Does Blue Gear Mean the Dog Is a Service Animal?
In many cases, yes—blue gear is commonly used to indicate a service dog or a dog in training. While there is no universal or legally enforced color code for working dogs, blue has become a widely recognized choice among service dog handlers and training organizations.

Service dogs are highly trained animals that assist people with disabilities. They help with a range of tasks—from guiding individuals who are blind to detecting medical episodes like seizures or low blood sugar. If you see a dog in blue and they’re focused, walking calmly, or ignoring distractions, they may be working. It’s best not to pet or approach without permission.

What About Therapy Dogs?
Some therapy dogs—those who visit hospitals, schools, or nursing homes to provide comfort—also wear blue. However, the gear color varies by organization. Therapy dogs do not have the same public access rights as service animals, but they are trained to be calm and friendly in a variety of environments.
