Reader Input: Dog Owners

Duke has crazy amounts of energy. This dog can run and play all day long and still want more, it seems as if he never gets tired.

I exercise him daily. We go out to a little open area behind our house and play fetch and he runs and runs in circles until he needs to take a 30 second breather and then he's at it again. I feel bad though, because it seems as if no matter how long we stay out there to play, he comes back and he's bored and still full of energy.

Thankfully he's not at all destructive when he's so bored. He's only ever chewed up one thing and that was a pair of shoes when he was 4 months old. So he doesn't chew things up; he doesn't get into anything he's not supposed to...we're really lucky in that sense, but I feel bad.

How do people with super hyper/active dogs keep them entertained all the time? We'll put him in the backyard to play and run around, but he eventually gets bored cuz there's no one else out there. I do exercise him every day, but he hates it when we have to come back inside. I play with him inside the house too, but I can only play so much before I have to get work done.

Any suggestions? He just looks so bored all the time :/
