I am so sorry your baby is suffering
! How scary for you. Enalapril is for high blood pressure and heart failure (or, heart "congestion"). Furosemide is a diuretic - which keeps the blood more "thin" and is also given for heart failure. I don't want that word "failure" to freak you out - the whole term is "Congestive Heart Failure" - which, in laymen's terms means -> the heart can't properly control blood volume and can't pump properly either, the heart is often enlarged and a bit "flabby" too. These meds help the heart function with this disease.
As for the "episodes" of going limp, please call the vet bc this could mean that the dose of enalapril is too high - and may be causing his blood pressure to dip too low. It's hard to say, but it's worth checking. Have the dosage double checked too. It almost sounds like he's fainting and losing his bladder. Please keep up posted.
