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😂

It broke within the week
Color: Turtle
The toy was ADORABLE, it worked very well for the first week. And then it broke. I bought two for my puppy and my 8 year old shih tzus. It stopped vibrating and just made loud grinding and squeaking noises. I would recommend this toy if it lasted longer.
