It could mean that they are just slowing down over time, just like we do. We start to slow down as time goes on, our bodies start to wear down, and we don't have as much energy as we used to. That could be what's going on, but you also want to check in with your vet. It could mean that they have a health problem that needs to be addressed because, for some reason, they don't feel so well.

Some dogs, no matter how much exercise you allow for them to get while you are home, can still be destructive. That's when crate training comes into play. But, if they have a toy that is fairly indestructible that they enjoy chewing on, you can give that to them. If you are able to take them for a nice long walk before you leave, you can get some of that energy out so that they're tired and sleeping while you're gone.

You can make training a little bit of a game. Having them sit or lay down and rewarding that with either throwing a ball or giving a treat are all things that they learn to look forward to. Things like fetch and learning to stay or to come are also good methods to train them.

Indoor wise, if you want to play fetch, you can have at it. They will still enjoy it no matter where the ball is. As far as their rope toys go, some dogs enjoy things like tug of war, or even just allowing them to have a toy that they enjoy chewing on.

One of the favorites, at least for this guy, is fetch. They love having a ball thrown for them, which allows you to interact with your dog. They are responsive; they know you are the source of that ball being thrown so they'll bring it back to you. Chasing it is certainly a lot of exercise that they also get. Tossing a Frisbee or even just going for a walk or a hike can keep them active.
