After a visit to the vet, we found out that Fergie has heart disease. We also found out that by 10, more than 50% of cavaliers have this. She will be 11 in February, so here we are. We started medication, and she seems to be responding to it. She gets off her chair sometimes, she wants to come outside, and the most telling, she runs in the kitchen for a piece of ice when you open the freezer. We are so happy to see her feeling like herself. Kingston agrees.
