Warning. I just found out a friend of mine had thier Doberman PTS. He snuck a corn cob out of the garbage. They seen and took it away. ABout a week later he started throwing up. He had ate another one before they seen the one they took away. They took him in for surgery, and they removed the cob from his intestines, but it had allready rotted away part of his intestines. He didnt make it. Please be carefull!
