Leave It
Overview
"Leave it" means: whatever you were about to grab or chase, disengage from it now and check in with me. Done well it becomes an almost reflexive head-turn away from temptation, which is why it's one of the most useful safety cues a dog can own — it's the difference between "ignored the chicken bone" and an emergency vet visit.
🎥 VIDEO — Leave it demo (PRIMARY) Show: handler drops a treat on the floor, says "leave it," the dog looks away to the handler and is rewarded from the hand (never the floor item). Length/shots: 20–30s. One clean rep on the floor, one with a walk-by temptation. Trainer note: stress that the reward comes from you, not the forbidden item. Attaches to the lesson's primary video.
Why it matters
Dogs explore the world with their mouths, and a lot of the world is dangerous — discarded food, medication, toxic plants, wildlife. A dog who reliably leaves it on cue is safer off-leash, calmer on walks, and easier to live with around counters and floors.
Which approach fits your dog?
Nearly every dog builds a great "leave it" on positive reinforcement — you're teaching that turning away from one good thing produces an even better thing from you. For a confident adult dog who already knows "leave it" but needs it to hold around high-value, real-life temptations (livestock, wildlife, garbage), some handlers layer in light remote-collar guidance. A young puppy, a sensitive dog, or — critically — any dog whose interest in the item is tied to guarding or fear is an R+-only dog here.
Method A — Positive Reinforcement
The goal: make "leave it" mean "look away and something better happens."
Step 1 — Trade the closed fist. Hold a treat in a closed hand. Let the dog sniff and paw; the instant they back off, mark ("yes") and reward from the other hand. Repeat until backing off is instant.
Step 2 — Add the words. Now say "leave it" as you present the fist. Reward the disengagement. The cue starts to predict "turn away, get paid."
Step 3 — Take it to the floor. Cover a treat on the floor with your hand, say "leave it," reward the look-away from your hand. Gradually uncover it, always ready to cover if the dog dives.

Alt text: "A dog looking up at its handler instead of a treat on the floor during leave-it training." Trainer note: show the hand ready to cover the item — management while the behavior is young.
Step 4 — Generalize. Practice with dropped food, toys, then outdoors with real distractions on leash. Reward heavily — you're competing with genuinely tempting things.
Step 5 — Add movement. Walk past a "planted" temptation on leash; cue "leave it" and reward the dog for walking on. This is the real-world version.
Method B — E-Collar (Remote Collar)
The honest framing. For "leave it," low-level stim acts as an interrupter/pressure the dog turns off by disengaging — useful for a fluent dog around powerful temptations where a treat can't compete (chasing livestock, scavenging carrion). It is not how you teach the cue. The best controlled e-collar trials (on off-lead recall) found reward-based training equal or better with fewer welfare risks (Cooper 2014; China 2020); there's no evidence an e-collar outperforms R+ for "leave it" either, and AVSAB recommends reward-based methods only. Offering this track at all is a stance more permissive than AVSAB's. Optional, gated, safety-first.
Use this track only if: the dog is ≥6 months, already does a fluent reward-based "leave it," is confident and stable, and ideally you have professional guidance. Otherwise → Method A.
Step 1 — Fit, habituate, find the working level. Fit the collar snug and high on the neck with both contacts on skin, and let the dog wear it (turned off) for a few days so it means nothing. Then, on a calm, undistracted dog, start at the lowest setting and step up one level at a time only until you see the first tiny acknowledgment — an ear-flick or head-turn, never a yelp or flinch. That's the working level; many dogs work at a level a person can barely feel.
Step 2 — Pair low stim with a known temptation. Set up a temptation the dog already knows to leave. As the dog orients toward it, cue "leave it" and apply a brief low tap; the instant they turn away, stim off, mark, and reward from your hand. Disengaging turns the sensation off and earns pay.
Step 3 — Fade to tone/voice. Move toward the tone or your cue alone doing the work, with stim the rare back-up.
⚠️ Safety — non-negotiable
Mild electrical stimulus, lowest effective level, always escapable — turning away ends it — and always paired with reward.
Prerequisites: ≥6 months and a fluent reward-based "leave it." Never use stim to teach it from scratch or on a puppy.
Do NOT use when the dog's interest is resource guarding or fear-based — adding pressure to guarding or fear can create aggression. That's a different lesson (see Preventing Resource Guarding #10) and often a job for a pro.
Never use stim to interrupt a dog who is already over-threshold and lunging/aggressing — get professional help.
Fit & skin care: reposition every 1–2 hours, ≤~8–12 hours wear, check the neck. STOP at any fallout.
Common mistakes
Rewarding from the forbidden item. Never let the dog get the thing they left — pay from your hand, or with a different treat.
Using "leave it" as a scold after the dog already grabbed something. It's a pre-emptive cue; for "spit it out," teach Drop It (#16).
Going straight to hard temptations outdoors before the behavior is solid at home.
(E-collar) Reaching for stim on a dog who never learned the cue, or on a guarding/fearful dog — that's how you create bigger problems.
Practice this week
Daily closed-fist and floor reps; reward the look-away every time.
One on-leash "walk past a planted temptation" rep per walk.
Build up to a dropped (safe) food item on cue.
Goal by end of week: dog turns away from a treat on the floor on a single "leave it," and walks past a mild temptation on leash.
