This was to replace the one that is in the North Sea somewhere.... Because of the colour and whistle it's easy for my dogs to see and retrieve... should have got a medium as the large is a bit on the big side!
I love these balls and so do my Dobermann's Xena &Kali. They have lasted much longer than any other ball I have bought for them. I believe this is because the balls don't have a seam in them. I would highly recommend, in fact I have already done so on the Dobermann UK Facebook forum. Well worth the money!
