Thanks Guys.
I posted this thread from my laptop and didn't have a pic of Colby on it. Here is one from my files. No longer a "bag of bones" as you can see.
It was amazing to watch him go out after a storm, stepping high and plowing through the drifts.
If he got "lost" sometimes he'd run into things, but he'd just shake it off and give it another go. Amazing role model.
Best
