I 'm using different balance balls so Dazzle can do some tricks on them. The balls vary from small ones where she only has to putt one paw on to big ones where she can stand on completly. I also like to work with the balance ball so she can improve her balance, mussle strenght and body awereness. Next to that, it's a though training, so she only stands up ro one minute on a ball, and then she rests for atleast one minute. So, are there more doggie balance fans out there?
