@Quercus:
IMO, her shelf is nice…but she could use a little extra second thigh (I think that is term); it looks like the steep angulation in her lower leg doesn't compliment the nice angle of her pelvis.
I see what you mean about her stop...but from the side it looks nice. Luna's head was like that too...obvious stop from the side, but from the front, or oblique angle, it looked strangely smooth...I like the name banana head Her head looks a little domed, rather than flat on top...maybe that is giving the impression of no stop?
This was regarding Arlene's pics.
As far as Jazz…I think she is a decent bitch, and you should give it a shot to show her. As you know, it is hard to judge from pics alone...movement is so important. Depending on where you are, it might be difficult to finish her.
She also is very young, yes? So she will most likely grow into her ears. She has some faults, but nothing glaringly terrible, IMO. Also, IMO..she has more white than I would like to see on a show dog, and as Arlene mentioned, where her white is, might hurt her more than how much there is, because it exaggerates her short upper arm. But I would definitely give it a shot, if you are interested in showing. There are scads of nice and supportive people in your area, so give it a try
