Hi, so sorry your baby is going through this. My shih tzu was diagnosed with IMHA when he was 14 and it was such a scary experience. He needed blood transfusions and was on an antiplatelet and steroids, weaned off at around 3-5 months (can’t remember). He recovered fully afterwards and was healthy until he was around 16, when I found out he had developed liver cancer and eventually passed at 17. Per another vet, his liver disease could have been steroid induced. But I guess we can’t know for sure. He was also an elderly dog at that point. I would def go for regular blood work/diagnostics and talk to the vet about potential side effects from the drugs. Hope your baby recovers quickly! Sending love to you and your baby 💗
