Dogs are different from humans in the fact that when we smell we don't smell individual things. When you have a stew all mixed together we smell stew. Dogs smell everything that is in the stew individually ( carrots, celery, beef). The other factor is how smells permeate. If you have your stash of weed freshly packed in a ziploc bag you can't smell anything, keep your weed in there and wait an hour and smell your bag. Smells like weed now. What most people don't get is that when trying to cover up the smell of weed with something like cayenne pepper or coffee the dog smells first the cayenne pepper/ coffee and then smells the container and then the weed. The best way to avoid this is when transporting weed don't put it in a container days before transporting. Put your weed in something like an empty coffee tin right before you leave. The dog will then smell the container and then the coffee possibly and not the weed.
Don't use anything strong to cover up the smell of weed like pepper because the dog with having a sensitive nose will jerk it's head and the K-9 officer is looking for that. The most effective way to avoid being caught is having a kitten/ cat in the car with you. Dogs can not do their job when a cat is around. Also around roadkill dogs can not find anything.
There was a bust this cop made where the dog smelled weed that was put into pvc pipes and stored in the gas tank with gas. Due to how long the weed was in there it permeated. The dog smelled individually the car, gas tank, gas, pvc, and then the marijuana.
I hope you guys can appreciate this.
