Put a belt on his pants (if he has loops). He probably won't be able to remove it. You should express dissappointment when he doesn't use the potty chair. Do not punish him......just let him know that you are not pleased with what he did. The dogs eating his poop is no big deal....it won't hurt them. My dumb dogs eat each others poop....disgusting but the vet says some dogs just like it and not to worry. I just don't kiss them or let them lick me. When he plays outdoors just make sure that you make him come in every 15 mintues to sit on the potty and try to poop whether he likes it or not.
