Dozer will be starting puppy obedience classes soon. He will not stop at that. I plan to do quite a few classes with him. We will start with Puppy (under 5 months old), then head into Adolescent (5 months+), move to the Advanced Obedience from there and then Applied Obedience. I also plan to do some other stuff with him as well (Canine Social Etiquette, etc.). Where I'm going has a Running and Massage Clinic, and that looks interesting to me as well. The woman where I'm going is a trainer/behaviourist. She does private sessions as well as group sessions.
Both boyz started Kinderpuppy at 10 weeks, and have been in one sort of class or another pretty much since then, though we do take a hiatus in the dead of winter (our classes are over an hour away from our house, twice a week) and in the middle of summer.
Henry is currently formally training in Open obedience and Ollie will be starting Attention 1 since we've completed Competitive Puppy 1 and 2.
I also do a lot of rally exercises with the boyz on our own, as well as doing their obedience training.
Still going! Puppy class, CGC, Agility - whatever else I can convince the pup to do. But I also do a lot of training with him on the side - not necessarily tied to any class (Usually stuff we don't learn in class, but can be fun/useful)
I didn't vote because I didn't see a choice that seemed to fit us.
We attended a once a week, 8 week class on puppy training when Puff was about 6 months old, primarily to check me just in case I was doing something in training Puff that I was unaware of. I'd already trained one Lab (Bess) on my own and know the basics in learning theory and application.
I started training Puff (NiLiF) before that class and after it and we go through refreshers (non-class) every so often.
There wasn't really an appropriate choice so I selected Puppy class.
We did a couple of obedience classes plus a few agility classes, but no specifically CGC-related stuff. We haven't done any formal training classes for a few years.
I took Emilu to the first "puppy class " I could find, but she was almost 8 months old - she is now 6 years old and has been in almost continuous classes as we started showing in obedience competively. I had trained Skippy myself the basics, and had taught her the basics, but I find classes invaluable for all of us, and the dogs LOVE to go to class.
