I wish we had purchased this years ago!! We have a very anxious Aussie who was bending up her past kennels that were supposed to be heavy duty kennels. This was is VERY heavy duty and once this kennel defeated her when she found she couldn’t get any give or bend it she has stopped trying. It has actually calmed her down and she likes it. We do too!! You won’t be disappointed. We put the tray inside the kennel so she wasn’t laying on the bars.
