Make sure that they have classes for small breed dogs. I enrolled Pixie in puppy kindergarten class and I went for the first meeting and found out that she was the only small breed dog and that they have 15 minutes of free play with NO interaction from the owner and I declined the class and lost part of my money. I just didn't think it would be fair for Pixie to have to interact in free play with a two great danes a siberian huskie and a golden retriever. I was afraid for her safety.
So I am training Pixie myself and I will socialize her by maybe a small breed social.
