I looked at this:

http://helengreenley.co.uk/But I'm a loner and quite happy to do blind retrieves and underwater retrieves with my dog, for half an hour or so most days.
On our 10pm bedtime walk, I leave the dog in the house and hide a ball up the street, in the bushes.
Ten minutes later we come out ON LEAD and run full pelt until we find it. Make no mistake this is exciting.
By this stage I really don't know for sure where it is.
Rarely do we make a U-turn and go back to find it. Suddenly it's just in the mouth.
I will have made right-angle turns, gone round corners, behind bushes etc.
I am in awe how the dog can do this.
It's eerie. Like he can read your mind or see though walls.
I can see that in the forest I turn up leaves, disturb fungus and mark a nice route, but on a wet pavement, streets with the odd car passing. How much track can a rubber street shoe leave behind?
I know from experiments that he must be within 10 feet to actually scent the ball. But he does finally home in by doing this.
A great sight is to hide the ball 5-6 feet up in a tree. He will do his best to climb that tree.
When I come and knock the ball out for him to catch it, you can see the sense of satisfaction and achievement he gets.
I'd encourage everyone to try these games. It has helped with guarding problems, recall, leave, stay and all the usual training stuff. To hide and find you need to also do these other things.
