When the Boxer breed was first introduced to the world, everyone thought they were one of the smartest dogs of all time. However, in 1994, a book was published that became the ultimate guide to canine intelligence.
This book claims that boxers are only of average intelligence.
In the past, boxer dogs were popular performers in the circus ring. They made ideal circus performers because they are so highly trainable, energetic, and strong. They also have very fun, mischievous natures and are sometimes called the clown of the dog world.
