Rough dogs

I own 2 dogs one pit and one bmc (mears) bred.
1) i believe having the 2 dogs, sharing the same yard only got the bmc ruffer.
2) i also believe hunting 1 dog helps the ruff dog live longer = learn where and when to catch.
3) I believe genetics will be passed over from ruff dog down to its siblings however correct training when where and how is critical on how ruff the dog will turn out.
Think of it, I now i want my dog to stop a hog when its running however if you have a dog that stops a large hog by the ear in the thick stuff do you really think its that easy for him to let go and then go into a bay? its probably easier to stay latched on. Dogs that stop runners that dont ear the hogs that go into a bay after the hog has stopped are usually hammers or ballers which among must hog hunters are considerd week. My dog has stopped several larger hogs 350 and up running by the ear and then has gone into a bay, he also has bayed earless hogs that were in the 250lbs range but 95% of the time its 1 or 2 barks and caught hog. Im just saying when where and how the dogs get trained are probably just if not more important than the breeding.
By no means do i think im an expert but from my experience on the field this is my opinion.
