Pugs are small, muscular dogs with a wrinkled face and curled tail. They are known for their playful and affectionate nature. Originating from China, Pugs have a distinctive short muzzle and large, expressive eyes. They thrive in human companionship and are adaptable to various living environments.

The Pug (Canis lupus familiaris) is a domestic dog breed that originated in China. It is not naturally found in the wild but was bred for companionship and has been spread worldwide primarily as a pet.

Pugs thrive in domestic environments. They are well-suited to living indoors, as they do not require large spaces and are sensitive to extreme temperatures. Pugs are susceptible to overheating due to their brachycephalic (short-nosed) structure, so they require a temperate climate or air-conditioned environments.

As a domesticated breed, Pugs do not have a specific ecological niche in the wild. They have been bred to be companion animals, thriving in human households rather than any natural ecosystem. Their role is primarily social, providing companionship and affection to their human caretakers.
