If you notice a dog wearing blue gear such as a vest or leash, it often indicates that the animal is a service dog or one in training. While there is no universal rule about vest colors, blue has become a common choice for handlers of service animals. These dogs provide vital assistance to people with disabilities, and distracting them can interfere with their work and even put their handler’s safety at risk.

Blue gear may also be worn by service dog trainees or therapy dogs. However, it’s important to distinguish between the two. Service dogs are protected under the Americans with Disabilities Act (ADA) and have legal access to public spaces. Therapy dogs, while valuable in providing emotional comfort in hospitals, schools, or nursing homes, do not share the same legal rights as service animals.

That said, not every dog in blue gear is performing a special role. Sometimes owners simply choose the color for personal preference, and it carries no particular meaning. Because of this, observers should not rely on color alone but instead look for identifying patches, wording on the vest, or observe the dog’s behavior to understand its role.

Other vest colors also carry potential significance. Yellow gear is often used as a signal that a dog requires extra space. This may be because the dog is anxious, reactive, or recovering from training or trauma. Respecting this signal helps ensure safety for both the animal and the people around it.

Red vests or leashes typically convey a “Do Not Pet” message. This may indicate that the dog is working, easily distracted, or uncomfortable with outside interaction. Ignoring this cue can disrupt the dog’s responsibilities and undermine its training. By contrast, green gear is often associated with dogs in training or those considered approachable while working, though boundaries should always be respected.

Recognizing vest colors and understanding their possible meanings can help the public interact more responsibly with dogs in public spaces. Giving service animals the respect they need not only ensures their effectiveness but also protects the independence and safety of the individuals who rely on them.
