Why do beagles like to burrow?
Small-prey hunters, like terriers and Dachshunds, tend to show their heritage of flushing out small animals from their tunnels by burrowing in blankets.
According to some pet experts, dogs are "denning" animals: It is a dog's instinct to sleep or relax in a small and protected space to feel warm and safe.
Dogs also "express" their anal sacs when they are scared, which is perfectly normal, if a bit odorous.
Anal gland secretions have a distinct smell that many people describe as fishy.
If your dog smells like fish, chances are there may be something going on with her anal glands.
Individual dogs also have specific spots where they like to be petted; common areas are the base of the tail, under the chin or on the back of the neck where the collar hits.
Most dogs dislike being touched on top of the head and on the muzzle, ears, legs, paws and tail.
Most lumps are fatty tumors, though.
These are benign, meaning not cancerous.
Fewer than half of lumps and bumps you find on a dog are malignant, or cancerous.
Still, they can look the same from the outside, so it's hard to tell.
That is because it is in their nature to sleep in a pile on top of each other and it's when they feel most secure and comfortable - snuggled up against their littermates.
A recent survey found that as many as 50 percent of dog owners let their dogs sleep on the bed.
This may indicate that a dislike for having the paws touched is a doggie instinct understood amongst all canines.
This natural sensitivity wouldn't need addressing if dogs could do their own pedicures.
But in order to keep your dog orthopedically healthy, he or she will need the nails trimmed regularly.
Dogs love belly rubs simply because they feel good.
It also sets off a specific reaction in their brain that responds to the stimulation of hair follicles.
When your dog rolls over on their back and offers you their belly it's a sign that your dog trusts you, not just a sign of submission.
