The Reason Behind Dogs Smelling Each Other

Dogs smell each other as both a form of communication, but also to learn more about the other individual. A dog’s sense of smell is much more advanced than ours, this means their sense of smell is a tool to transfer and receive information from another dog. Compared to us, their sense of smell is 30 times better than ours. Olfactory receptors are the parts that allow us to receive information about smells, the more we have the more advanced our senses. Humans have around 5 million whereas dogs have around 150 million.

Furthermore, dogs have a Jacobson’s organ, something we do not. This little organ exists in the nasal cavity to help your dogs to communicate specifically through chemicals. The way that this organ is different from your dog sniffing to detect smells is what it can actually pick up. It has been found that this organ is able to detect smells that the nose cannot which may be those that are left deliberately for communication. It is most well adapted for instinct-driven behavior such as mating, motherhood, and general hormonal responses. From the moment a newborn puppy is born they can use this sense to seek out their mother’s milk. This organ is also suspected to help identify family members, even after a number of years have passed, therefore there is a suspected link to memory as well.

What Does It Mean When Dogs Smell Each Other

The forms of communication that two dogs use through scents are extraordinary. In the manner you or I would discuss traits, interests, and defining features, a dog can assess in mere seconds through scent. They can quickly identify the gender of the dog, and if there would be any prospective mating in the future. They can also understand the dog’s health. Although the depths of this point are not yet entirely understood, it is believed a dog can see injury and illness. This is why dogs are so using to detecting oncoming seizures, sugars dropping in diabetics, and other health issues in humans.

This isn’t all though! A dog can also identify the mood of the other dog immediately, arguably why they can be so empathetic. However, it can also be a very useful tool to help keep them safe. If a dog is upset, angry, or scared, these moods could all result in a potential bite. Therefore, they may try to avoid dogs that appear to be in a negative mood. Similarly, if they are ill, they may be more reactive. some question whether a dog would be more gentle around others if they are ill out of concern, self-preservation, or a little of both.

Sniffing the anal glands in the dog’s butt can also provide a lot of information. Allowing another dog to sniff them to obtain this information is a friendly welcome, whereas sitting down may be a form of protection or signify wariness.

Is It Safe To Let My Dog Smell Others

This is a perfectly normal behavior in dogs, so in this sense, it is safe. However, there are some safety concerns you should be aware of. These may include your dog misjudging a situation, those with contagious diseases, and dogs who are not neutered or spayed.

Although dogs have these scent receptors, like with us, they can misjudge situations. They may detect an adrenaline increase but attribute this to excitement as opposed to anxiety. They then could run-up to a nervous dog to sniff them, and the other dog may bite them. Furthermore, sniffing is not the only sense that dogs use to judge another. They will use their sight as well to see if a dog appears happy. Those that are unsocialized may not understand aggressive or anxious behavior. Therefore, they may go up to sniff another dog and misjudge that dog’s behavior. It may also be that the other dog has difficultly judging features, such as long, black fur covering the face. This makes the features difficult to discern.

Whenever you take your dog out for a walk, it is important that they are properly vaccinated. Those that are not could catch many contagious diseases which can have severe consequences. Even those that are vaccinated may be at a slim risk of contracting parasites, such as fleas and worming. Be sure to keep your dog up to date on their worming and flea treatment. Lastly, if your dog is in season, or is a male who meets a female in season, there could be a risk of pregnancy. When your dog smells the pheromones then they may react, and this can be especially concerning in very young individuals or females that are not well.
