Every pitbull is unstable

sorry, can't think of a nicer way to put it- you are a fool.
I've owned many dogs of many breeds, and by far pits are the most stable and predictable, when raised in a stable environment. the only unstable ones I've ever seen (and I've seen hundreds) where owned by unstable people, or wimpy guys who thought owning a tough dog would make them tough, but didn't know the difference between tough and mean.
I've had my current dog (pit/chow mix) for about 12 years. got her when my youngest was 1 yr old. never any problem with unnecessary aggression. never any problem with her not using necessary aggression when the situation called for it.
when raised to be a part of your family (not some toy to take out once a week and impress your friends with how strong his bite is or how aggressively he will attack a lure or other dog) they are IMO the perfect dog to have around children. they will let babies chew on their ears, and use them like a climbing toy and never growl or snap, they can tell the difference between an intruder and a visitor. and they can tell the difference between someone attacking your kid and kids rough housing around (something few dogs can do, you wont fool most pits by having someone pretend to hit you to see how they react, but if the situation comes up for real they are there right now.)
my dog greets everyone who comes to the door with a friendly wagging tail (only exception is she doesn't like cops, my opinion is they put out an attitude that they are in charge and expect to be obeyed, my dog sees this as my house and thinks I'm the only one who should be obeyed). if she is out loose and meets you in the yard she will be extremely friendly.
however if you enter my back yard by climbing a fence. she will run up on you fast without a sound, until she is close enough to nail you, then she will bark until I come out, or if you move she'll attack on her own. the exception to this is children. she just barks immediately and non stop from the time a child who doesn't belong here reaches the top of the fence.
so far she has actually taken down 2 intruders (one inside my home and one stealing tools from the shed). and as I said earlier never an unnecessary aggressive moment, she doesn't even require tranquilizers when the vet trims her nails(most large dogs do), even though she hates it she just whimpers because she knows I wouldn't let them do it if it wasn't good for her.
I never trained this dog (other than your basic house breaking, leash, heal, come, sit, stay) pitbulls will take to these behaviors naturally just like any decent person would feel about protecting his family, and her behavior is not at all uncommon for pits raised in a loving home.
There are only 2 reasons why I don't own a full blooded pit.
bad publicity making people call the police every time your kid leaves the gate open and the dog walks to the front yard.
and she is primarily a house dog in the winter and chows are amazingly clean, but pure bred chows are generally too high-strung to be around children.
btw- the pit in the picture looks to be about 1/8 to 1/4 boxer. good looking pup though, got a pic of him standing?
