All mammals share a biological fact, we all have a front and a back. One Dogo vs one Bigfoot doesn't have much of a chance. Add to that if a Bigfoot like other dangerous game like Bears or Cats look for a defensive place to pick a fight. Such as a large tree or rock that they can back up to? It can be tough for the dog. And there are lots of those in the mountainous forested regions in which Bigfoot is reported to roam.
But by the time you get to four dogs, any time you even remotely square to the threat of one dog even with your back to a wall? You open your back up to a attack. If you hunt your dogs together they begin to work in concert, much like wolves, as a single enveloping entity. And that is just so tough to defend against.
I know this much, which is sad to contemplate, but even if the Bigfoot defeated all four Dogos? He would be maimed and bleeding and hurt and I feel would be easy to track. And it would be imperative to track and dispatch it because you wouldn't want that pissed off animal stumbling into a group of picnickers.
This would have to happen some place remote, but you could still bracket the chase and have flankers out ahead of the chase. It would be costly, and require a team of men.
I still have my yaggi antenna and collars, newer gps tracking equipment is also available.
And lastly it would be a horrible death for a Bigfoot, a death of a thousand cuts. I'd much rather take one cleanly or better yet find one dead naturally. But obviously the bar is set high for a lone hunter to be at the right place at the right time. Or canine friends are faster, tougher, more attuned to their senses and just flat give us an edge.
Of course with this comes tons of dedication, cost and man hours for the human master. Ultimately it's your dog and you are responsible to him to be bringing up the rear and find him if he is lost, hurt or dead. Many days and nights I just wanted a hot shower, hot food and a bed. But if you don't know where your dogs are you keep going......it's a bond.
