I sort of know what needs to be done on the walks. Baby steps at a far distance from dogs and work our way up
closer until she's reactive. At least that seems to be what most online trainers suggest. I can't do the training
very easily as I'm still a little
mobility challenged from a broken femur. So my adult son has been taking her out
once or twice per week on trails, in public places, truck rides, etc. He re-directs her immediately on walks,
but it's not really correcting or eliminating the behavior. But now that she's escalated to reacting from the truck cab-
when she spots a dog quietly walking w/ his owner- it's getting ridiculous. Yesterday, he just cupped his hand over
her eyes as he passed a dog and owner out walking. It worked, but that's not really a good solution.
I'm convinced she's a mix of GSD and some hard headed, obstinate breed- maybe husky. My son's 2 Huskies were
like this when they were young. Very challenging to train. Not at all like my past GSD who "wanted" to obey.
Thanks for your idea of a mentor/trainer.
