Thanks .....I thought the same thing when I bought this ball....but it is a exercise ball for humans by golds gym...I bought it at walmart for like 9 bucks and they have not popped it yet and believe me they have tried to bite it..they have almost stood on it and even their nails havent popped it so it is wonderful....they love it soooo much !!! Also my 17 year old son took that pic of Sarge when we went and got Lou Lou Belle in Ga.
Jolly ball makes a big hard plastic ball like that and it's pretty much indestructible. You can even put loose change or nuts inside of it so it makes noise when it rolls. Awesome pic too!!!
ohhh jameson used to have one just like that he LOVED it...it lasted about a year...then somehow it deflated just enough when i wasn't paying attention and he got his teeth in it....ooops...he used to put his paws up on it roll it around and bounce on it...at first i thought he was humping it but he wasn't pushing down on it with his front paws...
