You aren't a bad mom! You got your pup to a vet immediately.

There is a lot of questionable information online about diet. It's hard to sift through all of it and know what is correct and what isn't. Now you know though - high fat and sometimes high protein diets can trigger a pancreatitis in dogs, esp. breeds prone to it (which includes Yorkies). Be very strict with diet from here on out (listen to the vet or a board certified veterinary nutritionist) and there is a good chance all will be fine.
