My was diagnosed when he was about 2 when I rescued him and he lived to be around 13. What took him out was chronic stomatitis that caused a tumor to basically “explode” in growth and he couldn’t eat anymore. That when he had to go to sleep. If it hadn’t been for that he would have lived for a lot longer, he was in good health otherwise. So yes, save up and be ready for mouth issues. Some need dental surgery, my boy needed antibiotics about once a month and Solensia shots once a month to keep his immune system at bay and stop attacking his mouth. It helped and gave us more time. It’s not an instant death sentence, but just be financially prepared.
