Mom0810, you're very big on putting down others' experiences, but fail to share your own aside from being a breeder. What titles do your dogs obtain other than conforming to a standard (again, no training required there). Have you worked as a trainer? (I'm honestly curious which reputable trainers will still advise rolling a dog - I thought that had gone the way of keeping dogs on tie-outs and feeding Alpo) Even the monks of New Skete, who started the whole "roll your puppy" craze - no longer advise doing it!
Actually, I'm not putting down anyone's experiences... I feel like that is what is done to me all the time, actually! I have answered this question here before, but here goes... Yes, I am actually a REAL life trainer! I teach obedience classes, puppy through advanced. I teach agility. I have done schutzhund, tracking and all kinds of other training. I HAVE TITLED DOGS in obedience, agility, herding...etc. I have been in dogs for over 30 years. I have worked as a vet tech, a groomer (since i was a child), apprenticed with several VERY top handlers, and yes, I am a breeder. I have bred MANY champions, owned and co-owned several top dogs in a couple of breeds. Dogs are a family affair and I come from a family of dog people, too. I am a member of SEVERAL all breed and breed specific kennel clubs. I've done it all, and I've done it my whole life.
I have been really careful NOT to give too much away about my identity, because I have been really open about discussing PPD on MDC, and I suffered with it twice. IF you are a dog person, and IF you have shown anything in obedience, conformation, etc... then you know how vicious dog people can be, and to let anyone know any kind of weakness on my part would be not a good thing. Of course *I* don't perceive PPD as a weakness, but there are some very mean and spiteful people out there. Once you win ANYTHING... they will be eager to get something "on" you. So yes, I have been really nonspecific. It's all very intentional.
I have been doing the alpha roll technique for so many years, gee whiz, I can't even remember the first time I learned it. But it was decades ago. And yes, there are SOME who disagree with it. So what? I don't like clicker training. There are people in training who think that "prong" or "choke" collars are abusive. I disagree. As I have tried to explain to others here, in dogs there are so many "right" answers that nothing is really wrong after a while. Techniques come and go, and fads come and go. My technique works for me, and decades of VERY happy clients... so I still use it. I have tried other ways, and they don't work as well for ME and for MY DOGS. I still do this, others may not. That's fine. The longer you do dogs, the more you say, "oh well," when someone disagrees with you. It's like each to his own, you know? It's usually the mark of a true novice to wonder why everyone does not do things all the same...or that certain training methods are long gone... or that something is just "wrong". There is much gray area.
The poor OP... sorry Sara for the hijacking of your thread. But I felt this had to be answered... again... hopefully, this takes care of it.
