Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry Chico is suffering from heart failure. Can you provide the milligrams (mg) of each medication? I don't think the medications are causing him to pant. If he hasn't had a recheck with your Vet in a while I would schedule one to be sure he isn't still in congestive heart failure or his heart has worsened He may need adjustments in his medications. There are other reasons too for an older dog to pant more: sensitivity to heat, Cushings disease, pain, fever and cancer in the lungs. I think you should have him rechecked by you Vet it is unlikely that he is on too much medications. I hope this helps and good luck!
