Dogs have always been considered man's best friend and rightfully so. Whether it is companionship, safety, or even a hunting partner, humanity's kinship with canines has always been strong. Dogs have helped humans out for hundred, even thousands of years. In the beginning, certain dog breeds were bred for a specific job or task. And although times have changed and dogs are no longer needed for the job they were originally bred for, there is still a perfect job for them to accomplish.

A dog's skills have since translated into helping people in need, such as a seeing-eye dog, a police dog, or a search and rescue dog. Certain breeds have a special profile that makes them a perfect candidate for a service dog. Below is a list of the top 10 service dog breeds and what makes them such a wonderful candidate for the job.

1. Labrador Retriever

The Labrador Retriever is without a doubt the most popular breed in the USA. This family friendly pooch is incredibly smart and trainable, qualities that make it a great service dog. Labs are commonly used as assistance dogs for the disabled, sniffer dogs at airports, search and rescue, and even tracking down certain bugs for pest control companies.

2. Greyhound

Though it is likely not the first dog you picture when you think of a service dog, this breed is much more than quiet and affectionate. Greyhounds love to spend time with people and they are a highly sensitive breed, likely to pick up on even the most subtle of clues if something is off. Their hypersensitivity makes them invaluable companions to veterans who suffer from Post-Traumatic Stress Disorder.
