In Wilmington DE (a little far drive) there is a small business called Happy Dog, Healthy Dog where a holistically-trained woman named Diane meets with your dog and analyzes his/her nutritional needs. My dog was so sick she was almost put to sleep, but working with Diane has turned her around 100% worth a shot if you are frustrated. Costs $65 for a consultation, but if you have a problem with your animal that a vet can't fix, Diane might have insight. Definately worth the time, and cheaper than most vet tests.
