So I just took Phoebe (7 month Chihuahua) in for her pre-spay bloodwork. The vet called today and said everything looked normal except her liver AST. She said a normal count is around 120 and hers is 159. She wasn't too concerned and said they were still comfortable to proceed with the spay, but should follow-up with more bloodwork in a few months...."If its still high then we will have to explore it further"....what does this mean? What could it be?

There have been no changes in her mood, energy, eating habits (although if you read my past posts this has been an ongoing issue).

Has anyone else experienced this? Any ideas what it could be?
