Even better news.... I just got home and took him out of his carrier, left the door to the deck open, and he went out on the deck and is walking around! He was barely hobbling yesterday. He's looking and acting better already. I couldn't be any happier. Today driving back from Tacoma to get Charlie for the vet, I was depressed and dreading what I thought was going to happen. If it's diabetes, I'll be able to control it.
I am so relieved that things went so well at the vet.
