I doubt many on here would know what a Pitbull was let alone a Staffordshire Bullterrier, Beauty is what beauty does, now not many of the wee dogs being posted on here do anything but look pretty, so what would you gain from adding this blood to a Lurcher???
Theres Lurchermen length and bredth of the country breeding tried and tested Lurchers, best to best, some have a lifetime experience in doing this and will sell you a pup for a bag of rocks (if you have good intentions).
The Kennels are full to the brim of abused Staffy crosses that have mixed temperments etc, why add to this??
