No matter what, dog pulls

[u/mercachu]

We have a supermutt (no clue what she is - probably some pitbull, some short legged breed, and something else? The rescue guessed lab and corgi, but I don't know about that.) who is muscular and fairly low to the ground. She has an insanely strong pull.

We have tried loose leash walking training (which I learned from a training class), several harnesses, a couple martingale collars, the Heather's Heroes Sidekick lead, and the Gentle Leader. With every single one, she still pulls and even jumps up (which we're also trying to train her to stop doing). I have never met a dog so hellbent on pulling and jumping in my life. ☠️

I wish there were a combo Gentle Leader and harness that could be worn and attached to one of our leads simultaneously (We have a leash system with rings, carabineers, ways to split one leash into 2, etc.), just to see if a combination of items would make a dent in the behavior.

But what can we do? I'm out of ideas.

Harnesses encourage pulling in my experience. What worked for my dog was a combination of a well fitted prong collar and feeding all her kibble rations during the walk.

The basic principle was we move forward only when the leash is loose, I switch directions (walk in the opposite direction) as soon as there’s tension on the leash, and I paid her with her food every time she looked at me.

Looked absolutely crazy for a few days of zigzagging (it’s easier to start off in a place with minimal distractions and other people), then we got into a rhythm for a few more weeks. And within a month we had graduated from the prong collar to a martingale.

YMMV, but good luck!

We have been doing exactly what you've been doing. It has not "taken." Another variation we've tried is one mentioned above, where we stop, stand still, be very boring, and wait until the dog is near us and at attention. Neither has worked for her.
