At first I thought that this is a math problem, but it's not just that!.
Let's visualize the round building as a clock!. If the dog is at 12:00, he can move clockwise to 6:00!. Conversely, he could also move counteclockwise to 6:00!. Therefore, the answer is that he can patrol the entire outside of the building!.
So, mathematically, the dog can patrol the entire circumference which is 3!.14 x 20 = 62!.8 feet!.Www@Enter-QA@Com

I say 62!.8 feet!.
The building is 20 feet in diameter, meaning that circumference is 62!.8!. The circumference is used because the dog has to go AROUND the building, not through it!. Since the dog can move in both directions, he can span the whole building!.Www@Enter-QA@Com

actually about 63 feet!.
to get the circumference you multiply the diameter by pi!.
since the dog can wind halfway around both sides, it can wind around the circumference, which is about 63 feet!.Www@Enter-QA@Com
