Dude that sucks total ass, can you get a friend to adopt the poor guy? that way you can at least have visiting rights with him, because if hes old he'll get separation anxiety and stop eating. It happened to my friends Black lab he had to be put in a kennel for a month while they went to visit their grandfather (who died not 10 hours after they left his house) and came back to find he had starved to death because he was too screwed up from the change of scenery.
I thought you were one of the older people on these boards?
I hope this all turns out ok
