First find a stem and give in a good wack with your left paw and repeat 3 times (I must apologise for the quality of this picture as Mum couldn't keep up with the speed of my paw). Sometimes you just wonder at their fitness!!
Change to your right paw and repeat as before (I had a stern word with Mum and she seems to have got her act together now and this picture is much better)
Thirdly find a lower stem and really stretch your back when you wack them - repeat 3 times with both paws.
