I've heard from his mommy twice so far

She said he is adjusting very well, and even starting to play & run around a little. His muscles were very weak because he never got any exercise, but is doing better now.
She said he's even been eating some milkbones (nope, he never got anything like that before )
Him & the cocker aren't on the best of terms yet, they are trying to decide who is going to be alpha.

Just thought you'd all like to know
