I have a miniature toy poodle who up to a week ago was a great eater. All of a sudden she is not eating. I have tried numerous brands of dog food both soft and hard. She doesn't even eat her usual favorite. I don't think there is a medical problem because she will eat people food (meat). She has not had a whole lot of exposure to people food because she has always been a good eater. She is 4 years old, and I am worried. She will drink water OK and seems to be herself. She will walk up to the dish, sniff it and walk away. Please help, I need advice on what to offer her to get her to eat the dog food. She is losing weight.
