Everyone has different opinions so I'm not saying yours is 'wrong', but ....
Lizzybeth is going to be teaching clicker training .. plenty of people have never even heard of clicker training. I am familiar with clicker training and it's principles ... but have never actually used clicker training so I would really appreciate it if a trainer using that particular method had a "no-dogs" policy for the first class!
Ihartgonzo also mentioned the place she brings her dogs (4Paws University) does a first "no dogs" class ... and 4Paws is one of the best places to bring dogs for training.
I think that one of the problems with how clicker training is taught is that it's presented in such a way that really intimidates people. While it is a science, it's certainly not rocket science and can be explained and demonstrated.. and used in a very short period of time.
I used to teach all of my classes without the dogs present. I added clicker training some 10 years ago and have been using them in all of my puppy classes and many of my other formats without difficulty with respect to client understanding or compliance ever since...with the exception of the first few months when I felt it necessary to explain the heck out of what a reward marker was.
Now, with a brief discussion on 'why' clicker training works so well, what it means to the dog (that a reward's coming), and how it's best used by the owners (like a camera, 'clicking' a picture of what you wanted to see), I've seen a drastic reduction in the confusion over this powerful, temporary, and really simple training tool.
I do hand out my own booklet to every client with every clicker question known to man/woman for reference and of course we continue to fine tune, dispell myths, and teach principles as we go.
I found that if presented as clearly and simply as it really is, it's actually quite easy to do on the first night with dogs present.
I also used to do the owner exercises and other techniques that I learned from Chicken Camp in order to gently 'desensitize' clients to the clickers but found that this over-explanation made things much worse. People were over thinking everything and many just dropped the clicker because it seemed to complicated.
I started 16 puppies last night, will start another 32+ tomorrow and each one will learn and use the clicker within the first 1/2 of my 1 hour class..with success.
I've also dropped the old "charge the clicker" routine as well. This is another exercise that I find wastes time and complicates the process. If done right, we all know that a "clicker virgin" puppy can and does understand the meaning of the click by simply using it for a new, easy behavior such as "Watch Me".
Again, this is just my opinion but having done this for as many years as I have and having done it both ways, I'd never waste an entire class and the opportunity to meet and 'read' new dogs in order to have the owners undivided attention. It is a dog class after all..
Oh, and I have to add that I am a BIG believer that training is about the owner and the dog, not the trainer and the dog, and I make that clear in every class. The dogs presence in the first class is entirely for the benefit of the dog/handler team and the safety of the group.
With all of my classes, like I've stated in a previous post, I am extremely detailed with my registration to avoid or eliminate first night safety issues. Rules are very clearly given both over the phone and with follow-up email to all who attend.
I can't tell you the number of people who choose my class over other, equally qualified trainers simply because their dog can attend and begin learning from the very first night.
Just another way to look at it....
