Toy breeds are small dog breeds that typically weigh less than 12 pounds. They are known for their compact size, making them popular choices for people living in apartments or smaller homes. Despite their small stature, toy breeds often have big personalities and can be very energetic and playful. Common examples of toy breeds include the Chihuahua, Pomeranian, and Yorkshire Terrier. These dogs are often affectionate and enjoy being close to their owners. Due to their size, they require careful handling and supervision, especially around young children and larger pets.
