The Chihuahua is classified within the Toy group due to its small size and companionship role. Toy dogs are generally bred to be companions, and they are characterized by their diminutive stature. The Chihuahua, in particular, is known for its lively personality and close bond with its owners, making it a popular choice for those seeking a small, affectionate pet.

The Toy group typically includes breeds that were developed primarily for companionship and have a size advantage, which allows them to thrive in environments such as apartments or homes with limited space. This classification reflects the importance of size and companionship in the breed’s purpose and development.

In contrast, the other groups listed have different purposes or characteristics. Hound dogs are often used for hunting due to their keen sense of smell and stamina. Working group dogs are generally known for their strength and skills in tasks such as guarding and pulling sleds. The nonsporting group contains breeds that do not fit neatly into other categories, often with varied purposes and characteristics. Each of these groups has distinct traits that differentiate them from the Toy group.
