Preditory Drift

 Well, the white dog would stand out, from the contrast between it and grass/trees/asphalt.

Personally? If there was ANY chance the he might kill another dog, I'd muzzle him. Who cares what people think? Of course, I'd get an appropriate basket muzzle, and TEACH him that being muzzled is a good thing. It'll probably serve the dual purpose of keeping people with small dogs at a distance, AND protecting Bourbon from being involved in another attack.

Oh, that is just terrible. Having a pit myself who can be aggressive with other dogs, I would also say muzzle him whenever he's outside of your house or super-secure, fenced yard.

My dog Rosco has a very quick trigger, so I totally understand how hard it can be and can't imagine how upsetting this must be. We also use a harness because it gives us the best control. He hates dogs who carry their tails over their backs, so that's his easiest trigger. It's taken a lot of work, but he has a solid leave command and always gets rewarded for paying attention to me when other dogs are around (vet, walking, or any place). He'd rather work for food now than focus on the other dog.

And, if you haven't already, work with a good, CPDT trainer so you can learn new tactics for management. As a result of the attach, his bite threshold will be lower, meaning he will bite again, and possibly with even less hesitation, given the opportunity. The worst thing would be something happening again, and your dog being PTS as a result, or a breed ban that would affect everyone in your town who has a pit.

Good luck and keep us posted. 

My dog has a pretty good prey drive and you can do several things about it.

-You are free to consider a muzzle BUT the real danger is to avoid him getting so fixated that he will one day run accross the street and will get hit by a car (a muzzle wont prevent that)

The trick is to TEACH him that prey drive is not allowed on the walks.

-I would change the harness for a British style slip lead, just like a chain collar but it wont hurt the dog and is designed to never slip out

You will need this type of leash to TEACH the dog not to go after small animals during walks.

Now here comes the real exercise and i did something similar to this:

I didnt buy a rabbit or put my dog on the floor, i just corrected my dog out of the fixation every time the behavior was coming out. The thing you have to watch for is when your dogs direct his ears towards the small animal, thats when you redirect, if he keeps looking at the animal but his ears are to the side thats ok, he is acknowledging but the prey drive is not there. Dont wait one or 2 seconds after, it MUST be right away.

This technique might have saved my dog's (and other dogs) life more than once. I tried to use food to redirect but my dog's was taking the food and going back to redirect his pray behavior. There are times that the rabbit just pops out of a bush and the prey drive goes from 0 to 10 in less than a second, at that moment there is no food that can compete with that. I was not whilling to risk my dog's life with something that for me was having a high rate of faliure while i was implementing it, it only takes once for a car

This way you are teaching your dog that chasing small animals is NOT allowed during walks.

I dont try to extinguish his prey drive whatsoever, i actually use a flirt pole with him at home and he LOVES it, here it's a video of someone using one:

This way you are exercising his prey drive in a good way where everybody is safe. My dog knows the difference between doing it at home and during walks.

This is what worked for me. It works great, this is the best technique for me and my dog.

 Pit owners need to be aware that their dogs have been bred for generations to be dog aggressive, and when they are, they show little warning, which is why so many of them end up as statistics.  Your dog, regardless of whether it was showing predatory drift or just plain old dog aggression, is typical of the breed in the sense that there is usually absolutely no warning before the event.  This breed is often prone to have the "switch" go off unexpectedly, and it really isn't "all about how you raise them".  You were correct to keep your dog out of the dog park after the incident you mentioned, but, frankly, Pits should not be in dog parks anyway, because there is just too much potential for the unexpected to happen.  And, every time it does, someone else proposes BSL.  I do blame the kennel - they are undereducated about how you restrain and walk dog aggressive breeds - because in the kennel situation you must assume aggression is possible, doing all in your power to prevent it from happening.  No large breed dog should be out in the area where there are dogs less than half the weight of the larger dog.  If owners want their dogs to have playmates that differ greatly in size, then they can choose to put their dogs in that situation, but the kennel should not. 

Pits are not the only breed with dog aggression tendencies, but they are dangerous because of the lack of warning.  Other dogs often freeze, posture, stare, snarl, growl, etc.  Pits go from 0-60 in a flash and that's why their attacks are often characterized as "unprovoked" - when, in actuality, it was the mere presence of a dog or prey animal that triggered the attack (and interference with the attack sequence is usually when humans get bitten).

At any rate, if I were the owner of the small dog, I would be suing the kennel, not that it would bring the dog back, and I would be asking not for money, but for mandatory education for their staff.  

what is rescue group exactly

I have a pit mix she don't look at all like a pitbull just has brindle stripes but she has learned to be aggressive to ppl and animals outside the family

been wanting to take her to a pit rescue and see if any knowledgable volunteers can/willing to work with us

While rescue volunteers are great resources of knowledge, you would be far better served visiting with a canine behaviorists for your dog's aggression issues.

tfsm,

being aggressive toward people outside the family is not a characteristic of the bit pull breed. Something else is going on there.

In general, this is true, as a breed characteristic.  Pits were originally bred to work well with humans, but to be aggressive toward other dogs.  I agree with Bevolasvegas that you should seek help from a behavior pro.  You can find one on the IAABC web page.
