My pomeranian recently had 5 pups! She didn't start losing her hair until much later. It's been at least 16 weeks since she has had them. I have had her on premium food since I got her. (I did change the brands of food because I heard it was the best kind) This happened pretty rapidly. One day she had a full coat, and within a couple of days it was gone. No bald or dry spots at all. No fleas. Just way less hair. I hear it could be from stress (maybe of not having her pups around anymore) Is there anything I can give her to help her grow her hair back?
