The Pom Terrier is a hybrid breed, resulting from the crossbreeding of a Pomeranian and a Terrier. It is known for its small size, playful nature, and a lively personality. The breed typically has a fluffy coat, perky ears, and a curious, alert demeanor.

The Pom Terrier, also known as a Pomeranian Terrier mix, is a designer dog breed rather than a naturally occurring wild species. Hence, it does not have a native region in the traditional sense. It originates from intentional breeding between the Pomeranian and various Terrier breeds, often occurring in domestic environments globally, particularly in regions where designer dogs are popular such as North America and Europe.

As a domesticated breed, the Pom Terrier thrives in human-controlled environments. They are well-suited to indoor living conditions, including apartments and houses with small yards. They require a temperate climate, avoiding extreme heat or cold, as their small size and coat may not provide adequate protection from harsh weather.

Pom Terriers occupy the niche of companion animals within human societies. They are valued for their playful and energetic nature, making them suitable for families, singles, and the elderly looking for a lively pet. Their ecological role is primarily as pets that provide companionship and require regular exercise, grooming, and social interaction.
