Since the United States doesn't recognize Service Dog "certifications," the only way to tell a properly trained Service Dog from a fake is by behavior. Read on to learn more about what a Service Dog should act like. Every Service Dog Team is Unique Every Service Dog team has unique abilities, needs, and work styles. No two teams possess the same training since every disability is different. What works for one team may not work for others. However, it's vital to note that every "real" Service Dog has one thing in common: they're individually trained to meet the needs of a person with a disability. This individual training specifically addresses their person's needs. The behaviors, tasks, and work the dog does for their handler aren't "natural" behaviors or things any dog could do. The training is precise and exact. The trained behaviors are on cue, reliable, and repeatable. The dog's response to the cue/command is predictable since it's a trained behavior.     As an example, a Service Dog who is trained to nudge their handler's hand when the handler becomes frozen in fear is different from a dog who naturally pushes and shoves with their muzzle. The second dog's behavior cannot be predicted and it isn't on cue. Therefore, it's not a trained behavior and does not count as a Service Dog task, even if it's helpful.   Emotional Support Is Not a Trained Task All dogs can provide emotional support. You can't train a dog to provide emotional support, however you can train a dog to provide deep pressure stimulation to ground the handler during a panic attack or to alert the handler to a person approaching from behind. These actions are then called "tasks" or "work" and can be labeled. A dog who is not trained to reliably provide tasks and/or work that help their handler do things they couldn't do on their own in response to specific cues or commands is not a Service Dog. Dogs in public masquerading as Service Dogs who aren't Service Dogs do not possess the caliber of training necessary to work calmly and reliably. Fake Service Dogs create a lot of complications for real Service Dog teams. Namely, they create suspicion and access issues for well-trained teams.
