My lab pup is almost 9 weeks old, have been training her to retrieve in a hallway, throwing a small paint roller or larger one. Was working GREAT, for a week. Last week tried, she had zero interest in retrieving, but worked with her and got her to retrieve a couple of times, called it quits. Now is to point that all she will do is continually sniff around for something to eat, completely ignores paint roller.
Any suggestions as to how I can reboot?
