Ali I wonder if your girl and Theta's girl are related??? Might be a good person to meet and offer another person to chat with and brain storm in person. Theta, where did you get your pup from and what has the breeder said?? Any hereditary issues she forgot to mention?? Any other pups with similar issues?? Good luck. There will be answers and perhaps it may be as simple as a food allergy, read some of the food comments and try raw or at least grain free, I think it might help
