If you spot a dog wearing a blue vest, leash, or bandana, it’s likely more than just a style choice. Blue gear often signals that the dog is a service animal or in training.
While there’s no official color code, blue is commonly used to identify service dogs, which are trained to assist people with disabilities—guiding the visually impaired, detecting medical episodes, retrieving items, or providing mobility support.
If the vest says “Service Dog” or “Do Not Pet,” respect that the dog is working. The best response? Give it space and don’t distract it.
