Seriously?

This is not a sheltie and I don't know where they found it but they brought it home! Allana keeps telling me I should feel sorry for it. Apparently it has a microchip that was never registered and the rabies tag from 2011 can't be traced back to any owners through the vet clinic. What are we going to do with it? It is not a sheltie so it really does not belong here. Why did they bring it home? My parents have lost their minds!
