The varying responsibilities of different types of service dogs and the need to be identified from other dogs necessitates the best quality and most efficient service vests and harnesses.

Service dogs can provide lifesaving assistance for those who need it. Making sure service dogs have the best gear to provide support to individuals who require help should be a top priority.

Service dogs, as a general category, are dogs that are specifically trained to help individuals with disabilities to live a more independent life. There is a range of disabilities that service dogs can provide assistance with, and some dogs are better suited to becoming service dogs than others.

No matter the breed of service dog, we want to make sure that they are best prepared to assist with their owner's particular needs. Finding the most appropriate service vest or harness for every service dog is our goal.

What Is a Service Dog?

A service dog is a dog that is specially trained to assist individuals with a disability. The goal of a service dog is to help their owner live a more independent lifestyle. Service dogs can assist with both physical and mental impairments.

Service dogs can be trained by professionals or by their owners. However, service dogs and their owners must obey state and federal requirements regarding the service dog’s training requirements and actions. Service dogs are trained for a specific set of tasks that prepare them to assist their owner's specific needs. See the examples below for specific tasks that dogs can be trained to perform.

Service Dog Tasks 

Guide Dogs 

For the blind or visually impaired, guide dogs are able to help their owner avoid or move around obstacles, alert their owner to stairs and other elevation changes when walking, find various objects around a location, and bring necessary objects to their owner. These dogs are trained to find exits when their owner cannot, follow specified individuals like waiters to a table, and to refuse a command if it endangers their owner.

Hearing Dogs

When their owner is hard of hearing or deaf, hearing dogs can help indicate the presence of other people to their owner, find and give objects that were dropped, carry written messages in their mouth, and indicate any moving vehicles or objects their owner may not notice visually.

General Service Dogs

General service dogs have extensive training to perform a wide variety of different tasks. These dogs can open and close doors, turn lights on or off, assist with dressing their owners, help their owners sit up properly and safely, and aid with a wheelchair set up. They can also pull wheelchairs as necessary.

They can keep their owner stable and upright, calling 911, if necessary, bark loudly and find assistance in other ways without leaving their owner. They can alert their owner to signs of low or high blood sugar and the possibility of an imminent seizure. 

Service dogs can help people with PTSD or other mental health issues by waking them from nightmares and interrupting flashbacks or self-harm tactics during anxiety attacks. They can also help their owner remember to take medications at specific times.

Types of Assistance Provided

In addition to guide dogs and hearing dogs, other specifically trained types of dogs are legally considered to be service dogs and are allowed in public places, regardless of the pet policy. It is important to note that while emotional support dogs can be extraordinarily helpful to their owner, the emotional support dog is generally not considered a legal service dog. Only psychiatric dogs are considered service dogs.

The General Service Dog

As mentioned above, there are different types of service dogs. General service dogs are trained to be helpful for a variety of specific tasks required by their owner's individual needs. The range of tasks mentioned above are the results of general service dog training. Within the category of service dogs are the following specific areas: guide dogs, hearing dogs, psychiatric dogs or dogs that have been specifically trained to sense and mitigate oncoming anxiety attacks, dogs for those who are physically impaired, autism assistance dogs, and dogs to assist individuals with seizures.

The Working Dog

Working dogs are generally employed to do larger tasks than regular day-to-day activities. The following dogs are known to be working dogs: the police dog, the military dog, the fire department dog, or dogs that are meant to detect medical conditions. To name a few specific tasks that working dogs are employed to do, there is search and rescue, explosives detection, and cancer and allergy alert tasks.

Each task has a specific dog breed or two that are best for that specific duty. There will be more on specific dog breeds below.

Therapy Dog

Therapy dogs are unlike the other dogs on this list, as they are not assigned to live with a particular individual to assist them with their daily life. These dogs travel with a human teammate, most of the time it is their owner, and they go to various locations where they have been trained to provide comfort and support. These locations are often hospitals, doctor’s offices, and mental health institutions.

Best Breeds for Service Dogs

The dog breed that is best suited to your particular needs as a service or working dog owner depends on the characteristics of the breed and your particular needs.

For working dogs, the specific tasks require different specialties in a dog. Bloodhounds are often used for search and rescue due to their keen sense of smell, thus an ability to find missing persons. In terms of explosive detection and law enforcement tasks, German Shepherds are the breed most often used by police departments. Beagles have been found to be better detectors of cancers than some medical tests. Hypoallergenic dogs like poodles are known to be excellent allergen alert dogs.

General service dogs can come in a wide variety of breeds. Dogs that are best for the service dog area are from a dog breed that is known to be friendly, calm, loving, caring, dependable, intelligent, and hardworking. The following dog breeds are popular dog breeds for service dogs: the Labrador retriever, golden retriever, poodle, German Shepherd, Burmese mountain dog, and Great Dane.

Vests and Harnesses

Dogs of all kinds, and dog owners, are often stopped on the street with requests to pet the dog. Sometimes there’s no request but simply an attempt to pet the dog. While this is dangerous in any situation, it is particularly dangerous for service dogs who need to be undistracted and alert to assist their owners as needed.

Distractions should be kept to a minimum and a vest or harness is a great way to alert people to the fact that your dog is a service dog. A vest that identifies a dog as a service dog is often enough to deter strangers from trying to let the dog and interfere with its responsibilities. Additionally, vests and harnesses make it easier for employees at public places to be aware that a person may have a disability and to make appropriate accommodations.

Another reason vests and harnesses can be great for your service dog is that, similar to a uniform for human workers, when a dog is wearing their service dog vest or harness it can increase the focus on tasks at hand. When you take the vest off of the dog, this can be a physical cue for the dog that it is more of a playtime. Having a good work-life balance is good for canines, too!

How to Size a Dog for Vest or Harness

To size a dog for a vest or harness, you will need to measure the chest girth of the dog. This measurement is the measurement around the dog’s rib cage, generally right behind its front legs.

First, make sure you have a flexible or soft tape measure. You do not want to use the type of measuring tape you would use for construction. That may give an inaccurate measurement and be potentially harmful for your dog.

Next, you will want to start the end of the soft measuring tape on your dog’s back. Wrap the rest of the tape measure around the rib cage until you make a full circle around the dog’s rib cage. Make sure that your tape measure is  around the broadest part of your dog’s chest.

Also, to make sure that you are taking the right measurement, put two fingers between the soft measuring tape that you are using and your dog. You want to ensure that the vest or harness will not be too tight and irritate your dog’s skin.

If the dog is in between sizes you should order the size above. Dog shoulder position is important to observe upon receiving the vest or harness to ensure that it fits properly. The shoulder position should not be awkward and the dog should have ease of mobility in the shoulders.
