That ALT is way too high. I would not be surprised if something is going on with her liver. When an ALT in a Yorkie is that high, a bile acids test should be done. It could be something like asymptomatic MVD. Anesthetic protocol and pain medications vary for liver compromised dogs, so the vet really should've waited on surgery and did a bile acids test when seeing that number (in my opinion). With an ALT 200 points above the highest it should be and no bile acids test being done, I would not give her any NSAIDs (Rimadyl) but again I'm not a vet and that is my opinion.
That is the poing of preop blood work (to detect problems and do further testing if it is off so surgery is as safe as possible). Why would he do it if he was going to ignore it? I guess I'd wonder why he didn't tell you about the high ALT.
