Emma saw a specialist for her CM last week who listened to her heart and said she heard a slight murmur. She didnt even give it a rating it was so slight. So i brought her to my vet the following day and two of the doctors there checked her heart and both said that they didnt hear one and that its possible that because she is a cavalier, the doctor was expecting to hear one. That being said, I do want to be preventitive with her health because i know cavaliers are so prone to MVD. I bought Emma fish oil today and the doctor said to give her between 300mg and 500mg. I also bought her a new food, the new taste of the wild flavor that is made with beed and lamb. I know higher animal protein is good for heart health. Does anyone else have any other suggestions? Supplements, heart healthy treats or food, etc?
