We have two adult Shelties, 3 1/2 & 4 1/2 yrs old, that we've had for about 2 months. They are "semi-rescues" as they have very limited training and one is very shy. One is so-so on "come" and the other is very poor. We are going cross country by car and are taking them with us. We have soft crates for hotels and staying inside my relatives' homes but the homes do not have fenced yards like we do. We think a tie out would be best when we can be outside with them so they get more roaming room than on a regular leash. What are your recommendations for a no-tangle tie-out setup for two dogs? Neither are pullers on leash or chewers. We will be moving locations fairly frequently so want something simple to setup and take down. Note again, we will not put the dogs out on the tie out unless we are there to supervise.
