Thanks for the tips, Phred.
The glass was a broken jar. I believe it was larger pieces. I did check his paw thoroughly to make sure he didn't step on a piece too. The cut isn't very deep. But of course, if it doesn't seem to be improving I will be taking him to the vet.
I do have some Phooey here at the house. I could try that, but I've tried that on Zoee's tag cover and it didn't seem to phase him. But hey, I'll try what ever I need to.

And thank you D&D for the get well wishes.
