It’s really funny watching these two play.  Boudreaux likes to go for Corbin’s feet and neck.  I particularly like the part at 1:21 where Corbin jumps over him sideways!

If you can’t tell them apart, Corbin is the Corgi with larger white markings.  He’s also the one who’s a lot bigger.  I need to take a picture of them standing side by side so you can see how big Corbin is compared to Boo.  I think Boo is the size of a standard Corgi male.  Corbin really is just a abnormally large Corgasaur.
