For a person new to training, I think a trainer or classes are invaluable, though I agree that a bad trainer is worse than not trainer. Group classes are great because they are cheaper than individual training, they hold their own distractions with a variety of people and dogs, and everyone is dealing with their own problems which you can gain a lot from. And working with a group, a lot of times, gives me the motivation to have a good week every week -- always someone's dog is giving them more problems than mine, so it is kind of a boost too.
I hope one bad trainer does not taint the whole of trainers for you. Because I think that you may miss out by not having a trainer at all. A trainer can see things about how our dogs react to our body language that we may not recognize ourselves, and they may have suggestions about things we may never think of on our own.
I am sorry you had such a crumby go-round with this yayhoo. Good luck finding someone else.
