Housebreaking a male Border Collie!!!!!! Update pg 6.

Be aware that once you have tossed an item (toy, rock, stick, shoe, glove, etc) for a Border Collie that knows fetch:
1. that dog will continue to bring the item to you to be tossed until your arm falls off
2. fetch increases a Border Collie's physical stamina without tiring the dog for long
3. that item is only good for tossing and is no longer good for self amusement
