I was referring to the breeder saying your pup doesn't have a shunt. They should know if it's present in their lines, but they definitely can't say this pup is shunt free. I would not be worried about their thoughts on this vet trying to make money, etc., etc. That is not a sound opinion from the breeder.

If the liver enzymes are off substantially, then there likely is an issue because liver problems are common in Yorkies. Doesn't necessarily mean it's a shunt or that anything needs to be repaired - just that testing is needed as soon as possible.

My Yorkie does have a liver issue, but not anything that looks like hypoglycemia. At first, hypo and LS/MVD can be hard to distinguish. However, labs are usually very telling, esp. bile acids testing (which your vet will need to do asap).

Not knowing what values are up, it is hard to say even what might be going on. But even if it is a shunt, that definitely doesn't mean your puppy can't live a long and happy life. Medically and/or surgically managed dogs (that are managed correctly) tend to do very well.
