Slippery basin gives an extra challenge in this treat hunt.
At the first time I put one yoghurt cup into the basin face down. Then I put a treat under it and asked Miki to search. After a couple of easy games like this I put three yoghurt cups into the basin and I put a treat only under one or two of those cups.
This game was relatively easy for Miki. Every treat I put under the cups vanished in a few seconds, although I moved and mixed the cups in the basin before I asked Miki to search.
You can make this game harder by replacing the yoghurt cups with a kettle lid or even with a dinnerplate. But you need to use some slippery underlay, like a basin. The idea of this game is that the dog needs to use his nose to figure out where the treat is hidden and also to move and lift the cups which are moving on a slippery underlay.
