Chihuahuas may be a toy dog breed, but their personalities are enormous. These loving dogs are fiercely loyal to their humans, and it is this limitless devotion that may make some people curious if Chihuahuas can be good service dogs. Sure, they’re tiny, but can their big temperaments make up for their small stature?

Chihuahuas can absolutely become service dogs, but they won’t be suitable for every person needing a service dog. Read on to learn more.

What Is a Service Dog?

According to the Americans with Disabilities Act, service dogs have been, “individually trained to do work or perform tasks for a person with a disability.”1 These dogs are considered working dogs, not pets.

Dogs whose primary purpose is to provide comfort and emotional support to their handler will not qualify as service dogs.

What Kind of Work Can Chihuahuas Do?

When most people think of service dogs, they think of larger breeds like Labrador Retrievers and German Shepherds. While it’s true that bigger pups are capable of accomplishing more tasks, that doesn’t mean that Chihuahuas can’t do meaningful work as service dogs.

Although Chihuahuas may not be able to pull wheelchairs or offer balance support, there are many tasks they can be trained to perform successfully.

Chihuahuas can work as:

  • Epilepsy alert service dogs.
  • Diabetic alert service dogs.
  • Hearing service dogs.
  • Psychiatric service dog.

What Tasks Can Chihuahuas Perform?

Chihuahuas can perform a number of tasks, depending on what type of service dog they’re trained to be. These tasks can include:

  • Tactile stimulation and deep pressure stimulation: Using pressure through tugging, licking, or nudging to “ground” their handler and help them stay present.
  • Alerting: Notifying their handler of oncoming “episodes” (e.g., low or high blood sugar, seizures, etc.), notifying hearing-impaired handlers of sounds, allergen notification, intruder notification, etc.
  • Retrieving: Bringing their owner medication or other small objects.
  • Reminding: Prompting their handler to take medication.
  • Waking: Waking up their handler if they suffer from night terrors.
  • Interrupting: Interrupting repetitive behaviors.

What Can’t a Chihuahua Do as a Service Dog?

As we alluded to above, some tasks are impossible for Chihuahuas because of their size. This can include things such as:

  • Serving as a sturdy weight for their handlers to lean upon for support.
  • Physically guiding their handlers around obstacles or in public.
  • Pulling wheelchairs.
  • Retrieving large or heavy items.
  • Pulling the handler to change positions.
  • Answering doors.
  • Carrying grocery bags or purses.

Can All Chihuahuas Be Service Dogs?

Not every Labrador Retriever or German Shepherd makes a good service dog, and the same applies to Chihuahuas.

Each dog needs the right personality to become a suitable service dog. While Chihuahuas are generally intelligent and trainable, this isn’t the case for every dog. Some are downright stubborn and feisty.

The best service dogs are:

  • Intelligent
  • Trainable
  • Gentle
  • Calm
  • Desensitized to distractions.
  • Eager to please.

While Chihuahuas can absolutely check all of these boxes, it may not be the case for every Chihuahua.

Can I Train My Chihuahua Myself?

Theoretically, you can train your Chihuahua yourself, as the ADA does not require any professional training program to be completed for a dog to earn the service dog designation.

However, your pup will need to have an extensive skill set to earn the title of “service dog.” Without undergoing focused training to perform specific tasks to assist you, your dog will not be considered a service dog but instead an emotional support animal (ESA). ESAs are not afforded the same “rights” as service dogs. For example, ESAs cannot accompany you in stores or public transit. So, unless you have experience in training service dogs, it’s probably best to seek the support of a professional trainer. Likewise, if you do not have a disability or medical need, you do not need a service dog.

Final Thoughts

Though they may be small, Chihuahuas can absolutely become great service dogs. Their suitability as service dogs, however, will depend entirely on their individual personalities as not every dog—regardless of breed—is cut out for this type of work.

If you’re serious about getting your Chihuahua service dog status, we recommend reaching out to a professional training service to assist you in the process.
