I've heard of this, but I would NEVER, ever do that without getting a 2nd opinion from a specialist. I would take him to see an internist, perhaps at a teaching hospital. I would do that as soon as possible. You can get a referral from your vet for an internist. Sending prayers to you and your baby!

Pancreatis - what worked for me
 

Hi there,

My Yorkie Whiskey who died at 15 was diagnosed with Pancreatitis at 8 years old. His little body was just not processing the fat, there was a layer of it in his blood when they did a blood pull. It looked really grim. He was overweight and frankly fat (almost 12 lbs!). I switched him from regular, high quality kibble to raw food. I took him to the vet a month later for a check up and he was down to 8.5 lbs. His bloodwork came back crystal clear, and his vet (who was awesome) almost fainted. She was just delighted.

He was energetic like never before, and a happier healthier dog for the rest of his years. He lived til 15 and died from cancer of the spleen. Poor little guy.

Anyway - I highly recommend raw food. Now, for my other yorkies - I get raw food from the pet store. In the 90's it was Steve's Raw Food from Whole Foods. Im not sure that exists anymore. Good luck with your baby. Ill keep him in my good thoughts. And seriously - try raw food.

My 3 lb yorkie had hge last winter (twice within a month) ten I had about four months of constant nightly vomiting. I switched her food four times and finally I have her on canine caviar which the fat and protein content scare me a little. I've heard they recommend giving low fat and protein food to dogs with stomach issues. The protein is mostly meat though so it makes me feel a little better. I got her off of grains and she's on a single meat source which helped. I took her off all meds in June and she was fine. But now she gets horrible upset stomacs if she eat her bowel movements. She's so tiny that she can't hold it long enough until I get home and will go on her puppy pad but then eat it. I'm going to start putting her back on Pepcid. I would like to give it twice a day since it usually doesn't seem to last too long and cerenia seems to help. Im going to keep a couple boxes of that in the house. I've heard it can be used as an anti inflammatory as well as anti vomiting and pain medication. When all this started she stayed over night in the er, had exploratory surgery, multiple X-rays and tests and never found anything. I think food change and probiotics and digestive enzymes have really helped. Now if I can get her to stop eating poop!

my firlfriends dog who has pancreatitis has eaten solid gold low fat food holistique blend for years 6% fat but it is fish based, hope he is better soon

The Vet switched Max to a Vegetarian dog food. He loves it! and hasn't had any issues since.
