Can Any Dog Become a Police Dog? How Small Breeds Like Chihuahuas and Corgis Are Joining The Force

When you picture a police dog, you probably imagine a powerful German Shepherd on duty. But around the world, small and medium sized dogs like Chihuahuas, Toy Poodles, Corgis, and Beagles are proving that aptitude and training matter far more than size or breed label.

If dogs had a "dream jobs" ranking, becoming a police dog would almost certainly be near the top. Many pet parents picture a sleek German Shepherd or Doberman when they think of a K9 partner, but modern police work is changing, and so are the dogs who serve.

Today, breed rules are gradually loosening in many regions. In Japan and abroad, small and medium sized dogs such as Chihuahuas, Toy Poodles, Corgis, and Beagles are now working as official police or detection dogs. This shift reflects a growing focus on each dog’s individual strengths rather than a narrow list of “approved” breeds.

In this guide, you’ll learn how police dog systems work in Japan, which breeds are commonly used, how small dogs are being recruited, and what it actually takes for a privately owned dog to qualify. You’ll also see real examples from Japan, China, and the United States that show just how diverse modern working dogs have become.

How Police Dog Systems Work In Japan

In Japan, police dogs fall into two main categories. Understanding this structure helps explain why some dogs are raised within the police system, while others start out as family pets.

There are two systems:

• Directly Managed Police Dogs
  These dogs are owned, trained, and managed directly by the police. They are usually raised and handled within official facilities and are often selected from traditional working breeds.

• Commissioned Police Dogs
  These are privately raised dogs that pass an official evaluation and are then commissioned by the police to assist with specific tasks. They typically live with their pet guardians and are called into service when needed.

Directly managed police dogs in Japan are still most often drawn from classic working breeds such as German Shepherds. These dogs are expected to perform demanding tasks like tracking, scent discrimination, and public order support.

Commissioned police dogs, on the other hand, are where things are changing most rapidly. Because they are recruited from the general public, pet parents who invest in solid training can now aim for their dogs to support real investigations and search operations.

Each prefectural police department holds its own annual evaluation. If a dog passes, they are commissioned as a police dog for a set period, usually one year. During that time, they may be called upon to help search for missing people, locate evidence, or assist in disaster zones.

Which Dog Breeds Can Become Police Dogs

Many people assume there is a strict, unchangeable list of breeds that can work as police dogs. In reality, there are recommended breeds, but the rules are becoming more flexible, especially for commissioned dogs.

Officially Designated Breeds And Growing Exceptions

The Japan Police Dog Association currently designates seven primary breeds as standard police dog types:

• German Shepherd Dog
• Labrador Retriever
• Golden Retriever
• Doberman
• Boxer
• Airedale Terrier
• Rough Collie

These breeds are considered especially suitable for advanced scent work such as tracking footprints and discriminating between different human odors. As a result, directly managed police dogs are still selected almost exclusively from this group.

However, rules for commissioned police dogs are set by each local government, and more prefectures are choosing not to restrict by breed. This shift reflects a growing recognition that many breeds, including mixed breeds, can excel in scent work and search tasks when properly trained.

For example, the Kanagawa Prefectural Police clearly state that eligible dogs are simply:

Dogs with the ability to search for people or objects. (Breed does not matter.)

In contrast, some prefectures such as Akita historically limited candidates to the seven designated breeds. Even there, though, recent policy changes have begun to remove strict breed requirements, opening the door for a wider variety of dogs.

For pet guardians, this means that if your dog is healthy, motivated, and enjoys training, it may be worth checking your local rules rather than assuming they are ineligible based on breed alone.

The Rise Of Small Breed Police Dogs

Data from Japanese news outlets show that the range of breeds serving as commissioned police dogs is expanding quickly.

According to reporting by Asahi Shimbun, the number of breeds registered as commissioned police dogs has grown significantly:

• 2015 18 breeds
• 2024 31 breeds

That’s roughly a 1.7-fold increase in just under a decade, and many of the new additions are small or medium sized companion breeds.

This trend reflects a broader understanding in working-dog training: size is only one factor. For many tasks, qualities like scenting ability, focus, resilience, and a stable temperament around people matter far more than height or weight.

How A Privately Owned Dog Can Become A Police Dog In Japan

If you are a pet parent in Japan and wondering whether your dog could qualify, the basic pathway is relatively clear, even though the details vary by prefecture.

A typical process looks like this:

1. Apply to your prefectural police evaluation
   Each prefecture announces dates and requirements for its commissioned police dog trials.

2. Submit required documents
   This usually includes an application form, a written pledge to follow rules, and sometimes proof of previous training or test results.

3. Attend the evaluation on the designated day
   Dogs and handlers are tested at a specific venue under standardized conditions.

4. If the dog passes, receive a one year commission
   The dog is then registered as a commissioned police dog and may be called to assist in real operations.

Evaluation content differs by region, but commonly includes:

• Obedience work such as recalls, heeling, and stays
• Tracking of human footprints or scent trails
• Scent discrimination to identify a target odor among several options
• Search tasks for people or objects in a defined area

Some prefectures also require proof of prior training. For example, Aomori Prefectural Police list passing a basic training test from the Japan Police Dog Association or the Japan Shepherd Dog Registration Association as a condition for entry. For search specific categories, a recognized rescue dog qualification may also be accepted.

For motivated pet guardians, this means that investing in structured obedience and scent work training is essential. Working with an experienced trainer who understands police or search dog standards can dramatically improve your dog’s chances of success.

The Unforgettable Corgi Police Dog In China

One of the most widely shared examples of a small working dog comes from Shandong Province in China. Social media users were captivated by images of a Corgi police dog being carried on the handler’s back during patrols.

This Corgi, named Fuzai, has been trained by the local Public Security Bureau as a working detection dog. Reports describe Fuzai assisting with explosives detection and event security, demonstrating that even a short legged, long bodied breed can excel when matched to the right tasks.

In tight or low spaces, a compact dog can move more easily than a large one. In addition, at public events involving children or older adults, a small, friendly looking dog can help reduce anxiety and encourage positive interactions with law enforcement.

Small Breed Police Dogs In Japan

Japan has its own memorable examples of small dogs serving as police partners.

• Momo the Chihuahua, Nara Prefectural Police
  In 2010, a Chihuahua named Momo passed the police dog evaluation in Nara. Weighing only about 3 kilograms, she still completed her duties with determination, challenging stereotypes about what a police dog should look like.

• Hanna the Toy Poodle, Okayama Prefectural Police
  In 2021, a Toy Poodle named Hanna became the first of her breed to be recognized as a police dog in Okayama Prefecture. News coverage highlighted her cheerful expression as she ran through the evaluation exercises, showing that enthusiasm and focus can matter more than size.

These cases are more than feel good stories. They illustrate a practical point for pet guardians and trainers: when selection is based on performance, many breeds can contribute meaningfully to search and detection work.

Beagles On Duty In The United States

The trend toward diverse working dogs is not limited to Japan and China. In the United States, Beagles have long been valued as detection dogs, especially in airports.

The United States Department of Agriculture (USDA) operates a program known as the Beagle Brigade. This unit is made up of Beagle detection teams deployed at airports and other ports of entry.

Their primary mission is to detect prohibited agricultural products, such as certain fruits, vegetables, and meat or dairy items that could introduce pests or diseases. Beagles are particularly well suited to this role because they are:

• Highly motivated by food rewards
• Possessed of an excellent sense of smell
• Generally gentle and approachable in crowded public spaces

For travelers, a Beagle calmly sniffing luggage is far less intimidating than a large, imposing dog. For handlers, Beagles offer a balance of drive, trainability, and a size that is easy to manage in busy terminals.

Why Breed Matters Less Than Aptitude

Many pet parents still believe that only a few large, powerful breeds can ever become police dogs. Modern practice tells a different story. Around the world, a growing variety of breeds and mixed breeds are being evaluated on their individual abilities rather than their appearance.

Breed does influence certain tendencies. For example, some breeds may have stronger natural tracking instincts, while others may be more sensitive or more independent. However, what ultimately determines success as a police or detection dog is a combination of aptitude, health, temperament, and consistent training.

If you find yourself wondering, "Could my dog do this?" consider the following:

• Temperament Does your dog recover quickly from new experiences and show curiosity rather than fear?
• Motivation Is your dog eager to work for food, toys, or praise over sustained periods?
• Health and structure Is your dog physically sound enough for the tasks required in your region’s program?
• Trainability Does your dog enjoy learning and respond well to clear, positive guidance?

If the answer is yes to many of these questions, your next step is simple but important. Check the latest recruitment and evaluation guidelines from your local police or relevant working dog organization. Requirements can change, and you may discover that your dog is more eligible than you expected.

Exploring A New Path With Your Dog

The evolving world of police and detection dogs shows that there is no single "ideal" breed for every task. From German Shepherds and Labradors to Chihuahuas, Toy Poodles, Corgis, and Beagles, dogs of many shapes and sizes are now contributing to public safety.

For pet guardians, this opens up new possibilities. With thoughtful training, expert guidance, and a realistic understanding of your dog’s strengths, you and your dog may be able to support your community in ways you never imagined.

If the idea excites you, start by researching local programs, talking with experienced trainers, and building a strong foundation in obedience and scent work. Whether your dog ultimately becomes an official police partner or simply enjoys the mental enrichment of detection games at home, investing in their potential strengthens your bond and enriches their life.

Your dog’s future is not defined by breed alone. With the right support, their unique talents can lead to a rewarding journey for both of you.
