[abi's mom]

This is something I find very hard to talk about to anyone, but I've caught abi eating her own poop. I started giving her deter tablets 2 weeks ago, one to two everyday. I thought that did the trick, but today I caught her again, and it just makes me so sick. She is so perfect in everyway, I just don't understand why she does this. We pick it up right away if we are home, she is very good about going on the paper, she is 4 months old. I tell her no in a firm voice when I am getting a napkin to pick it up, but sometimes she is just too fast. Please help with any suggestions, the vet told me she will probably grow out of it. Thanks
