develop in the synovium, causing the growth of extra tissues. This tissue then eventually forms pannus.
There are three main reasons why older people are more likely to have a fall. These are: chronic health conditions, such as heart disease, dementia and low blood pressure (hypotension), which can cause dizziness. impairments, such as poor vision or muscle weakness.
Other causes of hives are: Infections, including colds and infections caused by some bacteria or fungi. Some illnesses, including a type of vasculitis, lupus, and thyroid disease. Exposure to sun (solar urticaria), heat, cold, or water.
The presence of air bubbles in the fluid can lead to excessive oxidation, cavitation, the reduction of lubricating properties of the oil and hydraulic system failure. The causes of foaming are many. The most common include: Cross contamination of the fluid with the wrong lubricant.
What are the causes of bubble guts? If a person has excess amounts of fluid in the gut, it can lead to a bubbling sound, excess gas that accumulates in the intestines, certain diseases, diarrhea, swallowing excess air, eating certain foods, some medications, and even hormonal changes can cause bubble guts.
After inhalation, it can cause long term scarring of lung tissue as well as induce cancer and lung disease. Fine dust particles are small enough to penetrate deep into the lung alveoli. Ultrafine dust particles are so small that after they also penetrate into the blood or lymphatic system through the lungs.
Causes. The most common cause of melena is peptic ulcer disease. However, any bleeding within the upper gastrointestinal tract or the ascending colon can lead to melena.
When your dog or cat experiences a fearful situation (stimulus), anxiety is increased and a deep seated, lasting memory of the experience is buried in your pet's brain. In many cases, it may not be caused by the stimulus itself, but signs or actions that precede it that initiate the fear response.
There are many common triggers for anger, such as losing your patience, feeling as if your opinion or efforts aren't appreciated, and injustice. Other causes of anger include memories of traumatic or enraging events and worrying about personal problems. Your personal history feeds your reactions to anger, too.
This image shows pityriasis versicolor (left) and folliculitis (right); two skin diseases caused by Malassezia yeasts. Most of the problems caused by Malassezia yeasts are skin diseases. Some of them, like dandruff and atopic eczema in humans or external ear infections in dogs, are very common.
Cytolysis occurs when a cell bursts due to an osmotic imbalance that has caused excess water to move into the cell. Cytolysis can be prevented by several different mechanisms, including the contractile vacuole that exists in some paramecia, which rapidly pump water out of the cell.
Sometimes, heavy weight on soft soil can result in collapse of ground, resulting in a sinkhole. Sinkholes can also form when the land surface is changed. Areas that have a bedrock made of limestone, salt deposits or carbonate rock are most susceptible to erosion and the formation of such holes.
Dog acne is benign and more common in dogs with short fur; it may be caused by bacterial infections or trauma to the skin. Canine acne is caused by inflammation of the skin of the muzzle and the lips. This may sometimes be due to allergies, hormones, poor hygiene or bacterial infections.
Puppy strangles, or juvenile cellulitis, is a nodular and pustular skin disorder that affects puppies. The cause of this condition is unknown, but there are breeds that have been shown to be predisposed to it, including golden retrievers, dachshunds, and Gordon setters.
Dust, perfumes, carpet powders, pollen and other common inhaled irritants can cause sneezing in dogs and cats. Snorting: 1. Indeed, any disease that causes the pet sufficient irritation to require the clearing of the nasal passages can result in snorting.
Mushy Stool - Type 6. This form of stool has passed through the colon quickly, due to stress or a dramatic change in diet or activity level. When the body is under stress or not used to a healthy diet and lifestyle, it can push the poop through the intestines faster than intended.
Infestation by the mite Sarcoptes scabiei var. Some conditions are more prevalent in patients with lower socioeconomic status, such as malnutrition, vitamin deficiency, and parasite infection.11 Both scabies and anemia are more common in this population.
Inbreeding results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
Here are some reasons why dogs bark: Territorial/Protective: When a person or an animal comes into an area your dog considers his territory, that often triggers excessive barking. As the threat gets closer, the barking often gets louder. Your dog will look alert and even aggressive during this type of barking.
In some cases, an increase in appetite can be a sign of an abnormal condition, such as some endocrinologic conditions, including diabetes, hyperthyroidism, and Graves' disease. Increased appetite may also be seen in certain emotional or psychiatric conditions, as well as a response to stress, anxiety, or depression.
Genetics, lack of proper socialization, or a combination of the two can cause reactivity, and fear is typically the driving force. Reactive dogs may have certain triggers, such as men with beards or hats, small children, or situations when the dog feels trapped by being on a leash.
Causes of constipation. Constipation usually occurs when stools remain in the colon (large intestine) for too long, and the colon absorbs too much water from the stools, causing them to become hard and dry.
Causes. Gangrene is caused by a critically insufficient blood supply (e.g., peripheral vascular disease) or infection. It is associated with diabetes and long-term tobacco smoking.
And it classifies red meat as a probable carcinogen, something that probably causes cancer. Processed meat includes hot dogs, ham, bacon, sausage, and some deli meats. They found that eating 50 grams of processed meat every day increased the risk of colorectal cancer by 18%.
Aggressive behavior can cause physical or emotional harm to others. It may range from verbal abuse to physical abuse. Aggressive behavior violates social boundaries. It can lead to breakdowns in your relationships.
Most cases of chronic flatulence are caused by a diet that is poorly digested by the dog. These poorly digestible diets cause excessive fermentation in the colon and subsequent gas formation. Soybeans, peas, beans, milk products, high-fat diets and spicy foods are all commonly associated with flatulence in dogs.
Vestibular dysfunction is most commonly caused by head injury, aging, and viral infection. Causes of dizziness related to vestibular system dysfunction are listed below. Disequilibrium: unsteadiness, imbalance, or loss of equilibrium; often accompanied by spatial disorientation.
In most cases, dogs suffering from anxiety will develop behavioral issues or bodily reactions to a particular stimulus that is causing their panic and anxiety. The most common form of anxiety is separation anxiety in dogs, which can occur when a dog is left alone for any period of time.
Frequent hunger may be a symptom of disease. Hyperthyroidism, a condition characterized by an overactive thyroid, is also associated with increased hunger. This is because it causes the excess production of thyroid hormones, which are known to promote appetite (77, 78).
Puppy mill breeding dogs are often given hormones and steroids to try and increase the number of puppies they produce. These drugs can cause extreme pain and serious side effects – all in an attempt to increase the number of puppies for profit.
Meridional aniseikonia occurs when these refractive differences only occur in one meridian (see astigmatism). Refractive surgery can cause aniseikonia in much the same way that it is caused by glasses and contacts. One cause of significant anisometropia and subsequent aniseikonia has been aphakia.
A cause of long-term hiccups is damage to or irritation of the vagus nerves or phrenic nerves, which serve the diaphragm muscle. Factors that may cause damage or irritation to these nerves include: A hair or something else in your ear touching your eardrum.
Parvo in puppies is caused by the canine parvovirus. This virus is highly contagious and spreads through direct contact with an infected dog or by indirect contact with a contaminated object. Your puppy is exposed to the parvovirus every time he sniffs, licks, or consumes infected feces.
There are two broad categories of stroke: those caused by a blockage of blood flow and those caused by bleeding into the brain. A blockage of a blood vessel in the brain or neck, called an ischemic stroke, is the most frequent cause of stroke and is responsible for about 80 percent of strokes.
This discoloration is caused by a chemical called porphyrin. Porphyrins are excreted primarily through bile and the intestinal tract, but in dogs a significant amount of porphyrin is excreted through tears, saliva and also urine. One of the best-known porphyrins is heme, the pigment in red blood cells.
