Yeah, works on most! I have used a similar method when required but with two bicycle wheels mounted to stakes. Seperate each wheel around 10metres apart with a rope looped around the wheels & joined. Tie a clip to the bottom rope run & you can do both - cast the the dog away (i say "GO") by grabbing the rope or wheel and send/spin it away.....Do the opposite for "HERE".....

I'll see if i have a picture of the set up
genius!
