I have a Malamute/Heeler/Coyote mix who is 4 years old and loves our chickens. He has only caused harm to one hen 2 years ago when she jumped into the dog pen. She wasn't killed but later died from her injuries... but she was laying injured next to Nanuq (dog) for at least 2 hours before I got home (she even laid an egg while laying there
). So breed doesn't have anything to do with chicken killing dogs.
I recently had one pullet eaten by a neighbor dog though (Heeler mix)... we have constructed a covered run so the ladies can roam during the day without being harmed. But I got some advice from dog trainers, and a dog can be trained to leave the chickens alone.
I was told to have the dog on a short leash and introduce him/her to the chickens. Start by walking them around the chickens and giving the leash a gentle pull when the dog becomes fixated on the chickens, to let the dog know that is an unacceptable response. Gradually the dog
should get the hint, and you can start letting the leash get longer and longer, then hopefully completely loose the leash.
The dogs can be trained... it just takes time and patience. They can all live in harmony. My dog lives with cats, chickens, and bunnies with not a problem at all. Just keep an eye on them and do what you can!
