🐾 SCENTWORK TRAINING - THE LOOK BACK OR THE WOODPECKER! 🐾
Does your dog find the target odour and immediately look back at you? Or perhaps they do a little ‘woodpecker’, moving their nose back and forth between the source and you?
It is something I see quite regularly in scentwork training, and there can be several reasons why it happens.
So, why might this be happening, and what can we do about it?
Here are my TOP SIX things to consider when troubleshooting this behaviour. 🔎🐕
1️⃣ IS YOUR DOG UNSURE THEY ARE CORRECT?
Sometimes that little look back is a dog seeking information or reassurance from their handler. They have encountered the target odour, but perhaps they are not entirely clear about what is expected of them or how to earn their reinforcement.
This is where I would revisit the foundations. Go back to some simple, familiar exercises and build more value for the target odour. Revisit your odour imprinting, strengthen the association between finding the odour and receiving reinforcement, and give your dog plenty of opportunities to be successful.
Don’t be afraid to go back to basics. Sometimes that’s exactly where the greatest progress is made.
2️⃣ ARE YOU MARKING THE LOOK BACK RATHER THAN THE NOSE AT SOURCE?
This is a really common one.
Your dog reaches the source, their nose is there for a split second, they turn towards you and then you say your marker word.
What have you actually marked?
Potentially, the look back rather than the behaviour you wanted.
If you know your dog has a tendency to glance back, anticipate it. On a known hide placement, be ready to mark the moment their nose reaches source, before they turn towards you.
Initially, don’t worry about building a lengthy duration on their nose holding (freeze). Capture that lovely moment of recognition and reinforce it. Duration can be developed later, once your dog has a clearer understanding of the behaviour.
This is also where working with an instructor can be so valuable. They may be able to advise when your dog is approaching source or even mark the behaviour for you, allowing you to observe pre signals and concentrate on delivering the reinforcement.
3️⃣ IS YOUR REWARD GIVING THE GAME AWAY?
The rustle of the coat, the treat pouch being opened , the hand creeping towards the pocket or any tiny movement we don’t even realise we are making
Our dogs are incredibly observant, and they can become very good at recognising the little signals that tell them their reward is coming.
Sometimes the dog has not looked back because they are unsure about the odour at all. They have simply heard or seen something that predicts their reinforcement.
Watch yourself on video. Are you reaching towards your reward before you have marked? Are you preparing to deliver it as your dog approaches and lands at source? I have done this, we want to deliver efficiently, it’s so easy to be that split second too early.
Try keeping your hands still, when working off line, I try to pin mine behind my back out of mischief, reward out of sight and your body language neutral until you have marked the behaviour.
4️⃣ MARK FIRST, THEN MOVE TO REWARD
This follows from number three
We can inadvertently teach our dogs that our hand moving towards the treat pouch is the signal that their job is finished, rather than the marker word itself.
Your marker should identify the behaviour you want to reinforce. Once you have marked, then move to retrieve and deliver the reward.
Mark the behaviour first. Move second. Reward third.
It sounds simple, but those little fractions of a second can make a difference.
If you are working towards a longer nose hold duration at source, you need to be clear about exactly which moment you are marking. Be consistent with progression.
5️⃣ ARE YOU ALWAYS MOVING FORWARD TO REWARD AT SOURCE?
In the early stages of scentwork training, we often move towards our dog to deliver reinforcement directly at the source. This can be really useful to encourage the dog to remain close to source and for building value for the target odour.
However, over time, some dogs begin to anticipate our movement or become very aware of where we are in relation to the reward.
If appropriate for your dog’s stage of learning, try varying your reward delivery.
Mark the correct behaviour and then toss the food or toy close to the hide placement, rather than always stepping forward to deliver it directly.
This can help separate your movement from the behaviour you’re marking, whilst keeping reinforcement associated with the source area. If your dog is super sensitive to your movement, once again having another person deliver the reward after the marker can start to break the cycle
6️⃣Pairing
Some training methods pair the odour and food together from foundation and for quite some time in the dogs progression. The food is accessible for the dog. This is to build value for the target odour and motivation. Nothing wrong with this for those aspects above, but once the food is removed the dog immediately looks back as if to say ‘uh, where is it ?’ This is then marked as the dogs indication. Over time though they can look back for other reasons and the handler is then unsure, observation skills of pre signals have to be acute here.
Unless troubleshooting a lack of motivation, I would initially build value for the odour with more simple searches, quick firing the rewards down to the dog when they offer nose hold Indication, so quick the head stays down and doesn’t look back. Running alongside this indication duration training on one item. Taking your body cues out of it by sitting on the floor and building duration. Then add a choice of two items, gradually building up. Both of these methods will build value for the odour, dropping of the pairing in searches sooner.
⭐️Key Pointer Reward delivery and marker timing are two different things. It’s the marker that identifies the precise behaviour being reinforced. If you want to build duration at source, gradually develop that nose hold before marking, but cross that first hurdle of the ‘woodpecker’ behaviour first.
🐾 A FINAL THOUGHT…
These are just six of the things I would look at when troubleshooting a dog who regularly looks back or ‘woodpeckers’ between source and handler.
There can, of course be other reasons. Your dog may lack confidence in the environment, be uncertain about the task in front of them, or have developed a particular indication behaviour through their previous learning history.
If this is a problem for you consider what behaviour you are actually training, what your dog understands and what is happening in that particular moment.
Sometimes just a tiny adjustment in our marker timing, movement or reinforcement can make a significant difference.
And if you are unsure, video your searches. You may be surprised at what you discover when you watch them back.
❓Does your dog have a tendency to look back at you when they find source, or do a little woodpecker between you and the hide? Have you discovered what might be contributing to it?
