Two good tools that are not the same tool
Spend any time reading about reactivity and you will meet two acronyms again and again: LAT and BAT. Look At That and Behaviour Adjustment Training. Both are humane, evidence-informed protocols. Both work under threshold. Both have helped enormous numbers of fearful dogs. And because they are often mentioned in the same breath, it is easy to assume they are interchangeable — two names for roughly the same exercise.
They are not. LAT and BAT change behaviour through genuinely different mechanisms, and they suit different dogs, different triggers, and different moments. Understanding the difference is what lets you choose well instead of bouncing between methods. This is not about which is "better." It is about which is right for the dog in front of you.
What LAT does
Look At That, developed and popularised by trainer Leslie McDevitt as part of her broader Control Unleashed work, takes the very moment your dog notices a trigger and turns it into a cue. Your dog, at a safe distance, glances at the other dog. You mark that calm look — a clicker, or a clear "yes" — and you feed. You repeat it, again and again, under threshold.
Two things happen at once, which is part of why LAT is so effective. Operantly, you are teaching a behaviour: see the trigger, look back at the human, get a reward. The trigger becomes a cue to check in rather than to escalate. But underneath that, classically, you are running counter-conditioning — the trigger now reliably predicts good food, so the emotion attached to it softens from threat toward anticipation. The look-and-treat rhythm changes both what your dog does and how he feels.
LAT's great virtue is structure. It gives your dog an unmistakable job at the exact instant he might otherwise tip over, which is enormously reassuring for an anxious dog who does not know what to do with his fear. It is wonderfully suited to leash walks, to dogs who fixate, and to owners who find comfort in a clear, repeatable routine they can run on a pavement. The reward is food, which is easy to deliver and powerfully motivating, and the mechanics are forgiving — a slightly mistimed treat still does little harm.
What BAT does
Behaviour Adjustment Training, developed by trainer Grisha Stewart, starts from a different premise: that what a fearful dog usually wants most is not chicken but space. So BAT makes space the reward. At a safe distance, you let your dog observe the trigger and you wait — without cueing anything — for your dog to make a small, self-directed calming choice. A sniff of the ground. A turn of the head away. A soft blink, a shake-off, a glance elsewhere. The instant that calming signal appears, you reward it with the thing the dog actually wanted: you calmly move away, increasing distance, giving relief.
The mechanism here is about agency. Where LAT directs the dog ("look, then check in with me"), BAT hands the dog the steering wheel. The dog learns that he can affect his own world — that making a calm choice produces the relief he was seeking — and confidence built that way tends to be robust and self-directed, because it does not depend on the handler cueing every step. In the real world, where you cannot always click and feed on schedule, a dog who has learned to make his own good choices is a steadier dog.
BAT's virtue is exactly that durability and the calm, low-arousal state it cultivates. It is beautifully suited to set-ups where you have room and a cooperative helper, and to dogs whose reactivity is rooted in wanting distance. Its cost is that it asks more of the handler's reading skills — you have to recognise subtle calming signals and respond at the right moment — and it usually needs more space and more control over the environment than a quick LAT rep on a busy street.
Same foundation, different levers
For all their differences, notice what LAT and BAT share, because it is the part that actually matters most. Both demand that you work under threshold — close enough that your dog notices the trigger, far enough that he stays calm enough to think. Neither does anything useful if the dog is over his head. Both are patient, gradual, and built on success rather than confrontation. Both are the opposite of flooding and the opposite of correction. If you take only one thing from comparing them, let it be that the threshold, not the acronym, is the thing doing the heavy lifting.
Where they diverge is the lever they pull. LAT pulls the food lever and directs the behaviour. BAT pulls the distance lever and lets the dog choose. One is more handler-led and structured; the other is more dog-led and confidence-building.
Choosing for your dog
So which should you reach for? A few honest rules of thumb help.
If your dog is highly food-motivated, if you mostly train on leash in built-up places, if you fixate easily and need a clear routine, or if you are newer to this and want forgiving mechanics — LAT is a natural starting point. It is structured, portable, and quick to feel competent at.
If your dog's reactivity is plainly about wanting space, if you have access to room and a calm set-up with a willing helper dog or person, if you want to build durable real-world confidence, or if food in the presence of triggers tends to wind your dog up rather than settle him — BAT may suit better. It rewards the very thing your dog craves and grows independence.
And here is the part the "versus" framing obscures: most owners end up using both. Many dogs benefit from LAT on the daily leash walk, where structure and food are practical, and BAT in dedicated, spacious sessions where the dog can be given room to choose. They are not rivals to pick between once and forever. They are complementary tools, and a thoughtful programme moves between them depending on the trigger, the place, and the day. The skill is not loyalty to one method. It is matching the tool to the moment.
What does not change, whichever you choose, is the discipline underneath: stay under threshold, keep sessions short and successful, watch for the stacked-up stress that turns a good day bad, and rest your dog when he needs it. Get those right and either protocol will reward you. Get them wrong and neither will.
Mellow gives you both protocols as short, guided sessions rather than something to assemble from scattered videos. The Reactivity track walks you through Look At That — setting a working distance, marking the calm look, building the check-in, with a rep tracker so you can keep the rhythm without counting in your head — while the Engage–Disengage session brings BAT's logic to life, helping you read your dog's soft signals and reward disengagement with distance. The Learn library explains the thinking behind each in plain language, so you are choosing with understanding rather than guessing.
