i know how you must feel, the difference is that when we moved (to another state, no family at all, no friends and all) I did take my dog (I had one at the time ) and it was because my dad got promoted 2 and a half years later we got back and we were so thrilled about it............

hoping there´s something better than just "because he likes it there" i believe if its for that reason it should be a family desision (sp?) unless it was for job issues, then it would understandable, and besides with all your grandpa being sick he might consider what your mom and you have to say, it really is not a good timing "just because he likes it"

sorry if i sounded harsh, that was not my purpose. just to let you know that i get you and i´m here for you.............hugs....
