With a mesh height of 34 inches, Retract-A-Gate is one of the tallest retractable dog gates available. When locked, the mesh is held taut, so it is difficult to push down. Retract-A-Gate’s tightly woven mesh fabric would be difficult for a dog to climb over. If your dog loves to jump and can jump over a three foot fence or safety gate, you will need a taller dog gate.
