Why did I waste my time with the inexpensive kennels!??  this is great.  My Medium sized Retriever and my full Golden Retriever fit in this together comfortably.  These two excape artists have not been able to escape.  They are total freaks when it comes to thunder and fireworks.  Now they have a nice quiet place to chill out together.  EASY to put together.  Very heavy, but sturdy.
