Alert barking that never stops: Figgy's story

Figgy barked at sounds his owners could not hear. A dog running that level of vigilance never properly switches off, so the baseline stays high, and it takes less and less to set off the next bark.

Figgy is a Maltese cross Poodle. His owners counted six or seven alert barks on a typical day. He was barking at sounds they could not hear, noises outside the fence line, things that registered to him but produced nothing visible to them. He was not anxious in a withdrawn way. He was alert, sharp, and determined to report everything to the household whether the household wanted the report or not.

The other presenting issue was crate resistance. Figgy would carry on in the crate, and eventually he would be let out to stop the noise. His owner knew, intellectually, that she was rewarding the demanding behaviour. The difficulty was that it had been working for so long, from Figgy's perspective, that she was up against a well-established pattern.

What alert barking actually is

Sound-reactive dogs are monitoring their environment continuously. Every noise that falls outside the category of known, predictable, and safe gets flagged, and the bark is the flag. The problem is that a dog running this level of vigilance never properly switches off, which means the baseline arousal stays elevated, which means it takes less and less to trigger a bark. The alert becomes hair-trigger because the dog is always partway up the waterline already.

This is why the pattern tends to get worse, not better, if you leave it alone. It is not a quirk to habituate out of. It is a nervous system running above the range it should, and the behaviour is the signal of that. In Figgy's case the barking also had a reward history. He barked, he got let out. He barked, someone went to check. He had no incentive to stop. The behaviour was working for him.

Why CALM was the lever for Figgy

Figgy's problem was rooted in a dog who never properly switched off, so for him the crate work was the lever, the part of the program that, once his owner held it consistently, changed the household. The rule is simple: a dog in CALM only comes out when it is settled. Not when it stops barking for a few seconds and then starts again. Settled. Still. Not demanding.

The duration in the crate was never the issue for Figgy. The consistency was. Every time the demanding behaviour got a response, it reinforced the pattern. Once the pattern stopped producing a response, it had to extinguish. That is not complicated, but it is hard in the moment, because it tends to get louder before it gets quieter. His owner was disciplined about it. Within the first few weeks, Figgy was settling faster and the alert barks at home were dropping. He started taking himself into the crate at the end of a cycle. That is a dog who has learned the crate is where rest happens, not where demanding gets results.

Reducing the input that keeps the system on alert

Part of the alert-barking problem was sensory: Figgy had a view of the street and was using it constantly, monitoring everything that moved. One of my recommendations was to reduce that access when he was out of the crate. Close the windows that gave him the patrol view. A dog who is constantly patrolling from inside the house is not resting, regardless of whether it is lying down while it does it. Reducing inputs is not deprivation. It is giving the nervous system a chance to drop.

We also worked on the alert barking directly. An interrupter was introduced at the moment of escalation, paired with redirection into PLAY. The dog learns that the sound is an opportunity to engage with the handler, not a reason to mobilise the household.

Connected, not just quiet

A few months after finishing, one of his owners left a review that described what had actually changed: the training had made Figgy a more connected dog by teaching them to read him. The word was connected. Not obedient. Not quiet. A dog alert-barking at frequencies the humans cannot detect is operating in a separate world from its people. The training did not make Figgy less sensitive to noise. It made him more oriented toward his people as the source of information about what those noises meant. When you are the reference point, the noise loses its automatic urgency.

Common questions

Why does my dog bark at noises I cannot hear?

Sound-reactive dogs monitor their environment constantly and flag anything unfamiliar with a bark. The trouble is that this level of vigilance keeps the baseline arousal high, so it takes less and less to set off the next bark. The fix is lowering the baseline, not addressing each noise.

Does alert barking get better if I ignore it?

Usually it gets worse, especially if the barking has ever been rewarded with attention or being let out. It is a nervous system running too high. Lower the baseline, remove the patrol view, and make sure the barking stops working.
