dd (dog, that is) did some pointing practice last night...he got average, not top, marks. I put 2 balls on the floor and then told him to fetch, whilst pointing at one of the balls. on the whole he got it but was sometimes confused when I switched which one I was pointing at. or when he just wanted to go for his favourite. they were different though - I think that had they been identical he would have got it totally.
right, next mission is to get him to distinguish a cuddly duck from a cuddly cat.
