We have 5 dogs 4 are Chihuahuas or Chihuahua mixes them I trust with my chickens with me there and alone, I have a beagle mix that I only let out with supervision not that is is mean or anything just part hunting dog and I think he likes to chase the chickens to much, but I have been working with all the dogs to get them to leave the chickens alone so I do think dogs and chickens together is fine but you have to do a lot of work with the dog to make sure that no harm comes to the dog or the chickens. It will take time and repetition to get the dog and chickens use to each other.
