Hello. I would need to know a little more information about Walter's heart first, such as with an x-ray & ECG, but if he is not coughing, there are no crackles or wheezing in his chest, he seems to have good energy, & appetite is normal, then no, I would not necessarily put him on any medication. But I would recommend rechecking chest radiographs in 6-12 months. I would also recommend doing a NT-proBNT test. If the results are high, then Walter may be at risk for actually developing congestive heart failure, & treatment with pimobenden is indicated. A low to normal NT-proBNP, I would not start any medications yet. Thanks for using Petco Pet Education Center, formerly Petcoach.
