This Tomahawk 72"x20"x26" collapsible live trap is ideal for large domestic and feral dogs, coyotes, and similar size animals. They are easy to fold flat, and just as easy to set back up. Collapsible traps fold to about 1/10th the space when not deployed. This trap requires some minor one time assembly to attach the front door. No tools are required. Unfortunately, this is necessary to ship it at an affordable rate.This Tomahawk live dog trap is constructed of 1"x1" - 12 gauge galvanized wire mesh.
