I have a cold nosed gyp that would get picked up in trialing but I tolerate her because she produces rabbits. She may be the only one that smells it for first couple of minutes or so and pops off but my other dogs know she has the rabbit and fires them up to search even harder. On a real tough scenting day she is gold! She will be in my kennel until she dies. My only regret is she never has took on breeding.
