2. Russian Toy

Standing up to 11 inches tall and weighing a maximum of 6.5 pounds, the Russian Toy is one of the more recent breeds to gain full recognition in the United States. They feature long, lean legs and fine bone structure, making them appear incredibly delicate.

Originally bred as prized companions for Russian aristocracy, these dogs thrive on human interaction and boast an energetic, cheerful disposition. They can have either a smooth coat or a long coat adorned with distinct, elegant fringes trailing from their ears.
