One of my previous cockers had an enlarged heart, tracheal problems and fluid build up and she was on similar medications. She started coughing when she was 7 years old and enlarged heart was diagnosed. Vet put her on theophylline at that time and was on it for 5 years before changing her to Enalapril and Lasix, which is a diuretic like Furoquid. The meds did help and she lived to 14 1/2 with a very good quality of life during the entire time. For the last 3 or 4 years, I home cooked chicken and brown rice with vegetables and gave her a senior multi vitamin to help with missing nutrients. This was several years ago when chicken and brown rice was recommended for heart conditions–don’t know if it is still the recommendation now.
I am sure some of the other people here have more knowledge about this than I do and they will be along to give assistance.
