I got one for my hound. Both my dogs love it. It takes some training like right left stop and go but they learn really fast. I think any high energy dog would enjoy it.What are your thoughts on this device for a high energy breed? How much time using it do you think would meet the exercise requirements of a high energy breed? Yes I know it depends but what range would you expect? Do you think it would work well with a brittany? That's one of the breeds I'm considering and I know they like to run.
