I am considering buying a dog for stud as i dont think my older bull terrier will be up to it when the time comes I can buy a lovely dog whos huge and a very nice tri colour wich is very saught after, the only fault there is with him is that hes undershot slightly !? you cant realy notice it to much because his lips cover it ! but when i pull his mouth open obviously you can notice it ! Should this affect weather i breed from him ! what i am trying to say is would pups that come from him allso be udershot ?? he is one huge specimen of a bull terrier for only 8months ! anybody know whats the outcome of breeding from him! thanks ****** .
