Bursting with perpetual happiness, Golden Retrievers have never met a stranger they didn’t immediately consider a friend. Their tails work overtime as natural welcome wagons, making them absolutely terrible guard dogs but wonderful social ambassadors.

President Gerald Ford’s beloved Liberty brought this breed’s friendly nature to the White House. These golden-coated love machines will likely show burglars where the valuables are hidden in exchange for a few belly rubs!

11. Labrador Retriever

America’s most popular breed earned that title through unmatched friendliness that extends to absolutely everyone they meet. Labs approach life with boundless enthusiasm and a firmly held belief that all humans exist specifically to pet them.

Originally bred as fishing companions in Newfoundland (not Labrador!), their working heritage gave them a people-pleasing attitude. Your Lab might bark when someone knocks, but it’s more from excitement about making a new friend than any protective instinct.

Following their noses through life, Beagles greet everyone as potential treat-givers and ear-scratchers. Their friendly baying might alert you to visitors, but only because they’re announcing new playmates have arrived!

Snoopy represents this breed’s playful spirit perfectly. While Beagles make excellent detection dogs at airports thanks to their incredible scent abilities, they’re far too sociable to distinguish between welcome guests and unwanted intruders.

Carrying themselves with the confidence of the Chinese royalty they once accompanied, Shih Tzus believe everyone exists to admire them. Their name literally means “little lion,” though their ferocious qualities end at their fierce determination to be petted by everyone they meet.
