You are welcome! I wasn't sure if it would help, but I thought it couldn't hurt to give you my experience with the disease. With Peanut, it most definitely was progressive and for that I am very thankful. It gave us time with her and allowed us to prepare (though one cannot ever fully be prepared) for the time when her little heart was just too tired and would eventually give out on her. Though, when she was first diagnosed years prior to her passing, I was in disbelief that she was even sick! At any rate, we had many years with her after that time and we will always be grateful for that.
Peanut started the enalapril immediately following her diagnosis, she stayed on the enalapril up until she passed away. One year following her diagnosis was when the vet added the Lasix and Vetmedin in conjunction with the enalapril once her heart worsened. So she was on all three meds, but the Vetmedin is by far the best in my opinion. I would definitely ask your vet about this medicine during Bandit's next checkup.
I am SO happy to know that Bandit is still acting like himself and playing! I am sure he will continue to do so! Its so funny how they love their toys, isn't it? Peanut had a few favorites too - a few fuzzy balls and a Lamb Chop toy my mother gave her.
Please keep us updated on anything new with little Bandit! I know he will live a long life full of toys, love and happiness.
