See that's too coincidental to me for a rare condition like that???....odd.Thanks for that. i intend to, when my second dog, related to the first one, contracted the same cancer I mentioned it to my vet but he dismissed it as unlucky. I was too distraught at the time to take it further. However, over the past week it has all come back to me and I will be discussing it with him at the beginning of the week and if he doesn't help then I will be talking to others about it. Around the same time 2012, my neighbour's young horse contracted the same cancer, we talked about it at the time too but I will bring it up again with her when I next see her. Too many unanswered questions and I have 4 other dogs and 3 cats to think about. Thanks again. Jx
