Thanks all! Gus is now almost 10 months old! It's crazy how time flies....he is a maltese and yorkie mix (however I'm convinced he is almost all yorkie) and he has one ear that sticks up and the other goes down.. it is SO cute. I've read on this board and others that owners are unhappy when their furbaby's ears stick up/down like that..I think it's the cutest thing in the world and makes Gus unique!
