What is the top speed of a pit bull?

The premise of your question contains an incorrect assumption. Pit bulls, like other dog breeds, do not have a specific top speed. The speed of a dog depends on several factors, including its size, breed, age, health, and training. Pit bulls are typically medium-sized dogs, and their speed can vary from roughly 15 to 25 miles per hour. However, some individual dogs may be able to reach higher speeds in short bursts.
