Ted is currently working towards his advanced certificate in obedience and I have been having a hell of a lot of trouble with his retrieve. (I think I have the only GSD on the planet that doesn't like to play fetch).
He will bring the toy back but then runs out of interest and drops it half way back to me.
I have tried all sorts of things with no success, until this weekend when I made some liver cake.
Suddenly he will do anything for me, including understaning the "hold" command which he has previously thought of as a foreign language when I used it.
There has been about 100% improvement in his attention since I started using it as a reward so I am planning to use it from now on. I am only using it for training treats so he doesn't become too bored with it.
It just goes to show he knew what I wanted all along, he just needed the right incentive.
