Oh yes she does.
A little advice please? How can I get her drive up for the tug? She is still more interested in going after the poor decoy than the tug toy- she won't "hold" on to the tug she bites it grabs it then drops it and goes after him again. I have a tug at home we play with- she is more interested in getting it from me and playing chase, she does love to tug with me.. The first class we did bitework in, I didn't have her crated until right when bite work started, then I crated her. They have had me crating her since then- I thinks she "burns" our before we get to bitework cuase she has a tad bit of SA and barks almost the whole time she is in the car. We just started working with an E Collar today as well.
After she wins the tug...cradler her by her lower chin and gently stroke her so she'll see that holding(not chewing it) is a good place to be. Only reward(let her win) if she has a deep bite on the tug~let her counter to bite deeper before you let her win. Again, cradle her, stroke her with quiet praise and then when she outs(don't make her out in conflict*) do it again, but end it before she tires of the game.
If she is shaking or thrashing the tug, you need to calm that down...the helper work will help her transfer her drives, but working on the grips at home will help too.
Some dogs aren't genetic calm grip/deep bite, so developing it when they are not in higher state of drive will help.
*make her platz, command the out, then if she doesn't tell her no, instead of out. You could also hold her up by her collar til she outs, but I prefer to platz....command out....reward for the out with another tug session when young. My dog outed fine til he had to really work for the sleeve, then it was higher value. The helper was/is always his focus, not the sleeve target. Some dogs could care less about a sleeve, so having the line before the helper slips is very important. Handler should be on that and never let the dog spit/ go after the helper if the sleeve is not more than a target to bite.
