A dog has roughly 40 times the number of olfactory receptors than a human does. They can smell things we ordinarily cannot. And so, yeah, either something was wrong with that jogger or some wrongful smell was on him.I forgot to mention that we home school and I am home with them pretty much 24/7. I get along with most dogs, or maybe they get along with me, however you want to look at it. But I've met more asshole labs than GSD's. Non scientifically, our mutts all came from the pound, as puppies that tended to the older side and we didn't have many issues. Including the GSD mix. Maybe we just got lucky with dogs? Having said that I briefly considered adopting and I just can't take a complete strangers unknown dog into our home.
Hmm well this won't be a good look, but there was one pretty big oddball incident with our GSD mix as a kid. I was walking with him and he tried to rip a guys throat out in the park. Only time I ever saw him do anything abnormal. Guy was jogging towards us and the dog went from my right and shot up and over to my left in front of me. I dove right and jerked him away from this joggers throat just in time. Guy barely blinked. Just had a blank stare. I don't remember what I said or if I said anything, but I thought it was weird as hell that the jogger had nothing at all too say. I always thought after that the guy must have been a serial killer or something. Dog never did anything remotely like that before or after. 100% one off. We lived near by a big park and he had had countless joggers and bicyclists pass by him in the exact same manner. He never tried to bite anyone at the door or anything. Growled at certain people, which never seemed to have any rhyme or reason attached to it.
There is obviously more risk with a GSD than with a golden retriever. And also the golden retriever's I met while they were all super sweet I wonder if they would offer any wild life deterrence other than their scent. We oddly haven't crossed a golden off the list. I would feel a little better about my kids playing in the woods and being out of my eyesight in general if a GSD was with them vs. a golden. They are pretty much never out of my eye sight right now. Or at least they are not supposed to be. It's a constant battle. Especially with my 3 year old. If we are blessed with 10 years of companionship from a GSD I think that would be time well spent.
I won't sit here and say no other dog will be a good fit for us, but this does make a little sense. I really don't think I'm coming at this from a completely emotional and illogical view point. I'm certainly trying not to.
Other things are more individual. For example, most any dog works well as a drug sniffer. Some have the right temperment to do survivor and cadaver searches but they will need breaks because they can get depressed. I knew a few people who trained police dogs for K9 units. Not every GSD or even Belgian Malinois makes a good dog. It is a special temperment for a dog that is willing to bite and hold and then release. Some dogs just get scared and bite and won't release. Others won't bite.
