TEACHING A TRAINED ALERT:
THE SIT AT SOURCE

What a trained alert is, and why use one

When a dog finds the odor, they show you in some way. A natural alert is whatever your dog does on their own: freezing, staring, pawing, or lying down. A trained alert is a behavior you teach, like a sit, a down, or a nose touch.

Why teach one? Because it is easy to read. A dog who sits at the exact spot of the odor gives you a signal that is hard to miss. Judges and handlers can agree on it. It also gives the dog a way to say "found it" even if they are tired or distracted.

It is not a requirement. Neither AKC Scent Work nor NACSW requires a specific alert. You just have to be able to tell the judge when the dog has found the odor, and be right. Some handlers prefer to read a natural change of behavior. We cover this in reading your dog on odor. The right choice depends on your dog. Rules change, so check the rulebook of any sport you plan to enter.

Before you start

A trained alert sits on top of a strong foundation. Make sure your dog:

• Loves searching with food, in boxes and around rooms
• Has learned a target odor through pairing with food, as in our target odors guide
• Knows a reliable sit on cue
• Is comfortable working on a leash with a quiet handler

If the odor is still new, wait. A dog who does not yet understand the odor cannot signal it. The alert should come after the dog is committing to the source, not before. In our Intro to Odor class, we spend the first weeks on pairing and only then build the sit. The final two weeks shape the alert.

A step-by-step build

1. Start easy. Place a container with odor on the floor, in a plain spot. Let the dog find it.
2. When the dog's nose is at the source, wait. Do not talk. Many dogs will offer a sit while they think.
3. The moment the dog sits near the source, mark it with a quiet "yes" and deliver the reward right at the source, not from your hand.
4. Repeat several times in the same place.
5. Raise the bar. Wait a beat longer for the sit before you mark.
6. Change the location. Floor, low shelf, new room.
7. Fade the cue. The odor is now the cue. The dog sits because they found it.

Why reward at the source

Where you pay matters more than what you pay. If you reward from your hand, the dog learns that you are the source of treats. If you toss or place the reward at the source, the dog learns that the odor is the source. Over time they will stay close to the odor and go back to it.

If your dog does not offer a sit, you can use a light lure to get it once or twice, then fade the lure. Try not to repeat the sit cue at the source, or you will build a dog who waits for you. The goal is for the sit to belong to the odor.

Common problems

The dog sits away from the source

The dog may be guessing, or may be sitting where they last were paid. Make the hide easier, reward only at the source, and do not mark early. If you cannot tell exactly where the dog is sitting, set up a clear spot, such as a single box with odor, and use a video.

The dog sits everywhere

This is a false alert. The dog is trying a behavior that has paid. Go back to the basics: fewer sits, more search. Include blank searches, where nothing is hidden. Do not reward sits that are not at odor. A dog who sits in a blank area has not been paid, so the behavior fades. A better fix is to put in more real hides so the dog learns that odor, not sitting, is the reason for the pay.

The dog stands up or pops out of the sit

The dog may be eager for the reward. Reward quickly, in position, and in small steps. Ask for a hold of a second or two, then build. Use a tidy, low voice.

The dog hesitates or freezes

Some dogs, especially nervous ones, do not like sitting near odor sources or in front of objects. Try a different alert, like a nose touch or a down. Or use a natural alert. Forcing a posture makes a worried dog more worried. See our page on scent work for anxious dogs.

Choosing the right alert for your dog

Think about your dog's body and personality.

• A sit is easy and visible, but hard on some older dogs or dogs with hip pain.
• A down is calm, but takes longer and may be hard for small or arthritic dogs.
• A nose touch or stare is quiet and easy on the body, but harder for a judge or handler to see from afar.
• A paw or bark is clear but can be loud, and may build stress in some dogs.

If your dog has joint problems, check with your vet before building a sit. For senior dogs, see scent work for senior dogs. Short-nosed dogs may tire quickly when they sit and strain. Give them time.

It is fine to switch. If a sit is not working, change it and rebuild.

Handler habits that help

Your behavior matters as much as the dog's. Stay still when the dog works. Do not lean, point, or hover. When the dog sits, do not call "alert" in a rush. Take a breath, check the dog's body, and call when you are sure.

Video your practice. It is easy to miss a late sit or a drift away from the source. See common handler mistakes for more.

Finally, keep the alert fun. A dog who has learned to show you the source has learned a conversation. Our private lessons can help you build it one step at a time.
