Quick answer
If a dog stiffens, freezes, turns away, shows whale eye, licks lips, yawns repeatedly, or tries to leave, separate child and dog calmly. Do not wait for growling.

Green, yellow, and red signals
A relaxed dog has soft eyes, loose muscles, and the ability to leave. Yellow signals include lip licking, yawning, turning away, or low tail. Red signals include freezing, hard stare, growling, snapping, or a child blocking escape.
- Green: loose body and voluntary approach
- Yellow: avoidance, yawning, lip licking
- Red: freeze, hard stare, growl, snap
What to do immediately
Increase distance without drama. Ask the child to move away, redirect the child to another activity, and let the dog retreat to a protected rest area.
- Move the child first
- Do not punish warning signs
- Give the dog an exit
- End hugging, climbing, or face-to-face contact
What not to do
Do not tell the dog to tolerate it, hold the collar while the child approaches, or encourage the child to 'make friends' when the dog is already signaling discomfort.
- No forced petting
- No face kisses
- No sitting on or hugging the dog
- No taking food or toys from the dog
When to get help
Repeated yellow or red signals around children deserve a vet check and a certified behavior professional. Prevention is the point.
