Housebreaking and Using a Leash

We have had our (almost) 4-month old JRT for a week now. We are crate training her and trying to housebreak her. We have previously done this with a shelter-rescued hound and had no problems. This little one is giving me a problem.

First off, she has not yet had an accident in the house. We let her out frequently and I have yet to see her urinate or deficate outside. But, she keeps doing it in her crate. I feed her three times a day and let her out at the necessary times. Her last feeding is around 5:00 p.m. Some mornings she has gone in her crate, some mornings she hasn't. She doesn't necessarily go out in the yard in the morning either. Then I put her back in her crate and within the hour, she goes in her crate.

The other thing I'm TRYING to do is put her on a leash and take her to a specific spot and have her "go" there. Well, she hates the leash. As soon as I put it on, her "brakes" go on and she will not walked. I try to give her little tugs to get her moving and I just end up dragging her. I end up carrying her to the spot in the yard and she just sits there all mad.
