Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

I bought this interactive ball for my dog, and it has been an excellent purchase.
Color: Blue, Color: Blue
I bought this interactive ball for my dog, and it has been an excellent purchase. He loves playing with it because it moves and bounces on its own, keeping him entertained for a long time. It feels durable, is easy to charge, and is of very high quality. I would definitely recommend it to anyone looking for a fun, long-lasting toy for their pets.

Great Interactive Dog Toy!
Color: Red
My dog absolutely loves this interactive ball! The material feels durable and stands up well to chewing. The bouncing and moving action keeps my dog entertained and active for long periods of time. It’s also easy to recharge and the size is perfect for medium to large dogs. So far, it has worked great and seems built to last. I highly recommend it to anyone looking for a fun and engaging toy for their pet! 🐶🐾

Not Golden Retriever Proof
Color: Red
My Golden Retriever destroyed this ball within a couple hours of receiving it. Turned my back for a minute and she had it open and chewed on the internal part wrecking the charging port. Then proceeded to rip chunks off of the outer part. This is a great idea but maybe make it more difficult to open. BTW, my dog loved the ball when it was functioning properly.

Great Interactive Toy
Color: Blue
This toy is amazing for keeping my dog entertained and active! The movement feature really grabs my dog’s attention, and he loves chasing and playing with it. It is strong and durable, and the design is very cute.
It’s also great for preventing boredom, especially when my dog has extra energy. The battery lasts a good amount of time and it was very easy to set up. My dog plays with it every day and hasn’t gotten tired of it.
I highly recommend this toy to anyone who wants a fun and interactive way to keep their dog happy and busy!
