Extinction Burst

What it means

When a behavior that used to work suddenly stops earning a reward, dogs often "try harder" for a short period before giving up, a normal and expected phase of extinction rather than a sign the plan isn't working. Recognizing an extinction burst for what it is (and holding steady through it) is often the difference between a behavior fading out and it getting accidentally reinforced at a higher intensity.

A real example

A dog that used to get picked up when it pawed at its owner's leg starts pawing harder and more insistently for a few days once pawing stops working, before it tapers off completely.

A worked example

Zara used to throw a toy whenever her dog barked. When she stopped, the barking got louder for three days. She stayed consistent, rewarded the dog for dropping the toy quietly, and by the end of the week the barking almost disappeared.

Signs it is working

• The behavior suddenly gets louder, longer or more frequent.
• The dog tries new variations of the behavior.
• It fades within days when you stay consistent.

What it is not

It does not mean the method is not working. It is often the opposite: a sign the dog has noticed the change.

Why it matters

Many owners give in during the burst and teach the dog that louder and longer works. Knowing it is temporary keeps you consistent at the exact moment it matters.

How to use it

1. Decide before you start that you will not give in, even if the behavior gets more intense.
2. Keep rewarding the alternative behavior you chose, so the dog has a way out.
3. Stay calm. Raised voices can become a new reward for some dogs.
4. The burst usually fades within days. If it gets unsafe, adjust the setup rather than rewarding it.

What if I give in once during a burst?

The behavior becomes harder to remove, because the dog learned that persistence works. You can still fix it, but expect a longer path.
