I spoke w/ I think her assistant and she said that they do not require prong/choke collars. She said to just come in what he is most comefortable with. If she is a reputable breeder (she also does the training classes at my local PetCo) I don't think that she would do anything unreasonable w/them when their owners aren't present.
Thanks for the advice.
I AM SOOOOOOOOOOO EXCITED!!!!
