tl;dr
jk
While the relevance of your former use of the term tl;dr seems irrelevant at this point, I am forever trying to expand not only my actual knowledge of vocabulary, but also my internet vocabulary, so if you don't mind my asking, what exactly did you mean when you said tl;dr?
On the break stick and the websites: I mentioned I'd never heard of them until this thread.
I could be wrong, but I'm fairly sure that you are the one who has credited themselves with being a veterinarian. It really surprises me that you could go through veterinary school, let along however many years of practicing, without hearing of a break stick. No offense.
I did google them, and they appear to be suggested by a few Pitbull "fancier" sites, and they appear to be reputable sites dedicated to the breed.
I have been affiliated with both groups that are affiliated with the breed both on and off line. I find that especially online, you are more prone to bad information and to groups/individuals that uphold pitbull myths though claiming to be advocates for the breed.
My personal thought on them is this, if I owned a Pitbull, and I was training it to grab and hold something, like a rope or a toy or perhaps another animal, it's then and only then I'd consider having one.
First of all I'd like to point out that there is a huge difference between the options that you gave. Teaching a dog to hold on to a rope toy and not let go is a game that many dog owners like to call tug. While they may eventually let go due to lose of grip or lack of strength, it's still a natural game for dogs to play. It derives from the biological need of wolves to fight with other pack members/other packs for their food. That need to tug is still present in the modern day dog. Let's assume for a second that you are speaking of an assailant or someone who does not belong in the dog's normal habitat (as I know this specifically was an issue earlier on). If you have trained your dog to attack invaders, then you would not/should not leave your dog outside unattended. This has nothing to do with breed, but rather responsible dog ownership, and especially responsibility that accompanies such training. As for your last example of animals, dogs in general are prey aggressive, anything they perceive as prey, they will chase/hunt/etc. This especially true within the terrier breed. They are bred to hunt small prey (even though in some instances the prey may be larger than the breed itself). As I stated before, I am currently also living with West Highland Terrier that belongs to my fiance's parents. She (a major runt, standing only 6" tall [being generous], by 10" wide [a rough guess]) Not only bosses my APBT around, but also shows more of a perpetuity to harm smaller creatures than my own dog does. This is not merely a "Napoleon complex", but rather the terrier in her coming out. She is specifically bred to go into small places, and more specifically underground, to trap and/or catch rodents. Even the AKC website says that these attributes are typical from terriers ranging to the size of West Highland Terrier, like Cottie, to the size of an Airedale Terrier. While an Airedale Terrier may be slimmer (as in less muscle mass than an APBT), they are still as tall as an APBT and they still possess the same personalities to go after other animals, including dogs and cats. This is not an attribute specific to APBTs or other bully breeds, but rather to the terrier group as a whole. I truly defy you to find a website that recommends a bite stick for any other terrier breed. The idea behind a bite stick rests behind a more than proven myth. Not to mention that APBT or APBT mix owners go above and beyond to socialize their animals, and to help others socialize their animals (especially in the case of adoption).
That's the feeling I get. And I say that because a lot of people I know that have had Pitbulls haven't been the best trainers. They encouraged the dog to be aggressive, but only so much.
Encouraging aggression in any breed of dog is a bad idea. Number one, you want your dog to be sociable. Number two, you want to avoid aggression directed towards humans or human directed violence (which occurs when an animal is unable to defend/attack a perceived threat and redirects that focus onto the handler), This type of behavior is either due to lack of corrections or due to praise when certain unwanted behaviors have occurred (rather consciously or unconsciously).
They want that dog that could tear apart another dog in an instant, but only when they allowed it.
Outside of someone who is training their dog for the purpose of fighting, I know of -NO- dog owner who wishes this upon their dog in any means what so ever, not even when it comes to defending themselves against an attacking dog.
As long as they were present the dog was OK, but it gets out, or off the leash and then, like the last poster said, every cat in the neighborhood winds up dead. Then they say "Oh, well that never happened before".
I could make several comments about the last poster. First, was the dog actually a pitbull. The sad fact about bully breed owners and bully breed mixes is that they don't actually know what kind of bully breed they have taken on. This means they don't know what needs to fulfill. Second of all you are right when you follow this comment up with the fact that dogs don't snap for no reason. Often times it is something that the "victim" or the owner missed. No dog attacks without giving warnings. It's biological nature not to want to put yourself in harms way unless you feel it necessary for your life.
I'm sorry, but I've been around dogs, and they don't "suddenly" turn unless they are hurt or they have distemper.
As I said previously, you're right, dog's don't just turn. However the reasons for them to "snap" are various (regardless the breed of dog, as I have demonstrated in my previous example). You simply list two of the hundreds of reasons that a dog has to snap. Most commonly it is because they have let their dog feel that they are in control of a certain possession or aspect of daily life. If a dog does not feel they are in control then they have no reason to snap. When it comes to dogs, you have to look at them (even though you may view them as your kids, family, etc.) as dogs. You can't analyze their behaviors as if they are humans, you must rather look at their biological needs and desires and find a way to fulfill them in a way that does not encourage or elicit "bad" behavior.
Otherwise there's always some sign of aggression.
There is no otherwise, there -IS- always a sign of aggression. Unfortunately, often (regardless the breed) the warning signs go unnoticed. Even if someone manages to notice the warning signs, they have no idea what to do when they are presented with one of these signals. So I highly encourage you to explore the possibility of ignorance (as with any breed), before you buy into the myths and victim stories of others.
