could be food or could not
how was your dog eating on prior food any issues on that ? What is protein count on new food vs old and what is fat content on new food vs old. Could be hypoglycemia or could not
. Usually they do not vomit or have diarhea with hypoglycemia though so makes me think this is something else in combo. HOw much does your baby weigh? Is your baby drinking alot of water as water is more important than food when stomach is upset but if you have a tiny one i would get to vet to have him checked out .
liver shunt runs in this breed and your baby is young and liver shunt signs are spaced out after eating, vomitting, seizures, picky eater, head pressing, etc - have you seen any of these signs.
Hypoglycemia and liver shunt go hand and hand as well
A yorkie is 38% more likely than any other breed to have liver shunt so you may want to have blood work and bile acids on this pup just to make sure the liver is functioning properly. Our vet thinks all yorkies and maltese should have pre and post bile acids to test liver function since it runs so high in the breed
