how many dogs do u need/have the work for?

I try to hunt at least 2 or 3 times a week it is hard for us up here to get on a bunch of pigs we have so many deep canyons and such! I have a 2 yr old bmc male that out strikes my 6 yr old finished dog 99% of the time he is very much trash broke! He struck his first boar off the hood at 11 months old over my old finished dogs this pup has no quit in him he gets on a track he will either shut it down or u will have to go pick him up I run 2 bay dogs and 2 bulldogs sometimes I wish I had more on the nasty runners in the thick canyons!
