I have my 3 cav to the vet today for their pet check and boosters. Barney (4 yr old tri) and Ruby (6 yr old Ruby) both have know murmurs and Ralphie seems clear so far (6 yr old B&T) So the vet has put Ruby on hearttablets and says her murmurs got worse and she had some fluid on her lungs. As far as her behaviour goes shes just the same but I'm thrown!! Shes my wee Baby! I can hardly look at her without wondering if I'm gonna loose her!! I'm going back to the vet tomorrow to pick up more tablets and am gonna ask him more questions but the tablets shes been given are the ones for congestive heart failure! Im oping this is just to get rid of the fluid and not a statement as to how bad her heart is!!!
