When you notice a dog dressed in blue gear—whether it’s a vest, harness, or leash—it often signals that the dog is a service animal or currently undergoing training. While there isn’t a strict universal rule for colors, blue has become one of the most common choices for dogs that assist individuals with disabilities. These dogs are working, not simply walking pets, which means they should not be petted, called, or distracted while on duty.
Sometimes, blue gear may also be worn by therapy dogs or service dog trainees. It’s worth noting, though, that therapy dogs do not share the same legal protections or public access rights as service animals under the Americans with Disabilities Act (ADA). This distinction matters, especially in places where access rules are enforced.
Different vest colors can carry other important meanings as well. For instance, yellow often suggests that a dog needs extra space—perhaps because it is nervous, recovering, or reactive. Red is commonly used as a “Do Not Pet” warning, showing that the dog is working or prefers no interaction with strangers. Green gear is sometimes used for dogs in training that may be friendly, but still require permission before anyone approaches.
By learning what these colors represent, people can interact more respectfully and safely with working dogs. Paying attention to these signals protects not only the animal but also the person who relies on them for daily support and independence.
