How do dogs lay down?
Doggy beds and pillows haven't always been around, so wild dogs had to pat down tall grass and underbrush to make a comfortable bed for themselves and their pups.
The easiest way to prepare that night's sleeping area was by walking around in a circle.
The rounding ritual may also have served as a safety precaution.
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.
