Can dogs detect sadness?
Do dogs understand when their owners are sad? Plenty of pet owners are comforted by a pair of puppy-dog eyes or a swipe of the tongue when their dog catches them crying.
Now, new research suggests that dogs really do respond uniquely to tears.
But whether pets have empathy for human pain is less clear.
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.
