Are dogs noses better than humans?
For one thing, they possess up to 300 million olfactory receptors in their noses, compared to about six million in us.
And the part of a dog's brain that is devoted to analyzing smells is, proportionally speaking, 40 times greater than ours.
Dogs' noses also function quite differently than our own.
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.
