Clicker or marker word: which should you use
Both do the same job. They tell the dog the exact moment it got something right, before the treat arrives.
Without a marker, you reward roughly. The dog sits, you reach for a treat, by the time it arrives the dog has stood up, and you have just paid for standing up. A marker closes that gap.
What a marker actually is
A sound that means one thing and nothing else: that was right, food is coming.
It is not a cue. It does not tell the dog to do anything. It is a camera shutter on the correct moment.
The case for a clicker
- Identical every time. Your voice changes with your mood. The click does not.
- Cuts through. Distinct from ordinary household noise, so it is unmistakable.
- Faster to time precisely. A thumb moves quicker than a word forms.
- Better for shaping, where you reward tiny fragments of a behaviour, one after another.
The case for a marker word
- You always have it. No clicker left on the kitchen table.
- Both hands free for the lead, the treat and the door.
- Works at a distance outdoors, where a click may not carry.
- Less to explain to everyone else in the house.
The honest recommendation
Use both, for different jobs.
The clicker for teaching something brand new indoors, where precision matters and you have a free hand. A marker word for everything else: walks, real life, the moment your dog chooses not to bark at the postman.
If you only want one, pick a marker word. The clicker you never have on you is worth nothing.
Choosing a marker word
Short, sharp, and not a word you say all day. Yes is the most common and the worst choice, because you say it 40 times a day on the phone.
Better: Yep, Nice, Tak, Bing. One syllable, said the same way every time, not shouted.
Say it flat. It is information, not praise. Praise comes after.
Loading the marker, 2 minutes
Before the marker means anything, the dog has to learn that it predicts food. This is called charging or loading it.
- Sit down with 20 small treats. Ask the dog for nothing.
- Click, or say the word. Wait half a second. Give a treat.
- Repeat 20 times, at random intervals so it is not a rhythm.
- Stop. Do it again the next day.
You know it has landed when you mark and the dog's head snaps round to your treat hand. That is the whole foundation, and it takes 2 sessions.
The 4 mistakes
- Marking late. The mark must land on the behaviour, not after it. Sat, mark. Not sat, stood up, mark.
- Marking twice for one behaviour. One mark, one treat. Always.
- Marking and not paying. This is the fastest way to break it. If you mark by accident, pay anyway.
- Using it to get attention. Clicking to call the dog over turns the marker into a cue and destroys the timing information it carried.
When to stop using it
You do not need to mark a behaviour the dog already knows well. Once sit is reliable, you can pay directly.
Keep the marker for new things and for hard things: the first recall away from another dog, the first calm pass of a bin lorry. Those moments are exactly where precise information is worth most.
On phone apps and clicker sounds
A clicker sound played through a phone speaker works, and it is one fewer object to lose. The delay is small enough not to matter for most training. Just make sure the volume is set before you start, and that the phone is not also the thing you check mid-session.
Every guide is in the app, alongside 99 training skills in 3-minute sessions, streaks that freeze instead of reset, and a care calendar. Free, without subscription or paywall.
