if you want to get a pit or any other big assertive breed, you first have to ask yourself what kind of personality you are, if you are timid, shy,quiet, etc, a pit or rotti, big dog in general is NOT for you, as has been said, dogs are pack animals and they will test you on where they stand in the hierarchy of the pack, if he feels your not standing up to your end of the bargain of being boss, he will show you who is, i've had big dogs for 25 years, everything from mastiffs, danes,sheperds,labs, they need a leader, last thing you want is a 125 lb dog ruling the roost.
