Thank you very much for the well wishes.

I just took a picture of his paw:

The lump is actually quite a bit bigger than just the pink spot. The area I circled in red is all swollen.

Yes, it was so much FUN to have him at work today. By the afternoon he was totally comfortable. My coworker took him for a walk when she went down to get coffee at the gas station, which he loved. The only thing is, he wouldn't drink water for me the whole day. I think it's because the bowl was different than the one we have at home. Silly dawg!!
