It's not really a health question. More a vent than anything, although I'd appreciate advice from anyone who's dealt with similar situations.
My Cassius (he's the nose in my avatar pic, almost 13 year-old Giant Schnauzer/Great Pyrenees) had been off his food for a few days, and then was throwing up everything he did try to eat, so I took him to the vet. I was expecting some kind of GI issue and worried about a blockage. X-ray came back clean, no sign of anything amiss, but his bloodwork showed very elevated liver enzymes. Nothing else weird in the bloodwork. (I could go look on the paperwork exactly which ones, but honestly, I'm trying not to drive myself nuts with Dr. Google right now.) Vet said it suggested he'd gotten into something toxic - although I can't for the life of me think of what that could be - or possibly an issue like Cushing's. I was ready to do ALL THE TESTS but they said we need to get him eating enough calories and hydrated first, then re-check and go from there. So they sent us home with Cerenia (for the eating trouble), Denamarin (to support liver function), and some i/d canned food. So far so good with that - with the Cerenia he's keeping down water and small servings of the stinky i/d food.
He's still jazzed about the things he usually gets excited about (going outside, car rides, things that smell terrible, attention), but he's definitely more sluggish than usual - although not eating would also contribute to that.
Basically the good news is, the clean x-ray and the fact that his bowels are moving normally rules out a lot of the immediately scary explanations, which is good, but it's hard not knowing what's going on. I'm trying to be honest with myself about his age and everything, but I just want my boy to feel good and be happy. (And also to live forever.) It's especially hard because he's really a once-in-a-lifetime kind of dog. Also, my Queenie passed away about a year and a half ago, and I don't know that I'm ready for all this again already.
