Tiny signs your reactive dog is telling you something… before the barking even starts!
Most people notice the reaction... the barking, lunging, spinning, growling, pulling, but by then, your dog has usually been communicating for a while.
Here are some of the tiny things I pay attention to first 👇
👉 They suddenly stop sniffing.
A dog who was happily investigating the ground and then abruptly lifts their head and scans the environment has noticed something.
👉 Their mouth closes.
They might have been panting softly a second ago, then suddenly their mouth is shut and their face looks more still.
👉 Their walking speed changes.
They might slow right down, start creeping forward, or suddenly speed up and pull with much more purpose.
👉 Their ears change position.
Maybe they prick forward, flatten back, or become much more fixed towards one direction.
👉 They stop taking treats as easily.
Not necessarily refusing completely, but chewing more slowly, spitting food out, or taking it and immediately staring back at the trigger.
👉 Their body gets taller and more forward.
Weight shifts towards the front legs, neck extends, tail position changes, and suddenly the whole dog looks more “ready”.
👉 They stop checking in with you.
A dog who was glancing back at you regularly suddenly becomes completely locked onto what is ahead.
👉 They shake off when nothing obvious happened.
That full-body shake can sometimes appear after a stressful moment or after they have managed something difficult.
👉 They start scanning instead of moving naturally.
Their head moves from side to side, they keep looking behind them, or they appear to be searching for something before you have even spotted it.
👉 They can do the cue… but it looks different.
Your dog might technically sit, but their body is stiff, they are staring past you, and they are clearly not relaxed.
If we can notice the tiny changes before the explosion, we have a much better chance of changing what happens next.
Sometimes the most useful part of reactivity training is not teaching another cue.
It is learning to notice the moment your dog starts saying.... “this is getting harder for me.”
