Baby has a name - officially he will be known as Scooter.

Brother says he's such a good boy. He's quiet at night and hasn't had any "accidents" - so far!

As far as the others accepting him:

Buffy has snapped at him a couple of times
Sandy loves him
Cocoa hisses and growls at him
Smokey ignores him

Being that Buffy and Cocoa have ruled the roost for so long, it will probably take some time for them to get used to him, but my brother trained dogs in the past, so he knows how to handle it. They'll come around eventually.........
