The reason trained dogs can sniff out electronics is because of a chemical in the manufacturing process to prevent overheating. Triphenylphosphine oxide (TPO) has a scent. Larry is always training, finding things in the snow, rain and under water.
The dogs are able to detect electronics of all shapes and sizes because all electronics have a circuit board. All electronics use a compound called triphenylphosphine oxide (TPPO), which covers the circuit boards in electronics to prevent overheating.
A detection dog or sniffer dog is a dog that is trained to use its senses to detect substances such as explosives, illegal drugs, wildlife scat, currency, blood, and contraband electronics such as illicit mobile phones.
The dogs are trained to indicate on things such as thumb drives, SD cards, microSD cards, anything they can hold or store images that can be used in child sexual abuse materials," says Jordan. He says it's all about harnessing a dog's remarkable sense of smell.
The Peel Regional Police Department in Ontario has enlisted a new officer: an "electronic storage device dog." Harley, a 2-year-old yellow Labrador Retriever, is the first dog in Canada to be trained to sniff out digital storage devices, according to the department.
However, sniffer dogs are not capable of smelling illicit drugs inside the human body. Their training focuses on detecting the odour of drugs in the air or on surfaces. They are not trained to detect drugs that are concealed within the body.
It turns out that memory storage devices like USB drives and micro SD cards are coated with triphenylphosphine oxide, or TPPO, which has a distinctive smell that dogs can be trained to detect.
The short answer is no. Sniffer dogs and your dog at home have impressive abilities, but they can't smell through materials like glass jars.
Yes they can. They can also smell through multiple layers of plastic and they are not fooled by masking scents such as coffee grounds.
Although man's best friend tends to have a pretty incredible ability to sniff things out, dogs cannot smell though airtight, vacuum sealed containers.
The trial, held over a six-month period in Lyon, tasked two dogs with checking large volumes of various cargo types and they found both lithium ion and lithium metal phone batteries with 100% accuracy. In fact, the dogs were able to detect single batteries in the middle of one cubic meter sized shipments.
Opiates. Like opioids, the term "opiates" refers to a class of drugs. These drugs are similar because they come from opiates. One of the most common opiates is morphine, a drug that is legal when prescribed, meaning that police dogs cannot learn to detect it.
Dogs absolutely can see TV, and many seem to enjoy it. There are a number of features about television shows that dogs find attractive. Some of these are visual, such as motion, while others relate to the sounds coming from the TV. Dog eyes are very different from human eyes, so they see things on TV differently.
In other words, they're good at catching the basic, big-picture idea of the object or scene in front of them. But small screens and compressed data mean dogs can't identify faces on phone or tablet screens. If you have a jumbo-sized, high-def television monitor, your dog may be able to recognize you on a Skype call!
To put it simply: “Dogs definitely do not understand FaceTime or phone calls,” says Dr. Nathan Lents, a biology professor at John Jay College. “The issue here is that dogs, like most snouted mammals, navigate their world with their incredible noses.
A detection dog trained to pick up the smell of a specific substance does not need additional training to smell through foil. A trained sniffer dog zeroes in on even the faintest odor, no matter what the object is wrapped in.
For dogs, citrus scents are the enemy. Citrus scents like lemon, lime, oranges, and grapefruit–especially in high concentrations often found in household cleaners or essential oils–can cause irritation to your pup's respiratory tract, so keep any fresh citrus fruits out of your dog's reach. You know–just in case.
Our canine companions have proven once again how finely tuned they are to our feelings - this time in a scientific sniffing test. Scientists discovered that dogs can smell stress in our breath and sweat.
The chemical aromas communicate what a dog likes to eat, and identify gender and mood. By simply smelling, a dog can determine if a new friend is male or female, happy or aggressive, healthy or ill.
An active or aggressive alert occurs when a dog responds with a vocal or otherwise overt reaction to locating drugs. An active alert might be barking, straining toward, digging, or pawing at the spot where the drugs are located.
Dogs have an extremely complex smell ability. Dogs will remember a human days, weeks, months or even YEARS. When a pup combines their ability to remember scents, facial recognition, and voice recognition- even after one meeting- it is quite extensive.
Cayenne Pepper
Most “drug dogs” cannot tolerate even the slightest whiff of cayenne pepper.
Yes, it's true, many dogs are able to smell through walls. Owners of an intact female are probably already aware of this, as any intact male in the area is likely able to tell where their girl is - even if she is inside!
But is it overwhelming enough to hide another weaker scent? The answer is no! Dogs can, indeed, smell through coffee because they build up a scent profile. Much like the top, middle, and bottom notes of a perfume, a dog can distinguish a range of smells, separating them from one, more dominant smell.
