Doggie CPR and Hemilich maneuver

Are there any classes that would teach me doggie CPR and/or the Heimlich maneuver for dogs? Ringo is just so sneaky at times I worry that he might get a hold of something and start choking when I have my back turned.:( Please advise me on who to contact for this issue.
Thank you

I took a class sponsored by my local Humane Society & SPCA. I have the contact information for the trainers at home; I'll post it here tomorrow.

Update: Here's the contact information I promised.

The company is in San Diego, but perhaps if you write to them they could refer you to someplace in your area.
