Dogs love balls
Color: Orange
Most dogs love to play with balls. This is a ball.
It squeaks and can handle a lot of strong chewing. Quite durable and a good size for medium and up sized dogs. (Honestly even smaller dogs would have fun with this).

Heavy duty for sure
Color: Purple
Heavy duty toy. This ball has some weight to it! I have a smaller laber doodle that thinks she's a German Shepard so no toy is too big or heavy for her. She's been chewing on this for months but you'd never know it. The squeaker is even hard for me to activate with my hands. She hits it in the right spot every now and again and gets excited about it. Great if your not crazy about hearing a squeaker squeaking non stop!

All dog sizes can enjoy this ball!
Color: Orange
This is a terrific dog ball! Our Pittie can't tear it apart on day 2 which is unusual! Also, its big enough that he can't swallow it but not so huge that our mini Doodle can't enjoy it too! We have more than one of these to keep our pups busy!
