It would be worth checking with each place to see how firm they are on the requirement to take their classes. Some of the facilities I took classes at with Halo listed a prior class taken there as a prerequisite, OR a comparable class taken elsewhere. Four of her first 5 obedience classes (Sirius Puppy 1 & 2, a CGC class, Family Dog 2 and Basic Manners 2), were taken in different places - a deliberate choice I made.
The first two were the same program and instructor, just different locations, and the CGC and Manners class were at the same place, but a year or more apart. She also took her beginning flyball class there. Family Dog 2 was at a humane society, and since I'd taken her earlier classes elsewhere they required us to "test in" by demonstrating that she already had the skills she would have gotten if we'd taken their beginner class. I simply made an appointment, brought Halo in, and showed that she knew sit, down, stay, a recall, and some leash skills. We got the okay for either FD2 or 3, but their previous level 3 class had been cancelled because there weren't enough signups, and it would have been a less convenient day and time, so I took the level 2 class. Our flyball club also practices on a field at that humane society.
If there had been a place where I could have taken a variety of classes from basic beginning all the way up to a sport I might have started there and stayed there, but that wasn't always the case. Also, I liked the idea of generalizing Halo's training by having her in novel environments. When she was a puppy I worked with her in a different room in the house each day, and once she was a bit older and I was doing more of her training outdoors, I'd take her to different places to work. We went to both of the pet supply stores in town, three different strip malls, we trained on busy street corners, next to gas stations, by the baseball field while kids were practicing, and a basketball court, outside the bowling alley and the supermarket with automatic doors and people going by with carts.
Yes, this is something I am looking at too. On the humane society page, for advanced classes it lists basic obedience OR permission from the instructor. So I am thinking maybe if we take Bruce to the other club that has the agility and other basic classes, and take him to obedience classes there we can get permission from the instructor by showing his certificate of training from the other place, showing his skills, and also since we have already taken a class there, we are going to be using their methods to start Bruce before he is old enough to go to a class. I just don't want to pay for two different basic obedience classes, if there are no ways around it I would. I did REALLY like the trainer at the humane society, she was very knowledgeable, has a GSD herself, and really cared about the animals. They just don't offer any sport-related classes. And one thing the trainer STRESSED at the humane society was how in order to really get your dog VERY obedient, you have to practice a LOT in a LOT of different places, practice at the park, before the gate, in the gate, down at the bottom, practice near the car, practice in the driveway, practice in the porch, practice in the kitchen, bathroom, bedroom, living room, dining room. She said dogs remember things by pictures, so if they remember a certain phrase or gesture in the living room, next time you are in the living room they will remember, but not necessarily when you are at the park. She said it takes 2 years of constant training, and a 100 different places to get your dog good. So if we can take him to obedience classes at different venues, I would prefer it, I just didn't know if anybody had reasons for why not to take him to different venues, such as different styles could confuse your dog or something. Which I agree, it could, but if we go to a trainer with a style we don't like, it is OUR dog, and our word is the final say on how we train him. That is my opinion.
