A trolley system allows a dog to freely and comfortably move between two stationary objects with access to food, water and shelter. When used properly, it provides maximum space for a dog to safely roam, ensures your dog access to food water, shelter and exercise, and prevents your dog from getting loose and potentially harmed.

According to California law, you may attach a dog to a running line, pulley or trolley system, like the one pictured. It is not legal to tether, fasten, chain or tie a dog to a stationary object, such as a dog house, tree or fence. Properly installed, your dog should not be able to become tangled on the line or neighboring structures.

Please follow the instructions provided with your system. If you need assistance setting up your trolley system, please contact our Humane Law Enforcement team at 619-299-7012, option 1.
