Do not buy this product! The wire bars are extremely weak and my 8 week old puppy was able to completely break off the bars and escape! The photo I attached to this review says it all! This product states that it is "heavy duty" but if that were the case, then a little 8 week old puppy would NOT be able to break off steel welded bars from a steel frame! This is a real safety issue for your pets and this product should definitely be avoided!
