I used this pet gate to create a pen for our 2 GSD puppies. They are brother-sister and I didn't want to keep them in separate crates since they are accustom to being together 24/7. Initially, I tucked both ends behind furniture so the pen made a "U" shape (backing up to our sliding glass door). After 1 week of watching us step over the gate, one pup learned how to leap over the pen. No worries, though, I simply reconfigured the pen and moved a few pieces of furniture. With the furniture on the other side of the pen, the dogs do not attempt to leap over and the pen is even sturdier. I have been impressed with how well it takes their attempts to climb over/playing/and bolting through the pet door at top speed. I was also impressed at the price. Great Offer Stock had this listed $100 less than anywhere else. Overall: great product and value!
