I purchased two of these  exercise pens and like the flexibility of being able to fold and create two separate areas for each of my Yorkie puppies  when feeding. I then open the exercise pen to allow them to play. The exercise pen has been very helpful with house breaking the puppies (keeps them in one area) and preventing them from chewing walls etc. during the  teething cycle. ( Yes, they have chewing toys/bones but go after wood molding and corners)
