my bitch, when a pup, had a stage of ignoring the recall,after reading a fantastic book on lurcher training,i tried a method explained in the book,
basically the dog knows it can outrun you,and of the lead you have no way of getting it too come back too you if it doesnt want too,get yourself a catapult, take her out,arm yourself with some ammo,such as acorns or balls of mud, let her of the lead and try calling her back,before she gets too far away,if she turns a deaf one,without her facing you fire off a acorn/ball of mud,if this hits her she will then realise you can reach her at distance,ev
