I would ask the vet what the ongoing medication plan would be, and go to the pharmacy or check online to find out the costs, just so you know what you're getting into.
I adopted AJ two years ago knowing he had chronic heart disease (he died a week and a half ago.) Every year he had to go to the cardiologist for an echocardiogram. It was over $500 just to walk in the door. In the end he was on about six heart and blood pressure medications. I was afraid to add up the cost. Between the heart disease and his other ailments, it cost me thousands of dollars in the two years I had him, but I could afford it so I did it.
Bailey had chronic kidney disease for 7 years. He ate special food and took meds. Again, the specialist vet cost a bundle.
Personally, I couldn't ignore my pet's health problems. But dealing with chronic illness is draining, emotionally and financially.
