I am sure your pit would destroy much larger dogs, like labradors, probably even dobermann and rotweilers.
However it would not destroy something like a dogue de bordeaux or japanese tosa. They are tough as hell and much bigger."
I honestly believe that a fight between a fully grown snakehead and a fully grown dovii or jaguar would work to the snakeheads advantage because of their styles (lip locking vs darting in with quick strikes). I don't discount what others are saying about cichlids because frankly I haven't really raised them. I've seen a jag that was brutal and managed to survive in a redbelly tank (pretty smart mofo).
I do love my snakeheads and the aggression that they display, but I have to admit that they have a tendency to be backstabbers towards other fish (waiting until the other fish turns around before striking), and once it has the other fish on the run it's pretty much the tale of the tape until the sh kills the other fish or until the other fish dies from stress.
In my country we have videos of pits vs tosa's and large mastiffs like bordeaux's and working rottweilers, and none of them can trump a pit (sorry to burst your bubble). Not that I condone animal fighting, it's just my dog of choice has always been a Pit because their loyalty and drive to please their owner is unmatched, and coming across these video's I couldn't help but watch.
If you understand how the winner of Tosa fights are determined (kind of like high school wrestling with points for takedowns, etc.), and the average japanese persons aversion to alot of blood you'd understand (this shows in alot of their horror movies as well which creates it's horror through tension rather than pure gore). Tosa's are good wrestling dogs, but Gamebred Pit's can withstand alot of punishment, naturally have better endurance, as well as stamina (they get their second wind really fast, their recovery is amazing) and know instinctively how to expoit an opponents weakness. Versus bigger dog's (in the videos I've seen) they usually latch onto an ear for defense and ride it out till the other (bigger) dog gets tired(they are savvy when it comes to this), and dish out punishment appropriately. They just don't bite wildly like other dogs either, Pits really pick their spots to work their hold.
I couldn't imagine putting my dogs through that though. I just want to know what evidence you're basing your statement off when I quoted you? Since that statement has no basis, and you can say it so casually like it's fact, it makes me wonder about all the other stuff you say.
