Finally, a ball that made it!
Color: Blue, Color: Blue
I don’t know what is it with this ball, but it’s special. My dogs can absolutely tear up anything and this one seems like it can be chewed up but my dog loves it too much. He carries it all day, nibbles it and loves the squeaky sound of course. Finally found a winner!

Good size ball for my big boy
Color: Purple
My big boy loves this ball. He chews and chews and chews on it and it ain't made a dent in it. It's made a good quality rubber. It's got a squeaker in it. He hasn't managed to get it out which is not normal because normally he can get a squeaky out within 10 minutes. He goes through toys like I don't know what so it's being being a good. Really good ball. We've had it for about 2-3 months now and he hasn't been able to break into it and get squeaky out or even make a dent into it. That would tear up the the rubber

Sturdy ball, holding up well.
Color: Purple
I have a ball obsessed Shih Tzu. This has become his security blanket. He literally takes it everywhere and even sleeps with it next to him. Dexter loves any ball. All shapes and sizes. He will play fetch all day long if you let him. He doesn't know when to quit. It can be 100 degrees out with 80% humidity and he'll fetch all day long. This is a larger ball, I think just over 3 inches. It is entirely too big for a Shih Tzu, but it is perfect for Dexter. He came to us with a ball similar to this that he has since lost. He carries it in his mouth by placing his incisors in the indentations and lets it hang out the side of his mouth. Quite comical actually, but it works for him. We have bought him balls more for his size, but they're too small and he gets them lost under cabinets, furniture or any nook and cranny the ball will fit. And being obsessive, he will bark and carry on because he can't get to the ball until you come and rescue it. Difficult on our old knees. So he ends up getting the smaller balls taken away from him. The other night he was laying and chewing on this ball. It sounded like he was shredding this ball to pieces. I was afraid he would choke or swallow the rubber pieces, so I took it away from him. There wasn't anything wrong with the ball. It looked brand new. No chew or bite marks that I could see. I was impressed. It does have a squeaker, but I can barely get it to squeak and I have strong hands. A larger dog with a stronger bite force could probably easily make it squeak. It claims to have a beef scent to the toy, and maybe that is why he likes the ball so much. But I sniffed it and couldn't smell anything, which is fine by me, it won't have an obnoxious smell to where I don't want it around me.

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).
