Dogs have an amazing sense of smell that is far beyond our own.
They can use their noses to detect things we can’t even see, and they can do it from great distances.
This makes them perfect candidates for scent-based search and rescue operations.
But how far away can dogs smell their owners? And what factors influence how well they can smell them?
Perhaps unbelievably, Dogs can detect their owner’s scent from as far away as 20 kilometres when the wind, weather and scenting conditions are suitable.
According to a study conducted by the University of Adelaide dogs have been known to pick up scents of objects and of their owners from as far away as 20 Km when the conditions are right.
Superb sense of smell
Dogs have an incredible sense of smell.
This is due to the structure of their nose, which contains many more scent receptors than our own human noses.
In fact, dogs have about 300 million scent receptors, compared to just 6 million for humans.
This means that dogs can smell things that we would never even be aware of.
And they can do it from far away too.
Just how far away depends on a number of factors, including the dog’s breed, the wind direction and the strength of the scent.
Which dogs have the best sense of smell?
All dogs have a keen sense of smell, but some breeds are more gifted in this area than others.
Some of the best smelling dog breeds include bloodhounds, beagles, basset hounds and borzois.
These breeds have been specifically bred for their tracking abilities, and they have noses that are designed for sniffing out scents.
Bloodhounds, for example, have long, droopy ears that help to trap scent particles and bring them closer to the dog’s nose.
Beagles have wide noses that give them a large surface area for smelling, while basset hounds have long, hanging skin that helps to trap scent.
What factors influence a dog’s sense of smell?
There are a number of factors that can influence how well a dog can smell.
The most important factor is the dog’s breed.
As we’ve already mentioned, some dog breeds have been specifically bred for their tracking abilities and have noses that are designed for sniffing out scents.
Other factors that can influence a dog’s sense of smell include the wind direction, the strength of the scent and the dog’s level of excitement.
If the wind is blowing in the right direction, it will help to carry the scent towards the dog.
Likewise, if the scent is strong, it will be easier for the dog to smell.
Also, if the dog is excited or interested in the scent, or the scent is known to the dog, such as the scent of it’s owner, it will be more likely to focus on it and pick up on even faint traces of the scent.
How do dogs use their sense of smell?
Dogs use their sense of smell for a variety of purposes.
The most obvious is probably tracking, where dogs are able to follow a scent trail in order to find someone or something.
Dogs are also used in search and rescue operations, where they can use their sense of smell to find people who are lost or trapped.
Another common use for dogs’ sense of smell is in detection, where they can be trained to sniff out drugs, explosives or even diseases.
Dogs’ sense of smell is so acute that they can even be used to diagnose certain medical conditions, such as cancer.
Can my dog smell me coming home?
Yes, your dog can probably smell you coming home.
Dogs have a very strong sense of smell, and they can pick up on even faint traces of scent.
So, if you’ve been out and about, your dog will be able to smell you when you come home.
What’s more, dogs, like people, have a scent memory – meaning that they remember certain smells.
The difference is that a dog’s scent memory is much more advanced and capable than a human’s.
This means that your dog will not only be able to smell you coming home but he’ll also be able to smell visitors and other people and animals that he knows – even if he hasn’t seen them for years.
Your dog will also be able to tell where you have been and who/what you have been with too.
Dogs have an amazing sense of smell that is far superior to our own.
They can use their sense of smell for a variety of purposes, including tracking, detection and search and rescue.
What’s more, dogs can even remember certain smells, which means that they can tell when you’ve been somewhere or if you’ve been with someone.
So, if you’re ever wondering whether your dog can smell you coming home, the answer is probably yes and from a long distance away too.
