Oh my gosh, I learn something new every day!! I had no idea that they used this kind of equipment and exercises for dogs! Are they used to increase strength and fitness for agility etc.?
Yep! The ones Cheryl posted are used to create rear end awareness, which is basically the dog realizing that they have back legs that can move somewhat independently. Using the balls allow them to work that, plus strengthen their muscles.
There are also other balls (like people exercise balls) that can be used to strengthen a dog's muscles everywhere.
Here's a good video: http://www.youtube.com/user/wizardofpaws1?blend=22&ob=5#p/a/u/0/TgBcd11zGO0
