We have 6 dogs,and 4 of them are Weimaraners, and they LOVE to retrieve!! our 6 month old puppy uses the disk every time we go out to the barn. He carries it to the barn,and he would have us throw it untill he dropped if we let him. The disk is wonderful as it is so easy for him to pick up and does not hurt his mouth when he catches it. Great toy!!!
