Get a picture up :)They will enter on quarry very young, but hold them back till about 16-18 months, they mature fast, like every pup make sure its fully stock trainned before taking it out for a hunt:) they tend to hunt up so recall must be good as they are a terrier breed,,, they must be keep extra fit or else they will have no stamia as stamia isnt a strong point in the bullx they over heat, prey drive is brillant and brains are ok depending on the dog of course but build a good bond with it and you will never take on any other cross ;)they have balls of steel on quarry. atb with him
