**Just a few more details on Grady:  Grady is STABLE.  He has been on the same low dose of medication since he began his long trek into the world of canine cardiology. He has recently lost a little weight, and as a result of that, his energy level has picked up.  Grady will never be a young healthy dog again, but he does love to play and interact with his playful siblings.  Grady is a sweet, sweet boy.
