There's good and bad in all crosses ,All sizes big or small. I've seen 2 beddy x whippets what on a open forum I ain't discussing what they could and couldn't do but there wasn't a lot they couldn't. We're they freaks or just given the right amount of work to prove there worth. I can't answer that but it's when you try and replace them like for like is you realise how good your dogs have been and how hard it is to get another. Enjoy what you have while you have it because you'll never have 2 the same that's for sure.
