Harvey has started a HORRIBLE thing. He will not come to me when he is called. This is new when he started eating (horse or cow) poop on our walks ... off leash. Man, he is smart! If he has a big "pie" in his mouth, he won't get near me because he knows I'll take it out of his mouth. Well, that has turned into him not coming when called almost all the time.
Does anyone have any help / suggestions for me. Thanks!
