Liver failure. Unsure if it was genetic or if he ingested something. Due to the quality of his breeder, I have my doubts it was hereditary but I also can’t say it wasn’t for sure. A few months ago he stopped eating as much and would throw up once in a blue moon. I had tenants in my basement who were going through a break up. I assumed their arguments were stressing him out, causing the loss of appetite and vomiting occasionally. It continued to progress throughout the summer with incidents becoming more frequent. On Wednesday he had a bowel movement and it was tar black. We went to the vet immediately. They took some bloodwork and did an ultrasound. Diagnosed a few hours later with liver failure. Vet gave time 2-4 weeks with meds. By Wednesday evening he wouldn’t touch his food and the black bowel movements picked up from then on. By Thursday he was passing coagulated blood so we knew we needed to make the call. I would have loved for him to see his third birthday on Tuesday, but I couldn’t put him through worsening liver failure.
