I'm used to high energy dogs (I have Border Collies) and give them plenty of exercise.
I also now have a Belgiam Tervuren pup who has no prey drive, so doesn't go after balls, frisbees, etc.
I know he needs to work off some of his excess energy physically (not just mentally, which we do.) It's not practical to walk him for that purpose, nor is hiking every day up rough terrain practical.
I tried to train him to chase a ball (there is a kong toy that holds treats and "folds" into a ball-ish shape), but that was a no go. I tried treats and praise when he even looks at the ball I throw. No go.
He loves to herd my Border Collies, which I let him do, but it's not totally fair to my BCs, so when I chuck for them, I have to leash the little one so he's not overly annoying the older dogs.
The three of them get walks twice daily. I was thinking of agility-type things, but he's still too young (he's only about 4 months old).
We do play a lot in the house, but it doesn't tire him out like running does. And my adult dogs have taken to him beautifully, playing and roughhousing very politely (so proud!)
Any ideas would be appreciated.
