A: The clamp-on type is unlikely to work because you won't have screen to clamp onto on two sides. You'll need to replace the damaged screen, and then install the pet door. If you're planning to get a dog door that fastens to the screen frame itself then, as long as the pet door frame is larger than the torn out portion you'll very likely to be able to do the install with the screen "as is". This, of course, implies that you have the skill to re-spline the screen to the pet door--a job that isn't particularly easy. You might need to make a trip to the screen shop just to make sure you get a good result. Larger in size than our cat flaps, the pet door is designed for large cats and small dogs
