Bringing a dog to work may have been unheard of in the past, but many companies are now allowing their employees to have man's best friend accompany them to the office. Of course, there's a difference between a well-behaved, friendly canine residing at a colleague's desk and having the pet distract and disrupt the working environment.

Luckily, PetBreeds, a pets research site in the Graphiq network, ranked the best dogs to bring to work. Using data from Animal Planet and the American Kennel Club, PetBreeds created a "Work Score" scaled from 1-100 to measure how well variations of Fido would fit in a workplace environment. The score is comprised of eight equal criteria: obedience level, barking, energy level, trainability, protection ability, friendliness toward strangers, shedding and affection level.

It should be noted that no dog breed scored over 80 out of 100 on the Work Score, suggesting that few breeds are completely suited for office life. Also, the age of the dog makes a difference. It's probably not a good idea to bring your untrained puppy into work, even if its breed does possess a high Work Score.

Note: Ties were broken by dog breed popularity, ranked from a list of 1 to 184 breeds. Work Scores are calculated to five decimal places. For the purpose of this ranking, we rounded to the nearest hundredth.
