I'm only in a beginning obedience class and don't like my trainer. There is only one more class. YAY! Advanced class is being brought up. I won't be taking my puppy to that. If I am asked directly, I will simply say, "We are going to take a break for awhile."
As Blanketback said - it really does depend on your relationship with the trainer. I don't think you should have to go into a lot detail. Tell her you want to try something different. Don't feel bad about doing what is best for you and your dog.
