Ours is a very picky eater, but sometimes she just can't get enough. She will eat her breakfast and want more of anything! The next day she won't eat one of her meals. Some days she begs all day long. I never know how to handle this. Over Christmas our daughter brought her two larger dogs, and Sophie didn't get much to eat (we had to move her food so the other dogs wouldn't get it, and she was also nervous). So, after they left, she wanted to eat constantly for the next week! It seems we are always having some feeding issue or other.
