This interactive dog ball is a total game changer! The automatic rolling and bouncing keeps my dog entertained for long stretches, and the lights make it even more exciting, in the evening. I love that it’s rechargeable and waterproof, so we can use it both indoors and outside without worry. It feels durable and well-made, perfect for medium to large dogs. Also works great with toddlers.

Fun, interactive toy!

So much fun! Bought this for my lab. She wasn't sure what to think of it at first but seems to love it now! I like that it's rechargeable too.

Happy puppy.

Color: Blue

My puppy loves his. He carry's it around and throws it. He knows how to turn it on himself. Charges quick.

Overall, I highly recommend it!”

Great toy! My dog loves it 🐶 The ball moves on its own and keeps him entertained for a long time. It’s perfect when I’m busy or not at home. Good quality and fun, but maybe not the best for very aggressive chewers.
