Intact Males fighting- advice- nut 'em?

Hello all,

I recently picked up an intact male hound, and took him hunting with my other dogs yesterday- hounds and one bulldog. The bulldog was muzzled, but they still got in a number of fights. The bulldog is game, so the consequences of these fights could have been pretty severe. The hound gives pretty good too. I don't want to get hurt breaking them up, or for them to get hurt worse than they already have.

I have experience with high-drive, gritty hunting dogs, and have had decent success hunting other dogs together in the past. Each male does fine with my other dogs-2 intact females, 2 neutered males- hunting and loose in the yard. Right now I keep the two males separated in kennels, but I would like to be able to hunt them together, as well as have a little piece of mind that if they get out and meet in the yard they won't kill each other. In the past, I have taken this bulldog and gotten him to live with neutered males that at first he fought with.

If you have experience with this subject, I would appreciate advice. I would neuter one or both if it would help.

Thanks
