One man and his 13 dogs

A dog may be man's best friend, but many dog lovers end up with numerous canine companions over the course of a lifetime.

Bill Henderson has had a total of 13.

The author of All My Dogs: A Life has dedicated his memoir to a shaggy mutt called Lulu who he describes as his "life dog".

The book covers his own strict upbringing, rocky times in his marriage (he credits a dog with saving it), and the birth of his daughter. Each of the chapters is named after one of his dogs.

Describing it as a "mutt memoir", Henderson says the book is half about humans and half about dogs. His conclusion is that dogs are more than just man's best friend, they are an essential member of the whole family.
