Dixie is absolutely adorable! I would recommend taking her to a veterinarian. It is very concerning that she is barely eating and is not as active as a puppy should be. I have seen very calm puppies but this could also be due to a virus of some sort and she may need medical treatment. Thank you for using Petco Pet Education Center, formerly Petcoach.
