Overstimulation is one of the most common reasons dogs struggle with behaviour, particularly in busy environments, group classes, or after exciting walks. It happens when your dog has taken in more information than they can comfortably process.

When this happens, their ability to think clearly drops—and behaviour often follows.

Common signs of overstimulation include:

• Sudden bursts of energy (zoomies)

• Barking, lunging, or mouthing

• Ignoring cues they usually respond to

• Sniffing excessively to disengage

• Yawning, lip licking, or shaking off

• Struggling to settle, even when tired

These behaviours are often misunderstood as “naughty” or “not listening,” but they’re usually a sign your dog is overwhelmed.

Triggers can include:

• Busy environments

• Too much social interaction

• Long or highly stimulating walks

• Training sessions that go on too long

What can you do?

• Lower the intensity of the environment

• Give your dog breaks before they reach their limit

• Focus on calm activities like sniffing or mat work

• Keep training sessions short and achievable

Recognising these signs early allows you to step in before your dog tips over into overwhelm. ✅
