Are dogs supposed to have wet noses?
Dogs have wet noses because some of their tear glands empty into their noses.
Just because the nose is dry does not mean there is something wrong with the tear gland.
If your dog's dry nose is not inflamed or infected, he should be fine, especially if he is eating and playing normally!
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.
