Dogs get used to their human's smell

New research out - 'Discrimination of person odor by owned domestic dogs' Discrimination of person odor by owned domestic dogs

Hopefully accessible, the abstract is below:
In the field of dog cognition research, many studies assume that their subjects have multimodal recognition of their owner: Experiments using the face or voice of the person have proliferated. An outstanding question is whether owned domestic dogs represent the people with whom they live via smell. Olfaction is a principle sensory modality for dogs, and there is evidence that it is integral to recognition of conspecifics. In the current study, we investigated whether owned dogs spontaneously (without training) distinguished their owner's odor from a stranger's odor. Using natural body odor captured on a t-shirt, we found that dogs habituated to a familiar odor and dishabituated to an unfamiliar odor. This finding begins to answer the question of how dogs recognize and represent humans, including their owners.

I can go with this , Nelly is deaf, her eyesight is also not good . I watched her on the beach today, she had been having her very own little zoomie and strayed out of her eyesight range , I observed her scenting the air , then running towards me so yes , scent plays a massive part of recognition x
