What a great toy!
Yeah - our 17 month old German Shepherd LOVES this thing (I'm ordering another one right now for even more romping play! He's had his purple 10" one for 8 months now, and is just berserk for it. I even got him a 6" one for play in the house. Best toy, and money spent, ever!

Worth the Money!
I read many reviews before purchasing this for our Black Lab. Our lab loves to be outside and before the Jolly Ball he loved playing soccer with our kids or just having a ball for us to kick that he would retrieve. However, when play time was over he liked to chew on the soccer ball and of course eventually it would pop. So in my quest for the ultimate soccer ball I found the Jolly Ball, large enough to kick like a soccer ball, durable enough for him to chew and still stay inflated. He loves it and we all love to play with him as well as watch him run around the yard entertaining himself as well as us :)

Jolly Pet 10" Horse Jolly Ball
Our 75 lb. dog loves the ball. She is a 'power chewer' and has managed to chew off part of the corner of the handle, but the ball doesn't deflate. It is otherwise extremely study and provides her with great entertainment and exercise. Also, the ball does not have the offensive, noxious chemical odor found in some pet toys.

Made For A Horse But My Dog Loves It Too!
I was planning on buying the 8" model for my 3 year old Shepherd/Lab mix. Then I saw the 10" version for only a dollar more and decided to go for it. (Couldn't pass up a bargain!)
I ordered it one day and it arrived the next! I don't know how that was possible but it happened. When I opened the carton and saw the size of this thing I thought I had made a big mistake in getting the 10" size. I couldn't imagine how the dog could get his mouth around this huge ball. Well, it's been a week now since it arrived and I am happy to report that T.J. (Toby Junior) loves playing with it and has figured out the bounces and way to grab it and would probably want to sleep with it if I let him bring it into the house. His favorite way to catch it is to grab the ball on a full "gallup" after only one bounce. If this was an event in the dog olympics I bet that T.J. would win the gold! The ball is extremely well made, will not deflate, as is advertised, and we are both getting a good workout throwing and retrieving it. I can't recommend this ball more highly if you have a large mouthed dog and a large backyard. I'm sure it's fine for horses too!!
