We have an indestructible ball and a jolly soccer ball. She loves them both but I prefer the soccer ball because the other ball is HARD. Like if she runs into you with it it hurts, and I worry she'll damage our fence with it or hurt herself. The soccer ball is much more robust than a regular soccer ball, she hasn't been able to get her teeth into it yet. I think she likes them both pretty well. The ideal would be a much larger sized soccer ball that was soft, so maybe this collieball fits the bill!
