I was curios if anyone knew the general extent of a trained dogs ability to detect marijuana?

im curious too. i have a small. glass, air tight, chemical storage grade container that i keep some green in when im in my car. i was curious about if that was all i had on me, if a drug dog could smell anything. just curious. . .

Without going into the very technical end of it, the dogs sense are EXTREMELY strong.

The dog I currently work with smells contact transfer a day or two afterwards. This means he can smell it in a car, when it was in someones pocket a day or two later.

To answer your specific question about smelling in a container, it doesn't matter how airtight it is if there is contact on the outside. As an experiment, we put a gun in a bag containing pot for 20-30 minutes. Then we took it out, hid it and brought the dog in 15 minutes later. He immediately found the gun that had been in contact with the pot. We know metal doesn't absorb odor as well as many other materials, so the result was a little surprising.

Where this applies to you is that if the pot comes in contact with the outside, or with your hands that then contact the outside, it is possible for the dog to smell the odor of mj and lead the handler to your stash.

I really don't know, but my friend got pulled over about a week ago and had some and he had just stopped by burger king and he stuffed his bag in his soda cup... They asked him if they could search the car (don't know why he said yes but whatever ) He got out left the cup in there and the dog just ignored it... either a stupid dog or BK puts something in there soda lol

Did you witness that or were you just getting that information second hand?

I was avoiding this thread because the answer is easily found in a search, and I recommend K9Copper's posts. But I have something to offer here.

Dogs smell at levels so very different than humans that we have a hard time comprehending it. Their sense of smell is measured in parts-per-billion. A part-per-billion would be one foot in 190 miles. Added to that are some specific receptors that measure scents at a molecular level, sort of like a puzzle piece fitting into the correctly shaped hole. The best description I can think of is that dog's smell in layers. If you hide your weed in coffee, a dog will smell coffee and weed. We humans smell the strongest smell, dogs smell it all.

Humans have a huge capacity for olfactory fatigue - making smells go away mentally - after a while we don't smell that stinky hippie sitting next to us anymore, or that joint we just smoked in the car. Because of this we think you can "cover" a smell, relying on our olfactory fatigue experience, humans have fantasies of hiding the MJ scent under various other odors. Dog's don't have this olfactory fatigue problem and therefore you cannot cover the smell of weed - even with that crap Axe that is often mentioned. Dogs do have a working limit - usually considered 30 minutes - when their attention span wanes and they need a break.

How do I know all this? I taught my own dog to search for MJ and it was easy. We called it "find the toy". For the record, my dog never injested MJ and I would NEVER get a dog high. But I had a small baggie sewn into a piece of firehose that I would hide in a number of scenarios - my dog Fang would always find it. Inside the coffee can, in the shampoo bottle, in the stinky outhouse, Fang would find the toy and win a Milkbone.

So why didn't the dog find the weed in the soda cup. Dumb luck.

Poochie-budz suggests bringing a sample directly to our home so he can test how sensitive his nose is.

My brother was telling me about one time he was pulled over with some weed on him. They had about an 8th in an M&M mini's container. When they were pulled over, they stuffed the container with the weed under a blanket which was his buddies dog's blanket. Basicly the blanket that his female dog ALWAYS sits on when they go places, and he takes his dog EVERYWHERE.

They call in the drug dog and I guess all the dog did was smell the **** out of the blanket (being a male, it smelt the female scent I guess) and wondered around the car, didn't find ****. All they had to do was lift the blanket up and there's the weed, but they didn't, and they all went home with no charges.

"So a buddy told me about his brother who read on the internet about a guy who hid his weed in . . . and the dog didn't find it."

We call that anecdotal evidence, and it is not reliable. The dog may have missed your brother's weed but it could have been a number of factors, none of which was the blanket. Dogs do not smell like we humans do, so to apply our experience to their ability is not appropriate. You cannot hide, cover, or overwhelm the sense of smell for a dog; to suggest that you can is a disservice to others here who might try it and get busted. With all due respect, my friend, you brother had some dumb luck that is no indication of the efficacy of dogs.

Sinus infections, mouth infections, and doggy breath issues are sometimes an explaination - but hiding it under another dogs blanket is not stopping the mutt from smelling the weed. He smells the female dog and the MJ.
