My rescue Welsh collie loves it.great entertainment.

This is a great value, well made product. But we found that it was to hard for our 7 month old border collie. That's only because he is very lively. We wil save it for when he is a bit older.

Oscar, a collie, had a larger Boomer ball inherited from our previous dog. He managed to split it. Looking on PetPlanet I learned that a smaller ball would be better for him. Wow! From morning till night he chases both the red and blue balls from one end to the other in our garden. He uses his nose, his paws and body to chase each ball with obvious enjoyment. He exhausts himself! He tries to engage any visitor in a game of football rolling the ball at their feet and waiting for a response. Fantastic activity for a very active dog. Original ball survived strenuous play over 15 years and I am hoping for the same from the new, smaller balls.
