The more I read, talk to experienced dogmen and learn, the more I realise that as long as the basic material is there the mix is only half of the equation. The time and effort you put into the dog will dictate just how well the dog turns out.
As it turns out, my bull x is probably a bit ott just for bunnies and general duties, but I reckon she'll do well at what ever I train her to do.
