This is a fleeing apprehension bite and part of a PSA 2 scenario.

OMG: He's huge... I had no idea of his size in the jump picture you showed earlier.

And he comes up from behind too... opposite of where the weapon is.

With that size and weight, he could probably flip that trainer on his back in no time. LOL

I sure wouldn't want to be his trainer!!! (* CHUCKLE *)

FWIW

He is a long dog and is 26+" at the withers.  He got up to 130 pounds but was too heavy and he now weighs just over 100#'s.  He is very fast and agile for his size.  He is also a very well muscled dog, especially his pelvic mass, which I believe helps the hips.  His hips and elbows are OFA certified good/normal.

He is in training for our PSA 2 title and the weapon hand is a non issue in sport.

Chip is his trainer. PSA is a protection sport that is more difficult than IPO/Schutzhund which you’ve probably heard of.  It offers more realistic scenarios and you can’t practice for all of them so you can’t teach the test.  IPO allows people to bring along less capable dogs, although it’s still challenging and dogs that earn an IPO can be very well trained.   

When will you test for level 2? 

Even at 100+#'s, flying through the air, he could easily tackle most humans. (* LOL *)

FWIW

For each level, you have to pass  two times at two separate trials to obtain the title.  I will likely trial at our club's annual trial in September n Labor day weekend and then in October in West VA, where they typically have an annual trial. I don't like to travel long distances simply due to the hassle.  The West VA trial is only four hours away.  By training for another eight and a half months before trialing, I believe my odds are good at passing in two consecutive trials.

Here he is doing a courage test at the 2021 PSA Nationals.  You can see he was significantly heavier.
