The "No. 1" dog depends on the region and criteria, but the Cavoodle (Cavapoo) is Australia's top dog, favored for being small, intelligent, and low-shedding; while in the U.S., the French Bulldog is currently the most popular according to the American Kennel Club (AKC) and has held that title for a few years. Traditionally, the Labrador Retriever held the top spot in America for decades.

The #1 smartest dog breed, consistently ranked by experts like Dr. Stanley Coren, is the Border Collie, known for its exceptional ability to learn commands quickly (sometimes in under five repetitions) and obey them consistently, excelling in problem-solving and demanding mental stimulation. Other top contenders for intelligence often include the Poodle, German Shepherd, Golden Retriever, and Shetland Sheepdog, recognized for their trainability and eagerness to please.
While there's no single "number one," the Golden Retriever and Labrador Retriever consistently rank as top friendly dogs due to their gentle, outgoing, and loyal temperaments, making them excellent family pets good with kids and other animals, though they need plenty of exercise. Other top contenders for friendliness include Cocker Spaniels, Beagles, Cavalier King Charles Spaniels, and Pugs, known for their playful, affectionate, and people-loving natures.
The calmest dog breeds often include large, gentle giants like the Saint Bernard, Newfoundland, and Great Dane, along with smaller, easygoing companions such as the Cavalier King Charles Spaniel, Basset Hound, Pug, and English Bulldog, all known for their relaxed, affectionate, and laid-back temperaments, though individual dogs vary. Sighthounds like the Greyhound are also surprisingly calm indoors, needing short bursts of energy but otherwise content to lounge.
