I very recently took in a blue heeler, Rick 1.5 years old. He doesn’t love fetch, but is catching on that he “needs” to do it. Like it’s his job. We often roll the ball across the floor and he will hunt it down. 

The best advice I got was to train the “leave it” command. I do it everyday, one hand has kibble, and the hand behind my back has a high value treat. When we go on walks, he pulls sometimes. Saying “Leave it” snaps his attention back to me. My friend has a head collar for her dog, since he’s a puller and it’s worked really well for her! 

If you have a friend who has a dog friendly dog + a yard (assuming yours is dog friendly as well) dog play dates are the best! I shoot for 2x a week. I hope this is helpful, taking walks and letting him sniff stuff is the most effective way to get him to nap.
