I guess I'll put it this way.
Currently, every year I do 3 sessions of drop in obedience classes (these are competition level classes). For 2 dogs, it costs $220 per 6 weeks. These are classes with OTCH trainers teaching them. The one dog is in a Utility class and the other is in a novice/open class, so think lots of equipment involved.
So $220 x 3 = $660
For the next 1-3 months or so, I am also taking some drop in classes for handling (conformation) - taught by a professional handler who is actually actively handling goldens so much to learn from her! Not every week, but assume 4 classes this month, maybe a couple next month, and a couple the following month. That's $15 per class.
8 x 15 = $120
I'm also taking privates every other week with an OTCH trainer in my area. That's problem solving and focused training with my older boy and that's foundation building with my puppy.
That's $10 every other week for both dogs.
So assume 2 classes per month x 12. That = $480.
My yearly total of classes =
660 + 120 + 480 = $1260
I'm going to add a little extra tidbit. The $660 is primarily a donation to the club. Club membership means paying 1/2 price for classes and perks like being able to use the training facility any time there isn't classes. Most clubs operate like this, so it's possible for you to really get serious about dog training and pay less as well! But anyway, I could be paying $330 instead.
But as it is, all of those classes that I'm taking with 2 dogs - group classes, handling classes, and privates (I get 2 hours to really work on problems one on one) = etc, etc for a whole year, all costs 1/2 the amount of what you could expect to pay for 1/2 a year at that Argos place. o_O
When you consider all that, I would be evaluating whether the training classes at that Argos place or Petco or whatever are worth that excess cost beyond what you could be paying elsewhere.
Dog training classes at your area clubs might cost more than I pay here in MI, but not that much! Or I doubt it?
