Bad breath and food
The food can definitely be a factor on dogs' breath. We have a very small "pomchi" (half pom, half chiuahua). Her breath, especially for such a small dog is absolutely HORRIBLE.
Recently we left our dog with our father in law for a week. Unlike us, he doesn't put his cat's food up where the dog can't get it. Our dog ended up eating cat food for the whole week.
when we went to pick her up her breath was no longer bad. We brought her home, she got back on her regular dog food diet (and no we don't buy cheap generic food or anything) and within a day her breath is bad again.
Dog dental chews etc don't help her breath at all, and I know its unhealthy for dogs to eat cat food, so i have been looking all over trying to find out what I can feed our little dog that won't make her breath smell so bad.
