My dog ​​loves it, but unfortunately it has figured very quickly :)

Have this bought as a job for my Sarplaninac Hybrid (47kg). Since he has made him immediately great fun loves intelligence games, and to my surprise he has got it almost right away. But it makes him still great fun!

+ Instructions on how to bring closer the dog's actions (for dogs, this check is not the same) - really good!
+ The four boxes are different can be arranged, so you can always take care of some variety
+ Very robust construction, so he hits really let it fly with the paw on it or bites in, no problem
+ Very fast and uncomplicated delivery

The only downside is perhaps that it is plastic, have normal all in wood, which I as a natural raw material is nevertheless rather. But for the game is relatively cheap!
