All the grinz balls are excellent. I have purchased grinz balls before. I have one dog who kills all his toys...but not the grinz balls. He has a red one that he takes everywhere with him. The balls are strong, the right sizes, and sturdy. It is rare for a dog to be able to tear them apart...the perfect gift for an active dog. I got the blue one, and the pink one in large for two Bedlington Terriers I know. I got a small green one for my little Corgi mix and a new blue one for my Jack Russell (to go with his red one).
