I always have goofy nicknames for my boxers. It goes way back to when we had them as kids. Buckwheat was Bucket
Roxy - Little Rox (I didn't at first realize why it had such a nice ring to it until I thought about Arkansas), Pretty Pretty (in a stupid voice), Doofus, Baby Rox.
Brackus - Ruckus, Root, Rooter-Tooter, Super Toot, "woof" (my nephew is only 13 months old, but everytime he sees Ruckus, he hollars "woof")
Bosco - (my foster) Fat A*@, he's kinda pudgy. Whenever I call Fat A#@, he starts kidney beaning, I don't know why he likes it.
Bain - my new foster, i'm still working on it.
