We lost our little man to distemper only after hospitalizing him and finding out that the rescue vet misdiagnosed him. We found out that other littermates had died and we were not warned....we had him for 3 weeks before finding out from the foster mom that others died as well. I understand that these things happen but you should have TOLD THE OTHER LITTERMATES! we might have been able to save him or at least help him and keep our other dog away. Thank god he is vaccinated and so far showing no signs.
