Liver shunt is genetic so if your dog had it, then it needs surgery or medical management (if it's Microscopic shunting). As for pancreatitis, there are many Yorkies who seem to be prone. For this reason, I keep the fat pretty moderate in my own younger dogs to prevent it. Most is one trigger, but it's not the only one and there seems to be many factors that can set a dog off. Most recently, my 14.5 year old female Yorkie who has never had an issue with fat or pancreatitis had an elderly-onset attack. Quick and aggressive treatment avoided a hospital stay and she recovered. It was triggered by a higher fat food than she was used too, but it was not a "high fat" food. Here on YT we have seen pancreatitis develop in dogs fed dog food, home cooked food, and raw food.

Just pick a more mainstream formulation of food and don't swing too far to an extreme is the best suggestion I can have. Enjoy your pup, try not to worry about every last thing that could happen or you'll drive yourself crazy. I'm talking to myself too!
