Francie bred Borzoi and yes she did just want a smaller version. They are all dna tested before you breed and were originally Sheltie Whippet Crosses which was then
selectively bred to small Borzoi, the difference is that the breed has been kept pure. Now, in the States they race and course them and believe me they do very well.
We have some racing for them here, they will chase rabbit or hare but you cannot chase hare round here, the farmers put up trip wires to stop it so, unfortunately it is
just plastic bags or furry skins.
