As anybody can run a dog training class – Do you know if your dog trainer is qualified?
Are they registered with the Association of Pet Dog Trainers or similar?
The APDT, UK are proud of the fact that they assess all members according to a strict criteria which ensures they have appropriate skills to teach dog training. They are required to keep their education up to date, and adhere to a Code of Practice. If any member is found to be in contravention of this Code then their membership is withdrawn.

I use the facilities of a so called "centre of excellence" to train my dogs myself. However I think that it is vital to socialise my dogs, consequently I have also taken them to classes throughout their lives.
The centre that I use has a limited amount of experienced trainers, they need other people to take up the slack. To enable them to do this, their kennel and office staff go to one day and on-line courses to gain qualifications and then they take classes.
When inexperienced owners have a new puppy, it is difficult to establish which classes that they should attend. My advice is that they should sit in on several classes before they decide.
Although the Asker says that trainers should be registered with the Association of Pet Dog Trainers or similar, I have always opted for trainers that have a wealth of experience and with a proven track record. Nevertheless if they are registered this is a bonus.
I have no qualifications, however I take pupils FOC. At the outset, the pupils are told that I have no qualifications. Unfortunately I failed with one of them, she could not decide which end of the dog to lure or treat. Afterwards she hired a hall and now charges to train dogs.
Beware anyone can run a training class.
EDIT. I think that this Asker was warning new and inexperienced dog owners. Any idiot can run a training class, however if they go to a qualified trainer who has a vast experience of training, it helps.
