Typically a "Drag leash is for use indoors and kinda short?? If your using a "Drag leash" out doors?? It should be 15 feet or so and it's best "not" to actually let the dog drag it! They can get a lot of speed up fast wit the longer leash and if that leash gets caught on something ... that's not good!
I can almost guarantee you that if you are using a 6 foot drag leash outdoors ... if that dogs decides to move fast ... you won't be able to stop him! Having a dog always on leash outside ... is a "PIA" but if it's a dog you just ?? You have no choice!
I've always trained "Stay and Down" first before letting my dogs off leash. Boxer thing "recall" takes to much "processing" ... the dog "thinks" ... I must first stop doing whatever it is I'm doing ... turn around ... and come back??
Stay worked much better,it will slow them down and "Down!" Keeps them where they are! You drill,drill Stay and Down, Down and Stay and then the dog has "nothing to think about. It's more like "oh ... I know that one!" And "boom" they "Stop!"
Fear or Aggression ... the "pro's" will tell you (I know becasue one told me.
) That JQP cannot really "distinguish" between the two??? OK then fine ... I'm not a "Pro" so I choose the term "unpredictable??" As I have no idea what "this dog" my best course of action is "to keep people out of his face!" Ie "Who Pets ..." but if you look close ,,, you will see that "Who Pets ..." is pretty much the same thing as the "Five things to do with a fearful dog article!
" I don't know that the "banquet" thinkgwould be that great an idea ... right now???
I have always followed the "Leerburg Protocol" "Who Pets my Puppy or Dog" except with my Boxer and Band Dawg the answer was always "to my pet" please do! Worked out fine."
But when I got my first OS WL GSD ... I got pretty clear indications early on that saying "yes" ... might not work out so well?? So I decided that well ... you know .. .what if I say "NO??" Long story short ... worked out fine and when I happened to get the opportunity to work with an "acknowledged true fear of people Boxer ... I did the exact same thing!
That was working so well in fact, that with him I had abandoned the step in front of my dog approach! The dog was actually between me and people .. (I did not do that with my GSD) I would stop at about 5 feet away from people and "Rocky was behind me but this dog was good at that distance only with the person to his outside and nme beside him. And I'd answer questions about him and we would move on ... no problems.
If the story ended there I would have said "this dog does not have people issues and ... I'd have been wrong! As it happened ... as we returned to camp, yet another person stopped us and asked about this "Boxer??" We are of course 5 feet away ... as I contemplate an answer but ... the woman steps forward ... she closed my five foot gap?? The instant she did ... the dog stepped back and presses hard into my leg??? I look down and he looked up at me and his eyes were big as saucers!!
That was it "Fear of People" confirmed! My hand went out and I said "NO!" Fear of people we are in "training" And we were out of there! I did "Sit on the Dog" with him back and camp and to amazement this dog that I had seen the following week and he just looked beat down ... although he could not move beyond the 6 feet leash ... he appeared just as happy and goofy as all the other Boxers?? And to my astonishment when I went back I had expected to be working with him again ... but he was gone as he had been adopted.?
The "banquet" think ... I don't know just yet?? Someone mentioned the "term" flooding the dog, as I understand put so much pressure on the dog ... that he has no choice but to give in?? In "extreme" circumstances sometimes yes that is "necessary!" But here don't know ...it may work out fine?? But I'd ask ...what's the hurry???
The way dogs get over this crap is by them having faith in you! "Mommy's"s got my back as it were! But if you push to hard to soon you can break that trust??? If you want to try what your suggesting the "Banquet" thing "now??" Simply do more of what your are already doing now! More "Place Training" and more "Sit on the dog" out and about not "just" in the home?? And more walking and finding people to ignore!
You seem to have this handled ... just don't expect ... to much ... to soon and the dog will be fine your building a "Bond of Trust" here and that takes time.
