Extremely durable, highly recommended!!
Color: Orange
This ball was a game changer for us!! I rehomed an extremely needy 110 pound one and a half year-old male Rott. This ball has been keeping him engaged for hours giving a much-needed break to me.😜 it actually stays charged a lot longer than I thought it would, and so far he is not chewed through it at all, which is incredible to me!! I think I’m gonna order another one so that I can have one charging while he plays with one and then switch off with them.

A hit for Border Collies
Color: Blue
Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.

Best toy every
Color: Orange, Color: Orange
My husky loves it. It's one toy she's not been able to destroy yet. She plays without when she's outside in her lot and will play for an hr at a time. She loves it moves and bounces instead of just tossing it and letting her fetch. The battery life is really good. We charge it about twice a week. It's quiet, so she loves that. It's perfect size for her.

They love it! Good quality toy.
Color: Orange
My dogs love this ball. The texture is perfect. They like being able to bite it. It doesn’t tear apart when they do either. Other interactive balls I’ve purchased have been hard plastic and much louder. Everyone is enjoying this toy more than those. It’s so fun to watch the dogs play with this. Video is from the first moment it arrived. They both play with it hard now. We’ve had it three days. I’ll update its longevity if it’s shorter than I feel it should be.
