I would always WANT my dogs back and I think that due to my having them in my name (registered in multiple ways) that I should rightfully get them back. I would pursue legal action.
But really. The natural disaster thing. Just. Look at this:
I'm sorry, but this man LOVES his dogs. I know because I am lucky enough to own 3 of them. He would have stayed there through the fire if it weren't for the Sheriff coming and forcing them out and his wife being ill. The whole ordeal was terrible for all of us in the breed club, and I've become very close with Tom and his wife over the past 3 years. I was hysterical for days until we knew all dogs (except for two, unfortunately) were safe and had been fed and watered by firefighters. I don't get snippy at a lot of things, but some people really need to think about what they are saying before they hit "Submit Reply."
ETA - If it were someone else's dog, it would break my heart, but I would give them back. Though I would totally try to find the owners if there was already a name associated with a microchip ASAP.
