My 6 Week Old Puppy Isn't EatingI have a 6 week old puppy. His name is Coffee; he is a Pit Bull mixed with Chihuahua. I just got him yesterday and they said he was 6 weeks old. They said he eats hard dog food (a puppy one), but he isn't eating. I've tried milk, hard puppy food, and soft. He isn't eating anything.
