I have a year old male Maltese named Tanner (he's so cute, he's asleep on my desk at work right now) however, when I took him to the vet to get neutered in Feberuary, his ALT was sky high, like 350. Naturally, we didn't neuter him, put him on vitamins, that didn't work, changed his diet to Science Diet L/D, that didn't work, then sent him to the vet internist for an ultrasound to see if he had a liver shunt, he didn't. That vet suggested we do a liver biopsy but that still may not tell us what's wrong and Tanner is at risk for anesthesia. I decided against the biopsy since he could die from the anesthesia and I still might not know what's wrong with him. Right now he is asymptomatic. I got some really good info from the DogAward website, what a great place. But I'm wondering what I can expect, how doe these things usually progress. Has anyone had any experience with this?
