Service dogs hekp people with disabilities, performing tasks like guiding the blind or spotting medical issues.
If you watch a calm, focused dog in blue, it’s best not to pet or distract them. Therapy dogs, who comfort people in places like hospitals, may also wear blue, but they don’t have the same public access rights.
However, some pet owners simply select blue for its aesthetic appeal. Knowing gear colors helps enhance respectful communication with working dogs.
Other colors can also deliver meaning: yellow often means a dog needs space, red might signal “Do Not Pet,” and green may implay a friendly or in-training dog. So, next time you see a dog in blue, check the context—it might be on a job, or just looking good.
