“I bought Enalapril for my old dog whom is suffering from congestive heart failure. She passes out when she gets excited and is often panting for no good reason. This medication has made a noticeable difference for the better. She is also on Carprofen for arthritis in her hips. Too high of a dose - the two meds combined - causes her to lose her appetite, become lethargic, and have diarrhea so be alert.”
