I took the pups with me to Mums' today.. thought I would see how they went with a change of 'H' (habitat). They did great! Very focussed, no problems with working for food and toys, interchanging both out easily. This was the 2nd time I had shaped them to stand on a wobble cushion (first yesterday). The boys were hungrier than the girls as they missed out on a feed from Rosi, and you can tell as they were a little less happy to switch back to a toy.. but the reluctance was only brief. They are such fun to play with! They have already worked out that training is a lot of fun, you might hear the hysterics of the pups in the background on the vid, that wanted another turn!
