What a fun toy!!!
Color: Turtle
This is the first toy in a very long time my 10yo GSD wants to play with. She actually brings it over for me to turn on. It is loud and wiggly... She goes nuts for it! So far good quality with shaking and light chewing. Very easy to turn on and off. Great value for the play enjoyment of my sweet girl, gets her up and moving.

Toy to keep pups busy
Color: Turtle
My puppy absolutely loves this toy. He runs after it all day and the sound isn’t that loud. The material is durable and he can not get to the rechargeable ball inside so it’s very safe . The material is thick enough for busy chewers and it’s so adorable . Great value for your money

Dog Loves this toy!
Color: Crab
Keeps our poodle entertained and excited. The rechargeable battery lasts a long time. You can make it play crazy music or just shake. It’s hilarious to watch him play with it. It’s very chew resistant, and believe me, he tries his best to destroy it. If you have a high energy dog, they’re gonna love it.

Great toy for puppies!
Color: Turtle
I love this turtle. My toy poodle puppy has boundless energy. She loves this thing. It keeps her busy so I can get laundry and other things done. I am buying a second one for when the first one loses its charge😂
