Our Dog Run Kits come with all the components you will need to successfully install a superior dog run. Our LBU10 or LBU15 animal tie out is needed to attach your dog to the run. These kits can be installed between two posts or trees. Our runs incorporate stops to prevent the tangling of your dog around a post or tree keeping them happy for long hours. We recommend this heavy duty run for dogs or animals weighing 75 lbs. or more if you have a very active & strong dog. This run is 50 ft. in length.
