Additionally, it’s not necessary for a service dog to wear a service vest or coat. A vest, harness, or coat are commonly seen on service dogs, but this isn’t because they are required to wear them. Some service dogs may have their gear on because that is one way they know they are in “working” mode. There may be certain times that the dog doesn’t need to be focused on work, so their vest is removed allowing for a bit of relaxation. Another reason a service dog may have a vest on is so the public knows not to interact with the animal. Many service dog coats and vest have “do not pet” printed on them. Distracting the service dog from its work can be dangerous for the dog as well as its handler. The best practice is to simply ignore any kind of working dog, whether it is wearing a vest, coat, harness, brace, or not.
