I was wondering if anyone else has a similar technique, or even the need for one...

I train alot of new "behaviors" with Sadie, and she picks them up very quickly. She is extremely confident, and trusts me pretty much completely. However, there are times when she will lose focus, hesitate at an obstacle, or otherwise get confused (such as when she gets too excited while tracking).
Long before I started training her as a working dog, I noticed something that helps significantly in these moments. When I adopted her, she wouldn't jump up into the full-sized pickup truck (she would actually cry and wait to be lifted). Well, I ain't about lifting a 55# dog into the truck, so I taught her to "hup" into the front seat, and later into the bed and over hurdles, etc. On a vet visit soon after that, I opened the door and gave the command. She wanted to comply, but wasn't sure about the height. I walked her away from the truck so she could get a little start, and she scooted right in with no further command.

Since then, I've noticed that circling her seems to refocus her, and it works in almost any situation where it is necessary to redirect her (such as when she loses focus during tracking, or I'm trying to divert her attention during desensitization).

Anyone out there with similar experiences, or specific techniques that work in any situation (besides the standard "stuff treats in their face" or "break out the tug")?

Yeah I second the turning.

For redirecting when he is severely obsessing:
I use informal heeling, I correct every move/look/intention get towards what I don't want him to get at. Every move towards gets a correction** and turn away from it. Calm behavior either gets to go toward it or gets to exit the situation and get a reward.

Just by body blocking and doing a left turn, you are sending a clear signal to your dog. That is often enough.

**fyi, very calm correction with DD collar for EXTREME obsessing (you have no idea lol) (this was done after exercise, some marker training and playing tug)....most cases one would just need a voice correction or light pop and "hey you, earth to dog" kind of correction.

Other techniques esp for Mals, Dutchies...jogging instead of walking to emphasize a "leave it" without correction or reward.

You have to be fast for this but when you dog tries to jump up you can put your hand on their head and push them back down or in the case of a very manic dog, step aside as they leap and put your hand behind the head on the side of the neck...then spin the dog around. Momentary confusion, quick throw a ball LOL

Small watergun works on some dogs. Logan HATES it and I used it before, worked great as correction for not sitting and stuff like that.
