When we avoid petting a working dog, distracting a dog in training, or misjudging a support animal as simply a pet, we’re helping that dog — and more importantly, the person they assist — do what they need to do safely.
What Other Gear Colors Can Mean (Unofficially)
In addition to blue, other colors have taken on informal meanings in the dog world:
Yellow: This often signals a dog that needs space. The Yellow Dog Project encourages owners to use yellow gear to alert others to fearfulness, anxiety, or reactivity.
Red: Frequently used for dogs that should not be petted, either due to aggression, working status, or health issues.
Green: Sometimes used to show a dog is friendly, approachable, or a service dog in training.
Orange or Purple: May be used by individual organizations or as part of alert gear (e.g., “Medical Alert Dog” or “Deaf Dog”).
Again, none of these are official — but they are becoming more widely understood among dog owners and the public.
Final Thoughts: Read the Dog, Not Just the Gear
Next time you see a dog wearing blue — or any bright color — take a second to pause. Look for labels, observe the dog’s behavior, and consider the setting.
Whether it’s a service dog guiding someone through a crowded store, a therapy dog comforting hospital patients, or a puppy working hard to earn their vest, understanding what the gear might mean helps us respect the incredible work these animals do.
And if it turns out that dog is just rocking a blue leash for style? Well, you’ve just seen a dog with good taste.
