Build the tasks that silence the noise.

Before specialized tasks, your dog needs a bulletproof obedience foundation and a clear communication system. Phase 1 establishes the request-response-reward chain your entire PSD career will run on.

• Build a clear bridge signal (clicker or marker word) before any task training. Precise timing matters more in PSD work than almost any other discipline.
• Deep pressure therapy is taught in this phase as a shaped behavior — never forced or lured. The dog offers the behavior willingly, incrementally, through your reinforcement of small steps toward the final task.
• Heel position work gets extra emphasis here — for public access, your dog must stay in position under stress. A PSD that wanders is a liability, not an asset.
• Establish a solid "place" behavior (mat or bed) — this is the psychiatric equivalent of a crate: a dog who can hold place can handle most crisis situations from a calm, settled state.

• Skipping to tasks before the dog has fluent sit/down/stay/heel. Tasks built on shaky foundations fail when needed most — which is exactly when you can least afford failure.
• Rushing DPT — if the dog doesn't offer the behavior willingly, you've trained compliance, not a task. Compliance fades under stress. Shaped behaviors hold.
• Working in low-distraction only. By end of Phase 1, the dog should perform all foundation behaviors in at least 3 different locations with mild background distraction.

Phase 2 trains the specific interrupt and alert behaviors that turn your dog into a psychiatric service dog. Each task is taught as a distinct, named behavior — so you can cue it when needed, and the dog can offer it when they detect distress.

• Anxiety interrupt starts with a nose bump to the hand — easy to shape, impossible to fake. Build from there into a full interrupt sequence that breaks dissociation or anxiety spirals.
• Nightmare interruption is trained while you're awake first — the "find and wake" sequence needs 100+ reps in controlled conditions before nighttime deployment. The dog must know the behavior before you need it at 3am.
• Grounding sequence is trained as a chain: approach → contact → maintain → release on cue. Don't skip the release training — a dog that doesn't have a clean release creates its own problem in public settings.
• Crowd blocking is taught in increments: body awareness first, then positioning relative to the handler, then holding position while others move around both dog and handler.

• Training alert behaviors before a solid attention heel — a PSD must work next to you, not in front of or behind. Position is not optional.
• Reinforcing unsolicited pawing or nudging — the alert must be clean and cued, or offered in response to genuine handler distress signals. Random nudging for attention is a different behavior entirely and erodes task clarity.
• Introducing real-world distress too early. Phase 2 is controlled training environments only — you're building the behavior pattern, not testing it under fire.

Phase 3 takes everything your dog knows into the real world. This is where most PSD training programs fail — they teach tasks at home and call the dog trained. This phase is specifically designed for PTSD-specific public access challenges.

• Start with low-stakes public environments (quiet hardware stores, libraries, off-peak grocery stores) before high-trigger environments. There is no shortcut through this progression.
• Proof crowd blocking specifically in your trigger environments — the dog needs to know where to position for your particular threat responses, not just a generic "stand beside me" approximation.
• Practice the "exit sequence" — a cued behavior that tells the dog you're leaving an environment. Dogs who learn exit cues stay calmer during your stress responses because they know what comes next.
• Carry high-value reinforcers in public at all times during Phase 3. You are still training. Do not expect performance for free in environments where you haven't yet paid for it.

• Taking the dog to public places before Phase 2 tasks are rock solid under distraction. A half-trained PSD in a triggering environment creates stress for both handler and dog — and erodes the task behaviors you worked to build.
• Letting the dog be petted by strangers during task training. Once a dog starts public access training, it is working — no exceptions until you intentionally signal an off-duty break.
• Not proofing for PTSD-specific triggers — loud sounds, crowds, unexpected contact from behind, uniforms, specific smells. Train through the triggers, not around them. The dog needs to perform in exactly the environments where you need it most.

Phase 4 is where you stop following a curriculum and start building a partnership. Every veteran's PTSD is different. Every dog has different strengths. This phase teaches you how to identify your specific symptom triggers, map tasks to them, and build a handler-specific protocol.

• Start with a symptom-task map: write out your top 5 PTSD symptoms, then identify one specific, trainable task per symptom the dog can perform. Vague goals produce vague results.
• Work with your mental health provider on this phase if possible — they can help identify early behavioral signs of impending episodes that your dog can learn to recognize before you consciously do.
• Train a "check-in" behavior — the dog making eye contact or physical contact on their own initiative when they detect a change in you. Many dogs begin doing this naturally; this phase teaches you to recognize, capture, and reinforce it.
• Document your dog's natural alerts — keep a log. Many dogs begin alerting before being cued once they've learned to read their handler well enough. These spontaneous alerts are data worth understanding.

• Over-tasking — a PSD with 20 tasks performs none of them reliably. Focus on 5-7 core tasks executed to an extremely high standard across a wide range of environments and stress levels.
• Not having a handler crisis protocol — what does the dog do when you are non-responsive or incapacitated? This is a trainable behavior. Train it before you need it.
• Relying on the dog instead of also working with a mental health professional. The dog is a tool — a powerful, irreplaceable one for many veterans. But therapy is the treatment. The dog and the work must exist together, not instead of each other.
