i have a deer/ grey and he turns great for the size of him. i walk my deerhound grey with me mate and he has two whippets, im sure they have taught him to turn. hes quite good on the bunnys and most things i point him at. hes great i take him everywhere and he goes on what ever hes pointed at. hes not fantastic at everything but he will have a good go. like i say im happy with him. he does what i want!
and if you really dont believe they do rabbits with ease, theres a dvd on ebay and the first twenty minutes is full of deerhound crosses smashing rabbits! i will get the name of the dvd u
