a friend of mine has got a rottie x greyhound from an accidental mating and in his day he was a grand dog , mustard on foxes and as bosun said hed retrieve them back to you smashed to bits, he was a good deer dog as well, rabbits were his daily play thing he was always catching them in short hes a clever dog hes about 14 now and still willing he just wont exept the body s lacking but hes still very alert, id say if you have the time run them on and see they just might surprise you!
