According to Svartberg's data (PDF), a pinscher, a Bernese mountain dog, or an English springer spaniel might be the most disloyal since each ranks very low on playfulness, with moderate sociability.
Basenji. Among the most independent dogs around, Basenjis don't need a whole lot of affection from their people, making them a good fit for someone who wants a dog friend but values their personal space. The handsome Basenji is known as the “barkless dog,” but they do make a yodeling.
Chow-Chows tend to be notoriously stubborn. Not only are they among the dog breeds that don't like to cuddle, but they also are among the breeds that sometimes don't even like company.
So, when someone acts negatively or in an unusual way, dogs sense that the person is likely bad. This leads them to want to protect their humans at all costs. We often have bad feelings about other people, but when it comes to telling whether someone is good or bad, your dog ultimately knows best.
For example, grey hounds, Shiba Inus, Cairn terriers, and Basenjis often bond strongly with one person, while Labrador retrievers, golden retrievers, poodles, and beagles like to spread the love more equally.
Poodle. A poodle may have an impressive head of hair, but believe it or not, this breed does not shed or smell. It comes in a variety of colors and sizes so you can get one that's short, tall, black, white, gray or even apricot. They are intelligent and easily trained making them great show dogs.
The smaller breeds of dogs tend to live the longest. Yorkshire terriers, Chihuahuas, Dachshunds, Toy Poodles and Lhasa Apsos are the breeds who typically live the longest with these averaging a lifespan of up to 20 years. This is much higher than the average lifespan of a dog which is between 10 and 13 years.
