It is well known that dogs are real super noses. Not for nothing one holds out his hands to a friendly appearing dog to greet him so that he can sniff at him and decide if he likes us or if he prefers to stay at a distance.
But which ultra-fine antennas the sense of smell of fur-noses actually possesses, is researched more and more in the last decades. The results exceed even the boldest expectations – now all the dog owners who always reported on the foreboding of their four-legged friends have finally confirmed: Yes, dogs really know many things earlier than humans because their nose has already betrayed them.
Dogs can also perceive the slightest changes in the body odour of “their” humans. During pregnancy there are drastic hormonal changes in the body and a dog will notice early on that something is different than usual. Perhaps he will also be disturbed at first, because his human being suddenly smells like someone completely new.
Dogs recognize others less by their appearance than by their very own, typical smell. If you disguise yourself artistically, you can deceive other people, but a dog will only be a little confused until he is close enough to identify you by your smell. Then there is no more doubt – even wigs and false noses won’t help. Well-trained dogs can even tell identical twins apart by their smells.
Cancer changes the way our cells work, causing cells to proliferate uncontrollably and tumors to grow. The diseased cells produce a special protein that can be stormed by dogs. Research has shown that this is not a myth: dogs can sniff lung cancer on their breath and bladder and prostate cancer on their urine.
4.) Epileptic seizures
Dogs can anticipate an epileptic seizure in humans up to 45 minutes before its onset. It is assumed that the actual seizure is preceded by a very specific change in body odour. Dogs often start barking upset and can warn their humans.
5.) Interactions with other dogs
A well-known situation: One has stroked another dog on the way and when coming home one’s own four-legged friend does not want to stop sniffing out his humans with interest. What’s he hearing? For example, which breed, which sex and which mood the other dog had. I’ll be damned!
6.) Changes in blood sugar levels
Studies have confirmed that dogs can smell it when our blood sugar level is low – our sweat smells different. For dog owners suffering from diabetes, it can be a valuable warning signal when their coat nose reacts nervously to the changes.
7.) Storms and storms
When animals suddenly seek safe shelter for no apparent reason, humans do well to follow their example – something is literally “in the air”. Dogs can sense the slightest changes in the air and are also very sensitive to ground vibrations. When the dog suddenly flees, let’s go after him.
It’s hard to believe what dogs perceive through their fine noses, which we humans don’t notice at all. We are well advised to pay attention to their behavior and take their warning bark seriously – it could one day save our lives.
