Reading body language: know when to continue and when to stop
The program only works if you can read both animals in real time. Numbers on a plan never override the body language in front of you.
Dog: early stress and arousal signs
Watch for the escalation ladder — the earlier you interrupt it, the easier it is:
- Orienting: ears pricked toward the cat, forward lean. Normal at first; reward disengagement.
- Stiffening: the body freezes, movement gets slow and deliberate. This is your cue to add distance.
- Fixating: a hard, locked stare the dog cannot be called out of. End the session calmly — the dog is over threshold.
- Whining, barking or lunging: well past threshold. The session ended two steps ago; take a break and restart farther away next time.
Also note subtler stress signals: lip licking, yawning out of context, shaking off as if wet, and refusing treats the dog normally loves. A dog who suddenly cannot eat is too stressed to learn.
What a "soft body" looks like
The goal state is a dog with loose, curvy movement: relaxed open mouth, soft blinking eyes, weight evenly distributed, tail in a neutral sweep. A soft-bodied dog can glance at the cat and voluntarily look back at you. That voluntary check-in is the single best sign the session is working.
Cat: stress signs
- Flattened ears and whiskers pulled back.
- Piloerection — fur standing up along the spine or tail.
- Crouched, tucked posture with a rapidly twitching tail tip.
- Hiding, refusing food, or freezing instead of exploring.
- Hissing, growling or swatting means the cat was pushed well past comfortable distance.
A comfortable cat moves through the room at normal speed, eats, blinks slowly and shows curiosity from its chosen vantage point.
When to stop a session
End the session — calmly, never as punishment — when any of these appear:
- The dog fixates and cannot respond to their name.
- Either animal refuses high-value food.
- The cat hides or the dog whines persistently.
- You feel yourself tightening the leash to hold the dog back.
Stopping early is never a failure. Ending on a calm rep is exactly how the next session starts better.
