My 11 yr old cavalier is on Vetmedin, furosemide and Fortekor. I believe that the Vetmedin is the cause of chronic Diarrhea. I know that she must take the Vetmedin but what can I give to help the diarrhoea. She has only been eating chicken and rice and sometimes not even wanting that. Could that make the problem worse? She is having to wear a nappy in the house which is not pleasant. Has anyone any advice please.
