Can dogs just get sick?
If a puppy or dog with kennel cough develops more serious symptoms, such as fever, nasal discharge, loss of appetite, lethargy, or a productive cough, it may be getting pneumonia.
Owners should also tell a vet about persistent sneezing or discharge from the eyes, ears or nose.
Many believe it's instinctual behavior, harkening back to the days when your dog's wild ancestors would mask their scent to help them sneak up on their prey.
Wolves, for example, have been observed rolling in animal carcasses or the droppings of plant-eating animals, to cover up their own smell during the hunt.
Safe: Some Vegetables.
Your dog can have a healthy snack of carrot sticks, green beans, cucumber slices, or zucchini slices.
Even a plain baked potato is OK.
Don't let your dog eat any raw potatoes or any potato plants from your pantry or garden.
