Recently bought two Shih Tzu puppies. The corral is perfect! We put the pups in it when we leave the house and at night.They are now at the point where they will go to the corral to use the wee wee pads. Really keeps them out of trouble and we don't have to worry about them getting into things when we are sleeping or not at home. 
I would only recommend the corral for smaller breed dogs. A German Shepard sized puppy will soon out grow the corral. Best for puppies that will not be heavier than 20 pounds when grown.
Easy to assemble,set up and clean. Really worth the price if you have small dogs.
