My husky loves it. It's one toy she's not been able to destroy yet. She plays without when she's outside in her lot and will play for an hr at a time. She loves it moves and bounces instead of just tossing it and letting her fetch. The battery life is really good. We charge it about twice a week. It's quiet, so she loves that. It's perfect size for her.

They love it! Good quality toy.

Color: Orange

My dogs love this ball. The texture is perfect. They like being able to bite it. It doesn’t tear apart when they do either. Other interactive balls I’ve purchased have been hard plastic and much louder. Everyone is enjoying this toy more than those. It’s so fun to watch the dogs play with this. Video is from the first moment it arrived. They both play with it hard now. We’ve had it three days. I’ll update its longevity if it’s shorter than I feel it should be.

Keeps dogs busy.

Color: Orange

The dogs love this ball. They are afraid when it vibrates but as soon as it jumps and moves around, they are on it. They will play with it for quite awhile. Charge lasts for a long time. Very durable. This dog can tear anything apart but it's still in one piece.
