Hello! I'm hoping you all could provide some guidance. I've spoken with my vet but wanted an impartial opinion.
I have a 12.5 year old maltese. About 4 years ago she had a vaccine reaction and since then her liver values have been very high. I moved three years ago and the vet here connected her high liver values to her symptoms: lethargy, weight loss, vomiting, diarrhea. She was treated with medication for a few months until her values came closer to normal and she was asymptomatic but has been on a liver diet ever since.
Three years ago with the diagnosis of liver issues she had a bile acid test, ultrasound, biopsy, and probably some other tests I can't remember but nothing was able to determine the cause. We're thinking it's the vaccine reaction since it started about that time.
She's been asymptomatic since she recovered. Her values were never "normal" again but were much closer to the range they were supposed to be. She had her check up again last week and the routine blood work shows that her values are incredibly high again, about double what they were at her highest. The month or so she has slowed down some and gotten pickier with food but no vomiting or diarrhea. I probably should have taken her into the vet earlier but was in a little bit of denial on what it all meant. She will eat if I feed her food she wants, like grilled chicken. She's back on the medication as well.
My question is more what I should look at for end of life stages and how do I know it's time? My vet gave me the clinical symptoms to look for and "does she seem happy?" But I'm concerned she's in pain and I just can't tell. I'd like to have her as long as possible but on the other side don't want to prolong her life if she's in pain just because I'm not ready to let go. Since I've been watching a little more closely I have noticed that she's gotten a little less friendly with the other dog and cat that we have. Not aggressive but if they jump in her face she snaps at them, where as before she wouldn't. She's not playing with the cat any more either, and she was always the one initiating a few months ago.
Thanks for any help or advice.
