This was perfect for our 80lb Lab with high anxiety!  He has chewed through every type of kennel we bought and even one we built!  Only con i have found is The screws for the front door hinges are a bit to small and the little locking rings it comes with are to tiny if you have arthritic hands.  To solve that we bought a ratchet strap and weave it through the bars over the front door to secure and bought carabiner (d-rings) to replace the tiny lock rings.  Now its perfect!  Longer screws for the front door hinges would make this inescapable.
