Does anyone have experience bringing up dogs so that they won't chase/kill chickens? I have two rescued track greyhounds and I haven't even attempted to acclimate them to coexisting with my birds. They've been bred and trained to ruthlessly go after small animals, and I figure trying to overcome that is a losing proposition from the get-go. I just keep them separated, period. But sometime in the next year I'll be getting a couple of Swedish Vallhund pups, and I'd like to civilize them from the start. They're a herding breed, about the size and shape of a Corgi. On the farm where I grew up, there were game hens that were absolutely ferocious when they had chicks, and one encounter with these fierce mamas was usually all it took to teach a pup to give the chickens a wide berth. But I live in a no-rooster zone in the city, so that's not an option for me. Any training tips for new pups?
