RE: Guard Dog anyone? *pics* they go cheap I hear...
John,
PitBull vs. Tosa is for the most part speculation, at least in the US. Essentially, there are no "real" fighting Tosas outside of Japan, as they are so highly prized. The Japanese, however are VERY fond of American Pit Bulls, and use them for training their smaller Tosas, and use them as their primary fight dogs too, but in the lighter classes. The APBT possess huge amounts of gameness, and are quite quick. Although the pitbulls are faster, it wasn't able to grab onto the Tosa sufficiently to injure it greatly.(remember, small Tosas are 75-100 pounds, larger than most any APBT, although there are exceptions). The Tosas neck was far too large for the pitbull to grab onto properly, and beacuse of it's huge neck jowls/rolls, when the pitbull did latch on, it was only skin for the most part. The APBT was able to break legs with bites however.
There are different styles of fighting, and each dog has its place. In the traditional fighting, the Tosa is king. This is a fight of raw power. The dogs aren't allowed to bark, whine or growl. If they do they lose (seri). Also, if the dog turns away more than 3 steps, it's also a loser (hashiri). Most wise APBT owners in Japan won't gamble stepping their dogs up in weight too much. A nice sized APBT at 75lbs would be ruined by a 200lb Tosa. Although APBT are super game, weight does matter. I mean the Tosa is over 30" at the withers. APBT are much, much more compact. You really have no idea how completely massive a 200lb Tosa is, unless you've seen one. (a 200lb man is big..imagine that 200lbs on a 32" tall frame...LOL)
They also fight the traditional Western style fights (scratch and turn Cajun rules). Most Japanese prefer APBT for that type, for their speed. This is the style of fights held in illegal US dog-fighting.
When Japanese dogmen are asked which dog they would use in a "no hold barred" type fight, they ALWAYS pick the Tosa because of its massive size. In all seriousness, it's really asking alot of a pitbull to tackle a huge 200lbs dog that is TRAINED TO FIGHT. It has been documented that pitbulls have killed bears and bulls and such, but those are the exceptions and not the rules. Top notch pitbulls have been felled by Dogue De Bordeaux and Presas, mainly because of size.
Also, only those with LOTS of money fight dogs in Japan. Oddly, it's VERY illegal to bet on the dogs, and stiff fines and banishment can happen if betting occurs. Also, these guys pay memberships to dog clubs. The fights are VERY organized. Here's the best part. Any dog that shows aggressiveness to people must be destroyed. They take it very very serious if a dog is vicious to people. People killed by dogs in Japan just doesn't happen...it's very very rare.
