I'm looking for training ideas for my 1 year old GSD.
Typical of the breed, he needs as much mental exercise as physical so I try to build some training time into each day (I mean inside the house, not things like loose-leaf walking, recall etc that we do out on walks).
I've trained the following skills (obviously I keep them ticking over): sit, lie down, paw, leave it, waiting at an open door until he's told he can go in, go to his bed, basic 'find it' with a hidden treat.
What else could I do to keep his little grey cells working???
