Durable, Rugged, Dog Approved Fun!!
Style: Original, Style: Original
This thing is durable and worth every penny! I bought this over 5 years ago for my rescue and he STILL loves it. He plays with it near daily and it's got a LOT of love-work scrapes, scratches, and scuffs. But it still works perfectly!! Because he's on the medium side, he can't quite bite down on it. Not sure how it'd hold up to heavy chewers with larger mouths. But he can play with this solo for ages and has SO MUCH fun. We love to listen to his "conversations" as he gets into it with this ball. It's been a winner since the day we took it out of the box. It's also the longest lasting toy we still have! Everything else either wore out, was destroyed, or broke. This battery-free ball has made the cut for us.

Lasted a day for my dog
Style: Original, Style: Original
My dog absolutely loved this toy, but sadly it didn’t even last a full day 😩 I’m not sure if that’s because I have a Rottweiler/Lab mix with the jaw strength of a tiny excavator, or if the durability just isn’t great. Within a few hours, he had already torn right through it 🥲 That said, the sound it makes had us cracking up and definitely kept my dog entertained and intrigued while it lasted!

Great toy!!!
Style: Original
My dog went mental over this ball!!! She will let me roll it through the backyard or in the house and she will go nuts for it but the great part, she will play by herself with this ball. She will roll it and jump on it and just have a blast.
Since this is not a normal chew toy, my dog's big, she only gets it when I'm with her. It kind of makes it our special thing when I pull it out. We play every day with it and her enthusiasm has never lessened. She can be in another room when I take it out of the cabinet and the second she hears it, she will run into walls in her rush to get to me so we can play! It really is better than just throwing a ball back and forth. She's completely engaged the entire time it's out.
I highly recommend it but just know it's not a normal toy that you can just throw to your dog and walk away. It is an amazing toy to help you bond with your pet.

Great for dogs that need to stay busy
Style: Original
My dog absolutely loves this ball. It is a little noisy so we take it out in the yard and let her play with it there. I highly recommend it if you have a dog that get bored easily. This will surely keep them busy.
