I hate that people generalize breeds so much. All dogs can hunt no matter the size. I have a coonhound/bloodhound mix and a beagle mix. I don't 100% trust them but trust my beagle more so than my coon. My coonnie is much more playful and that worries me. My dogs and ducks do well together but I don't leave them out alone if I'm not around.
I have a mixed flock and they all do well together. Sometimes 1 or 2 will go off on their own but they all stick together most of the time. I have 2 runners, welsh harlequin, Cayuga, white layer and crested. No one gets picked on too much or singled out. My Cayuga is low man but someone has to be.
