This looked like a great idea for my energetic pup until I charged it and turned it on. It worked for maybe 3 minutes and she loved it while it was moving. It stopped suddenly and when I opened the Velcro to pull out the ball to check it, it was VERY warm. Unsafe for human or dog. For over $20 I would expect more for a dog toy. Cheap and non working! I will request a refund !

Great For Dogs With High Prey Instincts

My high prey instinct, Husky/Malamute, loves it. The moment it started moving she was on it. Wouldn't let her brother near it. Not noisy. Has USB port so you can recharge it. It's Very cute. Easy to clean you just pop off the covering and toss it in the washer. Great Brain stimulation - that also allows them to get their energy out - without having to talk a long walk in the middle of winter. Just what I was looking for.

Great little toy, the dogs really love it. Works great for kids also, they like to watch it wiggle around.
