The Labrador Retriever is ranked first among all dog breeds. This is owing to their exceptional, accommodating, and adaptable nature.
"Golden Retrievers are very people-oriented, affable, gregarious, and trustworthy," adds DiNardo, who also notes that they are devoted workers.
These dogs are the fourth most popular breed, and they are also used as K-9s by the military and police.
It is hardly surprising that the Poodle is so popular. Poodles are available in three sizes — regular, miniature, and toy — and may reach a height of 15 inches.
"A well-bred and well reared Rottweiler will be calm and self-assured, brave, and a family protector."
Although the Boxer was recognised by the AKC in 1904, it did not become popular in the United States until after World War II, when returning troops brought the dogs from Europe.
