My GSD had nodular dermatofibrosis and we participated in a study with the Fred Hutchinson Cancer Research Institute where they used his blood DNA for their research along with other dogs. He was 5 when we found out he had this.  Everything was documented I have so much information I can give you what we went through and all the tests. He lived to be 10 when cancer took over (kidneys, etc.). Please email me privately and I can give you (or anyone else) information. LuAnn Kennedy ============================================================================ POST is Copyrighted 2009.
