Service Dogs

As a community of animal lovers, we all know how difficult it can be to resist the urge to cuddle a service dog. Dogs are lovable enough, but there is something extra cute about an official vest and a dog performing a service.

There are some fundamental reasons behind the well-known rule not to pet service dogs as hard as it may be. Don’t worry, it’s not uncommon to not know all the reasons behind this rule, so this article will take you through the essential reasons to ensure you show respect and act appropriately around service dogs.

The 3 Reasons Why You Can’t Pet Service Dogs

We can clearly see the various uses and importance of service dogs to enable and support many to live full and active lives, so why can’t we appreciate them by petting them?

1. It’s Distracting

First and foremost, petting a service dog can be distracting to a dog that is actively working with their handler. Service dogs are trained to perform specific tasks that can assist with safety, mobility, or medical conditions, and distractions can interfere with their ability to perform those trained tasks.

Even the most well-trained dog can succumb to being distracted easily by the actions or attention of someone around them. Interacting with a service dog may take their mind off their tasks. Even momentarily lapses in concentration can have serious consequences for the handler.


2.It Interrupts Their Work

Service dogs are trained to stay closely connected to their handler while they work. Many tasks rely on the dog carefully observing their handler’s movements, body language, and cues from the surrounding environment.

When someone approaches and pets a service dog, it can interrupt this working connection. Even a short interaction may delay the dog’s response to a cue or prevent them from noticing something important.

Service dogs are specifically trained to ignore distractions and prioritize their handler. Interacting with them while they are working can interfere with that training and make it harder for them to perform their role effectively.

3. It’s Disrespectful (and Illegal!)

As a rule, petting another person’s dog without permission is disrespectful and dangerous. Unsolicited touching of a dog can cause them to become stressed, anxious, or distract them from training or tasks.

You should ask their owners before petting an ordinary pet, but there is little point in asking to touch a service dog. Service dogs will be wearing a vest or patch that indicates they are a service dog and not to be touched. Not respecting this boundary is disrespectful and may endanger the handler.

In some states, such as Arizona, laws make it illegal to intentionally interfere with a service animal, and the consequences can include criminal charges such as misdemeanors or, in certain circumstances, more serious offenses.

Types of Service Dogs

A service dog is defined as any animal trained to work and perform tasks to assist individuals with disabilities. Because they help people with disabilities, service dogs are legally allowed to accompany their handlers in most public places.

Service dogs perform important assistive tasks for many disabilities. Some of the most common types of service dogs include:

  • Medic Alert Dogs - Trained to detect physiological or behavioral changes in their handler that may be associated with certain medical conditions. This may include changes in blood glucose levels or the onset of seizures in dogs specifically trained for those tasks.
  • Guide Dogs - Act as guides for the visually impaired and assist them in navigating the world around them.
  • Mobility Support Dogs - Some dogs have been trained to help those with mobility issues move around and can be used for balance, retrieving objects, support, and wheelchair assistance.
  • Psychiatric Support Dogs - These dogs’ main task is to assist with psychiatric disabilities and support their handler’s functioning and safety, but can also perform trained tasks, including retrieving medication and interrupting or redirecting certain harmful behaviors.

Service Dog Etiquette

None of us has intentions to disrupt a service dog while they are working or disrespect a service dog’s handler. Beyond the no petting rule, there are many other guidelines for behaving around a service dog that you may be unaware of.

Getting a good idea of proper service dog etiquette will mean you will be respectful and helpful to service dog handlers who are constantly dealing with inappropriate behavior around their dogs.

Familiarize yourself with these service dog etiquette tips with this what-not-to-do list:

  • Do not touch or pet
  • Do not talk to them or call their name
  • No eye contact - even this act is a communication to a dog and can be distracting
  • Don’t offer them food, treats or toys
  • Do not attempt to taunt them or get their attention
  • It’s rude to ask what tasks the service dog is trained to perform
  • It’s illegal to ask for service dog documentation, as it goes against the owner’s privacy

Instead, practice these behaviors:

  • Give the service dog space
  • Stay relaxed and calm
  • Completely ignore the existence of the dog - even if it attempts to interact with you
  • Keep your dog away from a service dog
  • If you find an unattended service dog, look for the handler nearby or alert staff if assistance may be needed if the dog is signaling distress

Final Thoughts

These rules will ensure you show the deserved respect to both a service dog performing important trained tasks and the handler who relies on the dog’s assistance. There are plenty of unemployed dogs who want nothing but petting. Direct your loving energy toward them and perhaps visit local shelters to offer companionship to dogs awaiting families.
