My first Cavalier Cricket had some minor heart changes, I think a slight enlargement (just natural age realted)
She was just about 10 yrs old? My cocker "Peaches" :) had just passed away from CHF (congestive heart failure) and cancer. I wanted my Cricket checked really good.
Cricket was put on vasotec 5mg and laxix. She never advanced more than that minor change and she passed away at age 14 and not due to her heart. Even at 14, the meds had kept her heart in great shape. She had age related arthritis. I guess if they are 14 we don't have to look for a reason why they pass on. She was terrific, and wonderfully healthy all her life. She tolerated her heart meds great.
I don't see Vasotec being used much anymore?
