It could potentially influence any dog (such as the one that was washed for being too defensive. The only training she ever got was SAR training.) and partly goes back to having a temperament suitable for SAR.
Please correct me if I'm wrong because I don't have background in training for bite sports, but when you're looking for a good candidate isn't it an asset for the dog to have a strong defense drive? Does it vary where some dogs are running off strong defense and others going off play/prey drive? Or is it some combination of the two? I would not consider a dog with strong defense drive to be a good candidate for SAR work. Strong play/prey drive is good though.
For starters I don't really like to use the term "defensive drive"
I've come across too many definitions for the term to find it useful for myself. To me, "defensive" is a part of "fight or flight" when flight isn't an option. When I think of drive and a lot of some type of "drive", defensive isn't something I want. Strong nerves to stay in a fight? yes confidence? yes, the ability to discern threat from non? I like a moderate threshold for that myself.
In an ideal world, any dog would instantly know any "real" threat from one that isn't, but none of us live in that world. But i've seen dogs with weaker nerves described as having great "defensive drive". To me, they have low thresholds and too many things are threatening to them. That doesn't mean it's a horrible dog, they can be great depending on the use, SAR definitely not one of them
But then they wouldn't be good for SAR regardless if they had bite training or not.
I also don't debate as to which type of dog is best for work, because a lot of combinations of nerve, drive and thresholds can all make for fantastic working dogs. A good friend of mine always said, " I never heard a bad guy say, That bite didn't hurt, it was only a prey bite"
and it's true. Some of the most badass dogs I know will bite you purely for "fun" They have great active aggression, because of how it was trained, but their nerves and drive are so great not much is really threatening to them.
I prefer those kinds of dogs, one I have zero need for a dog with a hair trigger. and if there is a threat, I can activate them on it because of our training and I know they are just looking for a chance to bite because they love to do it. It's fun and mostly prey.
If I don't activate them on it, they'd have to be one incredibly threatening person, making overt attempts and hurting me or my dogs to get much more than a watchful eye.
Anyway, that probably makes things clear as mud huh? But I agree, any dog that reacts easily to a "potential" threat, probably isn't a great candidate for SAR regardless of bitework history. But there are lots of variations of dogs that are great for sport or work, they could handle SAR with no problems from bite training.
If the dog has a history of being involved in bite sports, that is an awful lot of ammunition to hand a litigious person in an already crappy situation. I suspect this is a big part of the reason why many groups do not allow dogs who have been involved in bite sports.
Add that to situations like my friend had with the K9 attacking her at a large and well attended regional event, people come away from that with a very bad taste in their mouth about the compatibility of SAR and any kind of bitework.
Even just training and not being on the search team, the other team members don't want to risk being injured themselves if a dog gets too defensive.
I agree that it is a problem in general in any society where those with the least amount of knowledge seem to have the greatest and loudest opinion on something and influence those that work for the deepest pockets and make the rules, I mean the politicians that work for the people
But it is like that with everything it seems these days. One the surface, a dog with bite training would seem like a bad candidate to go out and look for people to those that don't really understand what's happening. All that really matters is, Does the dog posses the qualities of a good SAR dog, and then train accordingly.
If it does have those qualities, training bitework in the context of sport shouldn't have any effect on it's search work. It's so contextual that a lot of that training wouldn't even come to mind in a real search situation for the dog.
The difference in that is your example of the police k9. We do a lot to broaden that context for the dog. Some of that includes, long tracks over varied surfaces where they are confronting a "bad guy" at the end. If your bitework training consists of scenarios like that, well don't be surprised if your dog reacts like you trained it to
But in the context of IPO? its a directional send to a blind, very contextual and if that's where you keep it, you can have a great competition sport dog, and one that is as safe as any other in the field for SAR work.
But those with the least amount of knowledge do seem to have the greatest amount of influence these days.
I used my patrol and drug scenario earlier in the thread, but another one is an IPO 3 and has done SAR work, but now is a FEMA certified urban and rubble search dog.
I was his helper for IPO on weekends and during the week when we'd do Police dogs, He'd come out for his search training and I'd be hiding in all sorts of places without equipment and I'd toss balls for his rewards. Because he was more of a urban and rubble dog, he barked at finds. I was buried sometimes, so it wasn't go find, and go get the handler, it was find and bark.
So we have a dog that was sent in to bark and then bite me in sport training, and in "real life" training was sent to find me and bark, but not bite and I never felt in any danger from that dog. You can tell what a dogs intentions are after you've stood in front of enough of them. He understood perfectly what was going on. When he found me in a blind, he was looking for a fight and to bite me. When he found me on searches, he was looking for his ball to be thrown.
He wasn't being sent out a mile away from his handler either so the handler was nearby to remind him of his job and the search areas were definitely more contained, but a very good SAR dog none the less. But he was also tested thru that in certification as well so it was no surprise how he'd react either and in the end that's all that "should" matter. but what "should" be rarely is how things are.
If you live in an area with no underbrush and good visibility, that would probably work. Around here. . . well, I'll dig up some pictures I took of Charlie in our grazed pasture and you'll see what I mean as far as terrain and plants. In most places you're searching for lost folks you maybe have 5 feet of visibility around you. Anything working on lead gets so tangled they're literally useless. The only time I've seen the formal tracking team called out is for evidence searches where they've got a smallish established search area and are looking for things like bone fragments. I've never ever seen them called out on a live search.
They don't necessarily need to be on lead, just within visual and voice range. I'm confident any dog I've done bitework with will NOT bite someone if doing a different task, especially if I am there to remind them of that task with a simple verbal of what they're supposed to be doing. No matter how threatening or confused a find may be.
However, that is considered extremely inappropriate and no reputable service dog training organization would ever in a million years consider training a dog that has done bitework of any kind.
I know a couple that have
National Association for Search and Rescue has and SUSAR.
