Must be a professional then?
Transversely, i have seen a pure Doby bitch working fairly well, obviously it was no threat to a working lurcher, but she done fairly well on the lamp She was a well built wee thing, kind of like a whippet grey cross type, very lithe, You never no mate, might work out for you.
But i wont have a dig, i'm no professional
All the best,
