Do dogs think humans are their parents?
This is a unique behavior between dogs and humans — dogs seek out eye contact from people, but not their biological dog parents.
"Bonding with owners is much more important for dogs than other pets," said Andics.
Scientists have also looked at the dog-human relationship from the other direction.
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.
