If you spot a dog wearing blue gear like a vest or leash, it’s often a sign that the dog is a service animal or in training. While there’s no official color standard, blue is commonly used for dogs assisting people with disabilities. These dogs are working and should not be distracted or approached.

Service dogs perform essential tasks for individuals with various disabilities, and interrupting them can be dangerous. Blue gear may also be seen on service dog trainees or therapy dogs. However, it’s important to note that therapy dogs do not have the same legal access rights as service animals under the Americans with Disabilities Act. Sometimes, a dog wearing blue simply reflects the owner’s color preference and has no special designation. That’s why it’s always best to observe the dog’s behavior and any labels on its vest, rather than relying on color alone.

Different vest colors can carry other meanings. Yellow usually signals that the dog needs space, which could mean the dog is anxious, reactive, or in recovery from training or trauma. Giving space shows respect and ensures everyone’s safety. A red vest or leash typically means “Do Not Pet.” This may indicate the dog is working or doesn’t handle interaction well. Ignoring this cue can interfere with the dog’s responsibilities or upset its focus.

Green is often used for dogs in training or dogs that are friendly while working. These animals may be learning how to interact in public or performing a job but remain approachable in certain situations. Being aware of vest colors and their potential meanings helps the public respond appropriately to working dogs. Respecting these cues ensures the safety and effectiveness of service and support animals in public spaces.
