Chaining tricks together: back-chaining
To link several tricks into one smooth sequence, teach the last step first, then work your way back towards the beginning. Each link becomes the cue for the next, and your dog is always running towards what it knows best: that is back-chaining.
Why start at the end
A chain is several already-known behaviours performed one after another on a single cue (go to the toy, pick it up, carry it to the basket, drop it in = "tidy up"). In back-chaining, the last link is over-learned first: it becomes the anchor point. With every link added at the front, your dog moves from the least familiar towards the most familiar, so towards something reassuring. In forward chaining, it moves away from the familiar and the sequence falls apart at the finish.
Before chaining: check your building blocks
A chain only ever reveals how solid each link is. Check every behaviour on its own first.
0 / 4Building the chain, link by link
Always start from the last link and work backwards. The reward migrates towards the end of the chain.
Over-learn the last link
Work it on its own and pay it generously: this is the link that will carry the whole chain. It should become your dog's favourite behaviour, performed straight away and with enthusiasm.
Add the second-to-last link
Ask for the second-to-last link, which leads into the last one, and reward only at the end. The last link now pays for the one before it.
Work back one link at a time
Add each link at the front of the existing sequence. Golden rule: only add a link when the current subset runs without hesitation.
Fade the intermediate rewards
At first you can mark a few links along the way; gradually fade towards a single, generous reward at the end of the chain. The sequence itself becomes reinforcing.
Add the overall cue and generalise
Say your single cue ("tidy up", "routine") just before the first link, let the intermediate cues fade, then run through it again in two or three settings, shortening the chain each time.
A chain is built over weeks, not in one evening. Short, spaced-out sessions help learning (Demant et al., 2011): two or three successful run-throughs beat one session that drags on.
If it drops out halfway through
A dog that stops, vocalises or improvises in the middle of a sequence is not being stubborn: a link that wobbles on its own collapses within a chain. The remedy is always the same: break it down, re-solidify that link on its own, then re-chain. Three failures in a row: shorten the chain and let it succeed. Never any insistence or physical force to "reposition" the dog (AVSAB, 2021).
Three chains to practise with
Tidy up your toys
- Last link learned first: dropping the toy into the basket.
- Picking up the toy is added last.
- A single reward after the drop, never at the pick-up.
Take it to someone
- Handing the object into the person's hand is the over-learned final link.
- Carrying it, then picking the object up, are added as you work back.
- The reward comes from the person reached, never on the way back.
Go to your spot (at a distance)
- The mat is the final link, already positively charged.
- You simply move the starting point back, step by step.
- You pay on the mat, never by calling the dog back to you.

Frequently asked questions
What is back-chaining with a dog?
It's a technique for teaching a sequence of tricks: you teach the last step first, then work back towards the beginning. Because the end is the best known, the dog is always moving towards the familiar, which stabilises the whole chain.
How do I teach my dog to link several tricks together?
First check that each trick holds up on its own, under its own cue. Over-learn the last link, then add the second-to-last one, paying only at the end, and work back one link at a time. Never add a link while the previous one is still shaky.
Why does my dog drop out halfway through a sequence of tricks?
Almost always because a link isn't solid enough on its own: it collapses once it's put into a chain. Break it down, rework that link on its own, then re-chain. Never any insistence or force to "reposition" the dog.
Do I need to reward every trick in the sequence?
At first, yes, you can mark a few links. Then you gradually fade towards a single, generous reward at the end of the chain. That's the one that pays for the whole sequence, and the linking eventually becomes reinforcing in itself.
How long does it take to teach a dog a routine?
Think in weeks, not one evening. Short, spaced-out sessions help learning (Demant et al., 2011). Two or three successful run-throughs per session beat one long session that ends up fraying.
How do I get started with dog dancing (freestyle)?
A choreography is a long chain built up in small modules by back-chaining, then assembled to the music. Work on non-slip ground and limit jumps and twists; nothing acrobatic before growth is finished.
Is it better to teach the first or the last step first?
The last one. That's the whole point of back-chaining: the dog moves from the least familiar towards the most familiar. Starting from the beginning takes it away from the familiar and the end of the sequence unravels, right where back-chaining lays down something solid.
