Ruff Tough Kennels

A great solution. They are much better than Airline crates. More internal room and they have optional hardware to lock them together. The gates open either direction and the have an option to have the gates on both ends. Shown is the Intermediate size (not Medium) and is plenty big for dogs up to 50#. They say larger dogs can use this size. They have a nice video on the website. Roughtuff Kennels.
