Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to train dogs to leave chickens alone [title] Spend time with the dog outside. [step] As the two of you are outdoors together, aim to get close to the chickens. Introduce the dog to the chickens only when the dog is on a leash.

Ending1: It's a good idea to sit near or among the chickens, talking to them gently and to the dog gently too, keeping everything as calm as possible. If the dog can see that you care about the chickens and treat them as important, it may realize that the chickens are off bounds. Ending2: The dog should not chase after the chickens or fear them in any way. [substeps] Provide enough space for the dog to position its body more towards them than away from it. Ending3: You don't need to worry about the dog's safety while you are inside the coop. However, your dog needs to know that it's safe when the chickens are around. Ending4: If you stay indoors with your flock, the chickens will be more interested in returning without you, and therefore expose you to chicken. But even then, you should try not to be too aggressive, as eventually the dog will get used to you and won't prefer to spend time with you in enclosed areas.
