Yep. And you can work on training too!!!
This is one of my dog's favorite games. I put them in a sit stay or a down stay and then I walk all the way across the field. When I get to the other end I yell "OK" and they come flying. Repeat repeat repeat!! LOL I also do this going up and down hills, good for conditioning! You can also not go too far away and then run a bit away from her as you say ok, it doesn't have to be fast it just has to look like you're running away and she'll really put on the speed, at least my dogs do.

Here are some dogs I babysit playing that game with me.

Down stay


OK!


And some of my dogs (and pug friend) playing.

Sit stay
