Sometimes, new members of the family are last minute, and unexpected but pleasant surprises. (We've had surprise new members of the family before, such as Lulu.)
This is Davy, the Boston Terrier. We found out he was going to come and live with us on Christmas Eve. The boys didn't find out until Christmas morning. They found out that he was coming because I put a picture of a Boston Terrier with the note "Merry Christmas from Davy. I'm coming to your house next week." It took them a little while to realize it meant we were getting another dog.
He's a bit hyperactive (he's been kenneled for a few weeks because his owner has become very sick), but that should settle down soon.
He does have a constant expression of OMG! on his face, but that is endearing.
This one isn't thrilled that he's here, but she's keeping an eye on him. Always. Her displeasure is lessening, and I think they will be just fine in a few more days.
