Thanks for link, LD.
Just watched several of the Cheri Lucas videos, she has many!
Didn't see any of high energy and/or prey drive Dobermans...
Lots of good information, but with some observations, as others have mentioned:
Her videos with dogs in them are much more effective than just straight talk ones.
Why is it necessary, or desirable to walk 7-10 dogs at once?
I believe she should demonstrate pack behavior with 2-3 dogs, which most people might experience. When I walk (2) Dobes at once, en route to a nearby unimproved park area, people clear away when they encounter the Doberman pack...
Head harnesses a no no for Dobermans...
Call me a sexist, but Cheri's tight, low cut revealing yoga outfits in many of the videos are a distraction from the good canine information being conveyed. Yeah, she's fit, but she shouldn't flaunt it. And, having no pockets or pouches for extra stuff needed on dog training or walks is impractical, IMO. But I suppose in this world of YouTube and advertising, anything to pull viewers in, goes.
