Thanks..our petstore believe it or not doesn't carry them yet (they just opened!) I ordered one online, my trainer said to buy him the same size I would a reg. collar. I get the general idea of how it's supposed to fit, and I tried it on him and it seems to work well. I'm not 100% sure I'm doing it right so I will bring it to class with me and have the trainer show me how to properly fit/use it.

Thanks again for your help.
