Our dog is a 6 month collie cross and we play games with her like hiding treats under cups, she also loves (is obsessed) with balls. Our trainer has suggested these wooden puzzle games and a sliding door game by nina ottoson. They look fab but very expensive for something I'm not sure will get used.
So I wondered what other 'homemade' type games and puzzles you do with your dogs? I'm thinking things we already have in the house which we can make into a game rather than spending lots of money.
