Air scenting is one of the ways that dogs can gather information from their environment, but why do they choose to do it, and what can it tell us?
Has your dog ever stopped on walk and held their nose high in the air, their nostrils twitching? If so, you've watched them air scenting. Sampling odours in their environment and processing it, before taking action. This may be to chase, hunt, or maybe even get some distance from the scent. In scentwork, their behaviour can tell us A LOT.
No two dogs will work the same, and they can adapt the way they search according to the information available to them and the environment they're working in. Jinn, Connor and Jacobs (2020), for example, found that environmental conditions influenced dogs' search behaviour while following trails, including how closely they searched in relation to the trail.
Temperature, humidity, wind, terrain and the movement of air can all influence where odour is available. So when we watch a dog lift their head, change direction or suddenly put their nose back to the ground, we may be watching them solve a constantly changing scent problem.
Understanding how dogs search, rather than simply whether they find the target odour, is one of the things that makes the science of scentwork so fascinating.
If the science behind scentwork interests you, you can study with The College of Scent Dogs from home too.
Our Learn Online for £99 programme gives you access to hours of teaching from Dr Robert Hewings, based on the award-winning book 'Scent Training for Every Dog'.
You'll explore the theory behind scent detection alongside practical training videos and guidance to help you begin your own scent detection journey with your dog.
