Many people will remember when I almost lost Marcel about 3-4 yrs ago when he started choking on the end of his CET chew (the petite size). He was dying right before my eyes.
Even if you don't give chews, EVERYONE should learn how to do the doggy Heimlich and how to rescue breathe. Your local Red Cross often gives PET CPR/FIRST AID courses; we took it and it was good.
Here is a thread about the Heimlich:

Print these, put them on a bulletin board or something. Or in your dog kit.
