My blue heeler mix suddenly started eating poop at around six months. We went to the vet and there wasn't anything medically wrong with him and she said we were feeding him a good food in the proper amounts. We've tried deterrents and keep a close watch on him, but it's been a month and he still manages to find and eat other dogs' poop before we can stop him. We really don't want to stop taking him to the dog park because he loves running with the other dogs, but we can't think of anything else to make him stop. Has anyone else had this problem and figured out what to do?
