An Update
Well, Kurt doesn't seem to be doing much better. He's still acting like a zombie. My vet wanted to wait to wean him down to a low dose of Prednisone before sending him up to A&M. She thinks that the Prednisone could be making him act strange.
On Sunday I gave Kurt a bath. He usually doesn't mind this. But on Sunday he thought I was trying to kill him. I have never seen a dog so terrified in my life! He cried, barked, woofed, growled and jumped around like a jumping bean during the bath. Plus he used to be perfectly obedience trained, now he only listens to the "come" and "No" commands.
On Monday he was in the kitchen with Karen as she was preparing dinner. She had the door open looking for something inside and Kurt just tried to jump right inside the refrigerator! He knocked all kinds of things out of it. Fortunately, he didn't break any of the glass shelves and only went in as far as his front legs.
Unfortunately, we have this distinct feeling that the outcome of this is not going to be good. It's already starting to depress the both of us as the dog we used to know is long gone.
