I believe this pen would work well for small to medium dogs…i.e. Poodles, Malteses, Beagles.
Unfortunately I was trying to use it for a 2 yr old Blue Healer and it took longer to put the pen together then it took him to escape it.  The material used to make the pen is light weight, but very flimsy ￼in its construction with the pin rods bending easily causing the sections to fall apart.  Therefore, it’s not likely I would not buy this product again.
