My little guy is pretty easy going and mellow. I've read and heard from some Corgi breeders that the boys are more laid back than the girls....the girls tend to be little bossypants. Milo does want to be dominant, but he is not aggressive towards any other animal or person. When I say he wants to be dominant, I mean that when he encounters other dogs, sometimes he tries to climb up on them and stand on top of them!! He once tried to climb on top of a Bouvier des Flanders in an obedience class
Thank goodness the Bouvier was mellow too and didn't seem to mind.
However, Milo gets bossed around by the cat. She rules the roost and he obeys.
