Why do dogs eat poop? I have a male Border Collie that is just superb, I've trained him to do almost anything and everything, from obedience trials, agility and flyball! He excels at everything he does, except that I have this HUGE problem that I CANNOT for the life of me! My dog Taz eats poop, his own poop and the poop of my other dogs, it is utterly disgusting! I have tried punishing him by catching him in the act several times by pinpointing the bad behavior with a loud "ARGH!" and giving a shake, I've even resulted to trying a remote shock collar and used it about 10 times while he was eating poop. It didn't work! I really have no idea what to do, thus me asking this question on this forum. I am ashamed of it because my dog is just such a wonderful dog and everybody loves him, but I have to tell my friends not to let him kiss them because he eats poop. I just cannot tell you how disgusting it is to have a dog come in at night and you can smell poop on his breath. Makes me want to vomit! I need help! Please help!
