Love this kennel.  Bought it to contain a 14-month old Labrador Retriever.  Connected 2 kennels together, will connect more as she gets older.  Installed a dog door on exterior wall of house that allows her to go in & out to kennel area on her own - works great.

Kennel gate has low headspace so have bonked my head a few times on the bar above the gate but other than that they are great and pretty sturdy (we secured them to the side of the house).

Gate latch is flimsy so we use Velcro to better secure the gates.
