Marker Training for Dogs | How to Use a Marker Word

A marker word helps your dog understand exactly which actions and choices are correct and earned the rewards.

Marker Training for Dogs: 

Find your moment of “Yes” 🐾

Marker training is one of the best ways to communicate with your dog.
A marker is a short word, sound, click, or signal that tells your dog:“That exact moment is what I liked. A reward is coming.”
It helps your dog understand which choice worked, so they can repeat it again in the future.
Whether you are teaching recall, loose leash walking, polite greetings, calm behaviour, puppy skills, or helping your dog around triggers, a clear marker can make training easier for both of you.

What is a marker in dog training?

A marker is a clear signal that tells your dog the exact moment they made a good choice.
Most people use a short word like: “Yes”
Some people use a clicker, a tongue click, a thumbs-up, or another consistent sound or signal.
The marker works like a camera shutter 📸 It captures one tiny moment and says: “That. That is the thing I liked.”
For example:Your dog sees another dog.Instead of pulling forward, they glance back at you.You say “Yes.”Then you reward them and, when appropriate, help them move towards meeting a friendly dog.
Over time, your dog learns to check in with you first when they see another dog, because checking in becomes the most rewarding way forward.
This is why marker training is such an important foundation for positive reinforcement dog training. It helps your dog understand which choices work, so they can repeat those choices again in the future.

Why marker training works

Dogs are always learning, but they do not automatically know which part of their behaviour we liked.
Your dog might sit, look at you, wag their tail, sniff the ground, shift their body, then receive a treat.
❌ Without a marker, they may think: "I got food, but I’m not sure why.”
✅ With a marker, the message becomes clearer: “The moment I looked at you is what worked.”

Clarity helps your dog learn faster and with less frustration.

It also helps prevent some of the common problems that happen when training is unclear. Without clear feedback, dogs may start guessing. They might sit, jump, bark, paw, spin, mouth, stare at your treat pouch, or offer lots of random behaviours because they are trying to work out what earns the reward.
A clear marker helps your dog understand: “This specific choice is what worked.”
That means your dog is more likely to repeat the behaviour you actually want, instead of guessing, getting frustrated, or only responding when they can see food in your hand.
This is one of the reasons marker training is so useful. It helps shift training away from bribing your dog with visible food and towards clear communication.
The food, toy, sniff, praise, or access comes after the behaviour and marker.

The order becomes:

Behaviour → marker → reward
Not:
Food appears → dog guesses → reward happens
When your dog understands this pattern, they learn that their choices make good things happen. That makes training clearer, calmer, and much easier to use in real life.

Quick comparison

Without a marker	With a marker
Your dog may guess what earned the reward	Your dog knows the exact moment that worked
Training can feel confusing for you and your dog	Training becomes simple and clearer
Your dog may offer random behaviours	Your dog learns which specific choice to repeat
Food can accidentally become a bribe to get behaviour	Dog learns Rewards come after the behaviour and marker
Rewards may arrive too late	The marker bridges the gap
Training can become hard, the dog may get frustrated, and disengage from the training process.	Training can be made simple, the dog gets clearer feedback and training becomes engaging

Trainer Tip 💡

Think of your marker like adding money into the training bank.
At first, a word like “Yes” is just a sound.
But when you say “Yes” and then consistently follow it with something your dog values, that word starts to mean something.
Over time: “Yes” = good things are coming.
That is when your dog starts listening for it.Their ears tune in.Their brain starts to recognise it.Their choices become easier to guide.
The more consistently you mark the behaviours you like, and reward the dog for those behaviours the more valuable and useful your marker becomes.

How to teach your dog a marker word

Step 1 — Teach your marker word

I recommend starting with the word “Yes.” It is short, easy to say, and works well in everyday training.

Start somewhere quiet and easy, like your lounge room, backyard, or a calm space with very few distractions.

Grab some of your dog’s favourite treats and place them somewhere your dog cannot reach, but where you can easily reach them. (At the start, food is usually easiest because it is quick, clear, and repeatable.)
Wait until your dog is nearby and calm.
Say "Yes" Then quickly reach for a treat and deliver it to your dog. (Ideally, at this stage the treat should arrive within 1–2 seconds after you say the marker word)
Repeat this 5–10 times.

🚫You are not asking your dog to sit, stay, lie down, or perform any behaviours at this stage. Keep it easy.You are simply teaching your dog: “When you hear "YES", something good follows.”

Trainer Tip 💡

The order is: Marker → reward Not Reward → marker. 
Avoid holding the food in your hand or reaching for it before you say the word "YES"
Try not to repeat the marker word over and over.
Avoid using lots of extra words shortly before or after the marker.

For example, instead of saying: “Good girl, yes, good dog, yes, good job! Yes you're so clever”
Keep it clean and simple: “Yes.” → reward
This helps your dog understand that the marker word itself is the important piece of information.
Short, successful sessions are better than long sessions where your dog becomes tired, distracted, or frustrated.

Clicker version

If you are using a clicker, the process is the same:
Click → reward
The click works just like the word “Yes.”
The important part is that the marker comes first, and the reward follows.

Step 2 — Start marking real choices

Once your dog understands that the marker predicts a reward, you can start using it for behaviours you like.
You are no longer just saying “Yes” → treat to build the marker.
You are now using the marker to tell your dog:
“That choice worked. Let’s make that happen again.”
The reinforcement should match what your dog wants in that moment.
Sometimes that might be food.Sometimes it might be moving forward.Sometimes it might be sniffing.Sometimes it might be space from something they are unsure about.Sometimes it might be calm affection or access to something they enjoy.

This is where marker training starts becoming really useful in real life. 
Instead of asking your dog to guess what to do, you are now giving them clear feedback in the moment.

Real-life marker examples

Real-life situation	Mark “Yes” when…	Then reinforce with…
You cue your dog to sit	Their bottom touches the ground	Food, praise, or pats
Your dog is pulling and, you slow down	The leash goes slack	Moving forward again
Your dog is walking nicely beside you	They are beside you looking forward	High value treats
Your dog is greeting you or a visitor	They are within patting range with four feet on the floor	Calm pats, attention, or praise
Your dog sees another dog	They look back at you instead of pulling, barking, or staring	Food, space, sniffing, or controlled access depending on what your dog needs
You call your dog back	They turn and move towards you	Food, play, praise, or release back to exploring
Your dog goes to their mat	They step onto the mat or lie down calmly	Food, Long lasting chew, calm praise, or quiet attention
Your dog is about to jump	They pause or keep their feet on the floor	Attention, pats, or greeting
You ask your dog to drop something	The item leaves their mouth	Food, another toy, a better replacement or the game continuing
Your dog notices a trigger	They look calmly, soften, disengage, show calming signals or check in	Food, distance, sniffing, or moving away
Your dog chooses to settle	They lie down, relax, or stop pestering or barking.	Calm praise, treat, chew, or rest time

Important note 🐾

The marker should happen during the behaviour you want to grow.
So instead of thinking:
❌ “My dog did something good, earlier I will say "Yes” later when I have some treats, 
Think:
✔️ “I will say yes at the exact moment the good choice is happening.” then I can use life rewards or go with my dog to get the treats. 
That is what helps your dog understand which choice earned the reward.

Other Types of Markers

Clickers or other Sound producing devices

A device that produces a sound, usually when pressed.

Benifits

It's a consistent sound. that can carry over long distances. 
It is clear and precise. 
It can be conditioned and used by different people, making it an excellent tool for multiple individuals working with the same dog. 

Limitations

A clicker requires the user to learn how to use one properly. 
The clicker requires one hand to be free. 
Multiple clickers in a group setting can become confusing and distracting. 

To pair the marker effectively with reinforcement, we use  Classical Conditioning. 

For it to be effective, the dog must experience the marker first, followed quickly by a primary reinforcer like food. If the time between the two is too great, then learning will not occur.
If you show the dog the food first, the sight of food becomes the visual cue or lure for the behaviour, making the marker less effective. 
If you use the marker after giving the dog the reinforcement, it is called backward conditioning, and some studies suggest it can weaken the marker. 

Steps for a Good/hold – (Low energy Continuous marker that marks ongoing good behaviour) 

Say the marker word Good, hold or even a Shush sound in a slow, low-energy, calming tone. 
Reinforce with food or gently pat the dog (if they enjoy it), make these actions slow, lingering and deliberate.
Repeat the marker and reinforce again if the dog is in the same position.  
While training, when the dog is performing the desired behaviour, Mark & reinforce, then keep repeating the marking/reinforcement cycle as long as the dog holds the behaviour.

No reward markers (NRM)

No reward markers serve as a form of feedback, letting your dog know they are not on the right track and need to try again. 
When used correctly with the right learner, they can speed up learning and create a better understanding for your dog of what they need to do. 

Some trainers who have built a high rate of reinforcement find blank one or two second pauses more effective than an NRM. Such pauses also encourage the dog to problem solve for themselves. 

If you ask the dog for a well-known alternative behaviour after using an NRM, giving them a chance to still earn reinforcement, it can help to keep them engaged, which is helpful for dogs who get frustrated easily. 

NRM markers should never be used as a punishment and should not have an emotional attachment. If you find yourself getting angry and frustrated, stop using your NRM, and take a break. 

If your NRM is not working as intended, reduce criteria and go back to training the behaviour. 

Using less aversive words like "Uh Oh," "Whops," or "Nice try" can help humans remember to remove the emotion from this marker. 

Before using a no-reward marker, make sure the dog has been trained and understands the behaviour you're asking for and that you are using the right reinforcement when asking for the behaviour.
