u/unlicensedpharmacy

I really want to get into bite work or scent work I don’t know if it would be good for both but I definitely want to at least take part in one. The problem is I have a bullmastiff and is quite stubborn and huge to lug around everywhere, I was thinking of just getting a pit-bull as well to run with etc so my big question is would a pit do good with nose work? I know they do well in bite work but I’ve been leaning towards nose work and just have a love for pitbulls and don’t know if they are the best for nose work.
