Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too. I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

This is a great ball for high energy dogs.
Color: Blue
I have a Belgian Malinois, so you can imagine the Maligator jaws. Just opened this today and let her play with it indoors. She LOVES IT. It wore her out and it’s a toy she can really stay focused on without needing me to throw or roll for her. It moves on its own! I supervised her play. I was hoping it was too big to get under the couch, but no. It goes right under it. I had to block off the gap so I didn’t have to keep getting it out from under for her. The outter “shell” is very durable! When she had resting moments, she chewed it pretty good - I could hear the material squeaking against her teeth. I was worried she was tearing it up, but nope! Not a mark on it. It’s easy to set up and operate. It needed charging before play. After hours of play, she was able to somehow unscrew the outter shell. This concerned me bc the smaller, inner ball mechanism came out but I saw it right away and was able to put it back together. So, make sure it’s screwed together tightly (which I thought I had done without breaking it) and check it from time to time to make sure it hasn’t loosened. This is a great ball for her incredible high energy drive. It gives her the work and fun play she needs to get tired, which I love. This toy is on the expensive end, but so far it’s worth it. Now we’ll see how long it lasts!

Love love it
Color: Blue
Best dog toy ever. I have a 1 year old boxer who is full of energy (understatement). This ball has provided more entertainment for us both than any dog toy I’ve ever purchased. Charge holds well and has a very resilient shell. I love it. Worth the price.

Great ball for limited entertainment. Replaceable outer shell is an amazing option!
Color: Blue, Color: Blue
Bought this for our 45lb, ball-obsessed Dutch shepherd/pit bull dog mix. I had one of these years ago with the hard shell and couldn’t be happier with the new foam shell. The new foam shell is much quieter and while our dog might put holes in it with his teeth, he doesn’t seem to ever pull pieces off. For engagement level, he found it VERY interesting at first and was scared to grab it, but once he got over that he started holding it in his mouth even when it shakes and just tries to keep it. Isn’t the best for fetch or anything as he has trouble letting it go when it is actively moving, but it makes him happy while he has it. We just make sure to monitor him while it is out. The ability to change the outer shell and just buy a replacement for the shell instead of a whole new toy is a lovely feature that makes me very happy to continue buying from this company.
