So Clo had begun the same hacking as Erns had. We knew there was a heart murmur & figured it was just a matter of time. But, he keeps on a tickin'. Since he seemed determined, we figured to get the swamp rats out of his mouth with a final dental cleaning.
Sure enough, in the x-rays he has an enlarged heart, possibly a mass there as well, plus a bit of gunk in the lungs. There are lots of expensive options to nail this down, but how does knowing exact details help him or us?
So, our vet (who is totally awesome), started him on some heart medicines. Are there side-effects? Yeah, but it's worth a few extra trips to the yard. He still sleeps a lot and hacks a little here and there, but overall he is much more bouncy and enthusiastic. He even plays again - yay!
Guess we're well past middle-age, but so happy that he can feel comfortable and good. Hope it lasts a while. Here's little bud giving me a morning bath and napping with Mr after a play session...
