Barney looks happy and comfy - can just go to his food dish and EAT, which is something he didn't do for a very very long time.

In that one part of the video - can he HEAR the dogs? Maybe he senses a vibration?

Great to see dear Barney...please give him gentle hugs for me.

You're still giving him the immune stuff that Angela had? I do hope for a miracle...but as I said before, right now is a miracle for him to be inside, loved, warm and fed - not necessarily in that order!
