Considering that Clifford is 30 feet tall, while the average dog is 22 inches tall, and the average dogs dick size is 8 inches, that means that Clifford’s dick is about 16x larger than the average dog’s, assuming that a dog’s dick size is proportional to its height. This makes Cliffords dick about 160 inches long or about 13 feet long. To put that into perspective, that is about 2 full sized beds long, or half a London bus, or twice as long as two refrigerators on their sides
