I would contact Susan Davis
Holistic Veterinarian Pet Nutritionist Holistic Pet Care. She's a Holisic Nutritionist on here that I highly reccommend. I have been having similar problems with Bailey recently and $312 later from the vet, poor little guy was diagnosed with Pancreatitis. I'd rather know, than keep going around in circles and not know what is wrong with him. I tried the bland diet on and off for 3 weeks and he was still having diarrhea on it. There have been quite a few members that suggested and used/use Susan. She's great and has gotten Bailey back to normal. He feels GREAT! Like you, I will do anything cost wise to make sure my baby is feeling better. In 2005 when Bailey was sick the first time, I went out and purchased Pet Insurance for Bailey. Good luck
