So after the scent work trials at West Eryton which was a rural school surrounded by large pine trees . I noticed when my dog brushed past some pine foliage a huge puff of tree pollen blew up . That got me thinking as a lot of very good teams where not succeeding in their searches. I was quite surprised by this and got me thinking !?!?!?!??!!
On the sat Ariel would not commit to source on the vehicles but got all the odours which is most unlike her . On the sun in an inside search she was her normal self .
So I concluded we were all searching in a big pollen laden environment ! So after some research !!!! Yes it is proven that
Heavy airborne pollen can temporarily interfere with a dog’s scenting performance in a few ways: it can irritate the nasal passages, increase sneezing or nasal secretions, and create a very “busy” odour environment. If you were literally seeing clouds of pine pollen when branches were disturbed, the dogs were working in a substantial load of airborne particulate matter.
That doesn’t mean the target odour disappears, but it may make scent acquisition less clean. You could see dogs taking longer to commit, appearing less decisive, repeatedly checking areas, working unusually high or low, breaking off odour, or simply seeming “not quite themselves.” Some dogs may be affected considerably more than others.
There’s also a second factor: pollen conditions often coincide with changing spring weather, temperature shifts, humidity and wind movement. Those can alter how the target odour plume moves through a wooded site. So you may have had both an environmental scent-dispersion problem and a physiological nasal-irritation problem happening together.
The thing that particularly interesting I observed is that multiple normally competent dogs seemed off at the same venue and time. When that happens, I’d be much more inclined to investigate the environment rather than immediately conclude it was a widespread training issue.
