We have been feeding our puppy Chicken Soup for the Large Breed Puppy's Soul, and now that she's 14 months we're switching her to adult food. Should dobies get large breed food or regular? I was also wondering why she's had fish breath. We haven't changed her food, or given her anything new. She's been on the same food for almost a year, and isn't on any supplements or anything. The only thing different going on is that she was going into heat, but she smelled fishy before the bleeding cycle began. Now it's been 3 weeks and she's over the bleeding, and her breath isn't fishy anymore. Could it really have been related to being in heat? What would cause that?
