yeah and sharks arnt born vicious either
dobermans , pitbulls , staffs etc are all instinctivly vicious animals but their owners will all say how soft and gentle they are then look everywhere for an explination as to what went wrong when the mutt decides to mame their or somone eslses child
if you got a child and must have a dog get somthing that cant fit its mouth around your childs throat and maybe just maybe the poor kid will stand a chance if or when the dog turns on it
an old friend of mines parents had a doberman and in the summer it had to have a hat on its head because apprently they have thin skulls and heat sends them vicious , some kind of sunstroke or somat , why anyone would keep a dog like that as a house pet i dont know , keep the vicious dogs for guard dogs but not as a childs pet
