I got a handsome Boston Terrier, Trogg Delight, and chubby little clown pit/border-collie cross named "Fat Aspen". Both are great with chickens and little kids, but not so much other dogs cause they play so rough.
I have a Papillon named LeRoy (aka Peapod) and a Heeler x Border Collie named Twister (aka Dingo)...
Twister's first birthday "party":
They do the run by really fast and sniff thing with my birds just to freak them out. Twister would probably nail one given half a chance, but then she wouldn't know what to do with it. BUT my dogs are on one side of the house and the chickens live on the other side of the house, because I really don't want to know...
