Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to acclimate a new dog using indoor leash training [title] Get the right leash. [step] The best leash for indoor leash house-training is a six-foot leash. This will give your new dog space to roam about, but won't allow your dog to get so far away that it can get into mischief.

Ending1: [title] Have a straggle of leashes. [step] Particularly if you're going on an outdoor walk or simply want to expose your dog to a variety of animals, having an straggle of leashes will make the process much smoother and safer. Ending2: A six-foot leash is also ideal because a longer leash indoors could easily get tangled on furniture, family members, or other housemates. [title] Be patient when leash training your new dog. Ending3: Wooden, wooden and rubber leashes are good options. However, please note that you should not use a wire chain with nails in it to house train your dog. Ending4: [substeps] Six-foot leashes are for all the dogs, or one large one containing each dog. One large leashing will help your new dog to get more freedom, and one small leashing will give your new dog more patience.
