The SKN is only the beginning; it really is more about 'What are my responsibilities as a dog owner in Switzerland and in (canton/Gemeinde), what are the basic things I need to know to start my dog on the right road?'. While the course can indeed be tailored to individuals it is based on mandatory content to ensure that all dog owners hear the same message.
My trainer certainly tailors the class - each of the three times I have taken it there has been a different slant, the mandatory content is incorporated in different ways based on the age, character, and training levels of the dogs and on the experience of owners in the class.
But each trainer will structure his/her class his/her own way. This is why it is so important to find a trainer you feel comfortable with, whose methods and philosophy are a good fit with yours, whose teaching style works with your needs. Always ask for a trial lesson before making a commitment to a course - either the SKN or more advanced courses.
I would hope that all dog owners go well beyond the SKN. The 2 Theory and 5 Practical sessions can only scratch the surface. An owner needs to put in much, much more time building trust, building confidence, working on the partnership between owner and dog - either in a formal class setting or on one's own.
I prefer classes (Familienhund, various sports) as in addition to learning, in addition to the fun activities, I feel this is the best opportunity for socialization for my (fruitbat) dogs. I like the support the class members give one another, and I like the opportunity to discuss current thinking in canine behavioral science.
One can train to the same level, work to the same depth on one's own if you have the motivation. No good
training class trains your dog - rather, a good trainer works with you so that you learn how to train your dog.
But make no mistake - the SKN is only the beginning. Training is a life long effort - for both you and your dog.
And remember - if my dog's recall is not reliable and instant... I have work to do.
