I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch

Size: Medium

My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Picky dog approved!

Color: S6-muti-color, Color: S6-muti-color

I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
