also if she is allegery to the nylon most harnesses are made of it.It make irritate her whole body instead of just neck. I would for sure try leather before you bought anything else nylon rather it be collar or harness.
here is collar & leash that I kinda lean to when I buy for myself or a gift to a friend.They both have deer skin (the deer skin side is what will be touching her neck) so maybe that will help her.The leash itself only has deer skin where you hold on it yourself but both for $ and no troubles (with my expereince) is excellent.

these are all great collar ideas. Im going to look into them when Maverick is a little bigger. I hate buying collars for him now that are expensive since he walks on a harness and out grows them so fast, Still he will need a tag collar eventually. I had to ask, do you ever wash her cloth collars? Ive heard that they can get dirty and harbor bacteria but also if you wash them sometimes the detergent could make your pup break out. just a thought, hope it all works out!
