Judith Manhattan, NY 6/7/2010 6:01:32 PM My dog has an enlarged liver and heart and has a healthy appetite for meat. She does not want to eat anything else. I have her on lasix 1/2 per day. I try to skip about 2 days a week but when she starts coughing and gagging I continue the dose. A vet recommended giving her Liv20 which I hope to try this week. She is ok except for heavy and fast breathing at times. She is alert and does not seem disoriented. She is a 13 1/2 year old mixed small breed. What do you recommend for the enlarged liver and heart?
