Scientists have observed tiny smoke particles moved by unseen particles in a rapid, irregular fashion
Yes. What you smell is gaseous (or vapor) particles of matter.
Smells are actually particles that are airborne. The reason you can smell things from other rooms for example is because of the air curculation and movement in your house (hot air rises) which is carrying small particles, which you inhale through your nose.
When particles heat up they gain energy and move faster. When a smell is added these faster moving particles spread the smell faster than if they were cold (with less energy)

Particles sloughed or emitted from the body would be released into the ambient air. Because of Brownian motion, these particles would be diffused into the local environment along a gradient being densest near the source (your body). The dog's nose would interpret the greater density of particles as a stronger smell and thus by following the smell to where it is strongest, find the source.
