I just picked her from the breeder on Fri(4/3) and today is Tues (4/7), she started trying to eat her poop on Sunday. So now I am racing to get the poop before her. I read that it can be something lacking in her diet, which I am currently switching her food to Blue Buffalo, from the breeders food, but she hasn't eaten today at all( she ate it yesterday). When she does poop, it looks OK, from what I have read. What can I do to stop this behavior?
