And we still have no idea what he is- sometimes he looks like a long dog (Corgi, Daschund, etc) cross, and sometimes he doesn't.
But he pretty obviously adores his older brother. He has a habit of sitting on Chowder's head or feet. For the first 2 or 3 times this happens, Chow will move. After that, he just gives up and accepts the awkward cuddles.
And they do spend a lot of time cuddled. I think Chowder is pretty content with his new little brother. They spend a lot of time wearing each other out with viciousness. Then they curl up and make me smile!
Pepsi still does not know if she accepts this interloper, but she hasn't tried to eat his face yet, so I take that as a good thing.
