Hey Robin... 🙂 Dog's breath actually should not smell bad. If it does, it means your dog's teeth need to be professionally cleaned, or you need to brush his or her teeth. I KNOW this sounds silly, and can be a bit of a hassle, but you can actually increase your dog's longevity by about five years just by providing him or her with good dental care. What kind of dog do you have? I have a boston terrier and a pomeranian. 🙂
