Dog running home? - Page 2

I can't say what her motives are, but I guess she thought they were important enough to take matters into her own hands so to speak.
I love it when they use their brains.... 
Mine is smart enough that she knows she's breaking rules and that there's a price, but she must figure its worth it, or that she will get away with it.
Or she just flat out doesn't give a damned at that moment.   Sorta like teenagers....:)
Either way a price must be paid,  I just wouldn't make it too steep at this point in her life.

There should be a way to set up for this and wait for the moment to correct her, a long line might come in handy.
Another possibility might be just returning to the scene of the crime and working specifically on recall and other basics.

Its a battle of minds and of will.

Again,
Mine gets away with a lot, but she gives more the rest of the time.
I'm not a good one to be talking about retraining an older dog.
She plays me like a fiddle most of the time, I'm so ashamed.....:)

Its a strange task to tackle.  How do you further mold a dog that got the CGC in her sleep and got through a couple legs for CD and RN already.  Also to clarify, she bolted after the sit/stay excersise and had just done a dozen off leash recall exercises in class with other dogs.  Like BeeTree said, she really knew when class was over. The classes aren't covering anything new, they are just maintinance classes that at best sharpen up her form.

But I also don't want to focus on the class as the problem, like I said this issue seems to pop up only in regimented or highly structured settings after several months.  Not to anthropomorphize, but it would seem she is doing at times when she is bored.

LOL.....
Too smart for her own good.
You'll have to decide what your willing to over look, and what must be absolute.

There may be another explanation as weird and silly as it may seem, was she coming into heat around these times of escape when she went back home, just a thought

steve1 in the earlier instances it is possible that she was going into heat.  However I had her fixed around the age of 3 (her exact birthday is not known, just the season and year).  The nose work is more recent and was after spaying.  But in the grand scheme of things it has only been 2 instances since her spaying, but I worry about the behavior because when it does happen I get zero compliance.

This happens so infrequently, I'm wondering if there's a trigger that you're not aware of. This is literally -excues the play on words - a shot in the dark: Is she gun-sure?

I had a GSD rescue that was afraid of gunfire, and one day, while I was having a burger at a picnic bench a fast food place, she kept wanting to get back into the car. Someone came over to pet her, and I remarked on her behavior.

The man said, "Maybe she hears them doing target practise at Base Borden," which was about 15 miles to the north of where we were.

Sure enough, as soon as we got back in the car, she settled down. She could hear the noise, while us humans were unaware of it.

Just a thought. I may be totally off-base, but I thought I'd mention it, just in case.

      I think you answered your own question.She finds the whole regimented  ordeal boring and decides for herself its overwith finally and time to go home.Maybe if you could spice it up a little she might find it more interesting,knowing to some degree when this behaviour is likely to occur,maybe it should end on a different note something she finds interesting enough to stay for the finish so to speak.A big reward and a release word when your ready for her to call it a day might work.The reward needs to be such that she doesn't want to miss out on it.
