The sound of rain annoys dogs

While listening to the sound of rain is meditative for humans, dogs are not doing so well. They find the sound of rain extremely unpleasant for their sensitive hearing. So make your dog happy and let him in when it rains. It would then like to crawl into a quiet corner.

Dogs hear much higher pitched sounds than humans

Another interesting ability is hearing high-pitched sounds. We take advantage of this with the dog whistle, which mostly whistles above our human audible range. Because our four-legged friends hear up to 50,000 Hz. Nothing happens in the human ear anymore. Keep this in mind when a dog hears any sound that no one else can hear. Maybe it's in that tonal range.

Scientists have found from thousands of observations that dogs lighten in a north-south direction. It doesn't matter whether it's the bladder or the intestines. The only thing that matters is whether the dog is on a leash. Because then he can usually not live out his natural instinct arbitrarily. Our four-legged friends use the earth's magnetic field for orientation, just as has already been observed with birds or cows.

The muzzle is the dog's fingerprint

It is still fascinating for us humans that really every human being has a unique fingerprint. Even identical twins have different prints, albeit very similar. The same applies to the nose impression of the dog. Every dog ​​has a unique nose print. If we introduce dog passports one day, we need to store the noseprint there.

Dogs can smell cancer or diabetes

The sense of smell of our beloved four-legged friends is so sensitive and fine that they can even smell our illnesses. The sense of smell is about 10,000 times stronger than the human one because our furry friends have up to 300 million olfactory cells. Therefore, trained assistance dogs can even sniff out dangerous sugar levels in diabetics or impending epileptic seizures. They also actually smell cancer cells, which is already being used by medical professionals. But the police also let the four-legged friends sniff out drugs and explosives as well as hidden people, which is also used in earthquakes or avalanches.
