Cockapoo tears

A very nice lady came into work yesterday, in almost tears, looking at shock collars. As I'm prone to do, I wandered up, asked her if I could help.....what kind of dog she had, what her issues were, and about thirty minutes later, she came up for air.
Seems she has a two year old cockapoo. One of the 'new designer' breeds. Very cute little dogs. I've had several come through class and adored them all. This one was driving her insane. "He's already gone through several shock collars" a sign that says to me, she was neither using them right nor buying a new one from me (yeah, I have the power to say No, and Will if I think they will be misused).
The dog's - her - issues were basically "he doesn't get enough exercise and so drives us nuts with his energy, he barks all the time, especially when he's locked in the garage because we can't stand him anymore, and he won't ever ever leave us alone in the house, he's always herding or jumping or....and oh, was barking ALL the time mentioned?? On and on and on and on. And when he does get to run, he won't come back."
Not much of a good life for the dog, or much fun doggie time for lady, her husband - who loves the dog, won't allow her to give it away, and yet won't take over any amount of care for it, and the two kids who hear mommy yell at the dog and are almost afraid of him at this point.
I tried my hardest to steer her toward training - which Can cost less than a shock collar, just to get the basics! And will last a lifetime.
This is one of those occasions where in home training would be a very good idea.
Will keep you posted if she and her husband call me. Fingers crossed. I think this is one of those dogs and his family that could be turned around, happily, fairly quickly if a good trainer (me) got involved.
