there skin if a huge factor the ears bring the sent to the nose the spit makes the scent more extreme and the face skin covers the eyes so the other senses are better
no, but they do have a very good sense of smell
bloodhounds can be used as hunting dogs
Drug dogs in other words dogs used to sniff out drugs can be many breeds of dog. Drug dogs are often dogs with very good sense of smell. Most commonly a German Shepard, however, many other breeds can participate in "drug sniffing". For example Bloodhounds or Labs are sometimes used in airports. Also Bloodhounds can be used on a paralegal case simply because these dogs can sniff out trails hours after they were left. There are also breeds of dogs which can sniff out mold in walls and such. I hope this answer helps it's viewers!
Specialists are almost unanimous that Bloodhounds have the best sense of smell. The second would be Basset hound and Dachshund.
I can't say. All dogs have a very good sense of smell, big or small. Springer Spaniels (Small to medium sized dogs) and Bloodhounds (Large dogs) both have a good sense of smell.
because they have 2oo MILLION smelly receptors. that's 25 times more then we do. the bigger their snout the more smell receptors they have. that's why dogs like beagles and bloodhounds are tracking dogs.
Other dogs butts
Depends on the breed. Some breeds were designed to smell and they are the best at it. All dogs smell several THOUSAND times better than a human. Bloodhounds can smell scents in the air so even a person they are tracking hops a bus,they can find him several miles down the road. German shepherds,labs,and such are used as drug dogs as they can find the tiniest hint of a drug amongst thousands of other smells. There are now even cancer detecting dogs that can find a cancer deep in your body . So I guess there is almost no limit to how far a dog can smell.
Many, many different types of dogs can be trained to become drug searchers. Usually dogs with an exceptional sense of smell are used, such as Labradors, bloodhounds, and beagles. These dogs go through an intense training program and have to pass an exit exam to actually work in the fields as a drug dog.
Maybe it was harder for dogs (bloodhounds) to track them in the rain.
Bloodhounds were primarily used for their strong sense of smell. Since these slaves escaped from their plantations an downers to track the slaves and bring them back to a plantation the overseer or boss of the slaves would usually use their bloodhound dogs to track the escaped slaves. They did this because the process of capturing slaves would be gradually easier with the dogs because their key sense of the smelling of everything in their surroundings to everything in far distances, of course it would get weak and very poor when the bloodhound got near water. But, overall they were used in the process of tracking escaped slaves because their strong sense of smell.
No, dogs smell with their noses.
It is a natural dog behavior to smell "that area" on other dogs and people, because this is how dogs gain information about the person/dog that they're smelling. Much like people get to know other people by what their faces look like, dogs tell people (and other dogs) apart by their smell, and the part of the body where that individual smell is strongest is, well, the groin/rear. So, it is just how the dog tells you apart from other people.
