I posted on here awhile back about my dog, Barney, He'd gone through a bout of heartworms a few yrs back. Now he is having repercussions from it. He was put on VetMedin, Enalapril, Lassix and Diltiazem. My husband thought he seemed worse lately with coughing constantly, so he stopped the meds for a few days. Now Barney isn't coughing but seems a little unstable on his feet....he's 11 1/2 yrs old.
Does anyone have any experience dealing with this?
