I breed Bull Terriers & Jack Russells in US. In my experience, the pet owners want a Bull Terrier with more Bull in it, calmer and a good companion for family so they breed out the gameness in the dogs. As far as looks go, I like a good Bull Type Bull Terrier, lower to ground, wider chest, big head etc. Something to show off at the pub etc. However, my dad is a mad hunter and we have one Bully girl who is very game. She is more terrier type. We use our russells to go to ground for groundhogs, armadillos, racoon or whatever and bring a Bully along to pull the animal. Non of this is illegal
