[quote=RealdoggeSyndicate]The size of the head has nothing to do with the hardness of the bite,coralation of bite has to due with symmetrical skull and jaw confiquration.length of muzzle creates harder bite due to sissor bite and leverage in bite design.I.E. an overly long snout with a small head or an overly large head with a short muzzle does not insure a greater bite. just as people beleive that pit bulls have a locking jaw not the case,its hardness of bite thats all.................thats why there is bloodlines with in.. Realdogs[/quote] so you say the size of head has nothing to do with it, then you say a dog with long muzzle and "SMALL HEAD" will not bite that hard.. and presas dont have a long snout, but renowned for massive heads... their bites are VERY hard... Tosa has a decent length snout and a big head but yet has big bite. kangal has a LONG muzzle and a big head and again... a big bite.. american bulldogs have a short muzzle but huge head and again a BIG bite! wolves have long! muzzle but big heads and again... big BITE. its a dead obvious fact that bigger the head is, the more jaw muscle it has and the bigger the bite...
