About animals



The likelihood of a dog returning home is very low, but it still exists, which is confirmed by cases of dogs crossing hundreds and thousands of kilometers in search of a home. But what helps animals orient themselves?

It is assumed that in some breeds a sense of direction is unusually well developed, the ability to orientate depends on the intelligence and development of the scent. Many are inclined to the fact that dogs in search of the way home use several methods of navigation at once. But which one is reliable, no one knows. Dog navigation is still a mystery.

Developed sense of smell

Mostly animals rely on the scent, they can follow for several kilometers by a familiar smell. Once in one place, the dog recognizes a familiar smell, and when its concentration decreases, the animal clings to another familiar smell, recognizing it in the interweaving of numerous smells at a specific point, and so it finds the way home through the chain. The sense of smell in dogs is 40 times better than in humans. It is believed that one third of the canine brain is devoted to the interpretation of aroma data, so animals can follow a certain smell, ignoring everyone else. Smells are felt well in cool weather, in the absence of wind, as well as in wet areas with dense vegetation. But odors are not constant, weather conditions and time affect the presence of odor molecules in the air. Therefore, animals must use other methods of orientation.

Mental cards

Dogs are good at creating mental maps, thanks to which they can navigate in space and time. A mental map, combined with a sense of smell, helps animals get home regardless of distance. A pet living in urban conditions is able to remember the route to the house after several walks. In drawing up the mental map, animals rely mainly on their sense of smell and vision. Dogs are able to return home, guided by a mental map, but finding the shortest path through yards and streets, where you had never been before. If necessary, pets are able to memorize large areas.

Animals are believed to rely on a spatial map using memories of familiar smells and visual landmarks. But this theory does not work in cases where dogs return home using unfamiliar routes and traveling hundreds of kilometers.

Earth's magnetic field

Some scientists explain the cases of happy dogs returning home as magnetic attraction. Recent research by scientists has confirmed the perception and use of the Earth's magnetic field by many animal species for orientation and navigation. Dogs and some primates can sense the Earth’s magnetic field with cryptochrome in their eyes. Cryptochroms are photosensitive molecules that are present in bacteria, plants, and animals. Cryptohorms in animals are involved in the regulation of circadian rhythms of the body - cyclic changes in biological processes associated with the change of day and night. Due to the ability to perceive the Earth's magnetic field, four-legged pets use it as an orientation mechanism - a pocket compass, although the ability to perceive the magnetic field in dogs is expressed in a weak form, unlike birds.

Strong connection with the owner

An important factor is attachment to the owner. Lost animals dependent and attached to the owner will look for ways to return and reunite with him. There are cases when shelter dogs and pets transferred to other owners ran away from the new house back to the shelter or to the previous owner, even if they were in another settlement. But exactly how animals do this does not lend itself to logical explanation, although numerous experiments were carried out in this direction that did not give answers to the questions posed.

Amazing cases of dogs returning home

The case of the happy return of the dog occurred in 1979. The owner brought the Metis Labrador and the boxer to the farm. Jimpa was supposed to be helping on the farm, but the mestizo, having covered about 3200 km, returned to his old house in Pimpinio in Victoria, Western Australia. The journey took 14 months.

In 2013, Alexander Petrov, who came to Astrakhan on vacation, lost his dog at the railway station. At that time, Sam was only 6 months old. The owner suggested that there was no way for the dog to move, so when he got down on the platform, Sam, full of energy and curiosity, ran away. Catching Sam failed, he was searched for two weeks. The search yielded no results, the vacation was coming to an end, and the owner had no choice but to return home to Perm. Alexander despaired of ever seeing his pet, but after 4 months he came across an ad about a found dog posted on a social network. The dog pictured in the photograph looked like Sam. Even more astonishing was the information about the whereabouts of the dog, which was found by volunteers at the train station in Perm. Sam covered the distance of 1.5 thousand kilometers on the sleepers. At the meeting, the dog recognized the owner, no one doubted that it was Sam.

An accident occurred in Connecticut, a two-year-old Airedale terrier named Max jumped out of a crumpled car and ran into the forest. Owner Bill Clark, not finding him in the forest, returned home to Coventry, Rhode Island, where he organized a search campaign that lasted two weeks. Ineffective searches reduced the chances of the dog returning home. But one day, Bill Clark returned home and found in the backyard a contented Max who independently found his way home, having covered 72 km of track. Max's amazing journey took place in an area inhabited by many predatory animals. After examination by a veterinarian, it turned out that Max had no serious injuries, but during the month of his journey he significantly lost weight.

Black Labrador Bucky owner Mark Wessels, who lived in South Carolina, was forced to leave his father in Virginia. But Bucky escaped and, having overcome 800 km, returned to Mark independently, having found a temporary refuge with friendly people on the way. There was no news of the dog for several months, the owner had already begun to lose hope that he would see his dog again. There was a strong connection between Bucky and the owner, they were best friends. Perhaps it was this connection that helped the dog find his way home. Bucky reached the resort town of Myrtle Beach (South Carolina) and ended up in a veterinary clinic where they found a microchip. The dog first heard his name and reacted joyfully to it, and soon Bucky reunited with the owner.

Another story about the reunion of the dog with the owner is so surprising that it is difficult to believe in it. An Irish terrier named Prince set off in search of his owner, who left as a soldier to serve in the British Army during World War I. The dog missed his master, he lost his appetite and looked depressed. As a result, he could not stand the breakup and ran away from home. It remains a mystery how the Prince managed to cross the English Channel, but he ended up on the territory of France and found his owner in the trenches at the scene of the fighting, not afraid of the whistling of bullets and bombings.

A miracle dog named Bobby was absent for six months. In 1923, a mestizo of an English shepherd and a Scottish collie was lost while traveling in Indiana. It was not possible to find the animal, and the owners decided to continue on without Bobby. Six months later, a depleted Bobby with his paws worn out came to the door of his master’s house in Silverton, Oregon. He covered 4105 km through deserts, plains and mountains in winter. During the day, Bobby walked about 23 km. Upon returning home, the dog experienced a rapid rise to fame, they wrote about it in the newspapers, and in 1924 Bobby played himself in the silent movie “Call of the West”. Unfortunately, the dog lived only 6 years, but they still remember about it. Not a single monument has been erected in his honor and annual parades are held.

I’m just writing down this whole whole in the "baby face", relatively speaking. The absence of sexual demorphism should be directly related to the hormonal background.

I think that dogs as well as people have different deviations.

But what Wikipedia writes about this

There are a number of scientific papers showing that homosexual behavior occurs not only in humans, but in many animals. In 1999, Canadian researcher Bruce Badmill described homosexual behavior in more than 1,500 species and is well documented for 500 of them. A review of existing studies in 2009 showed that homosexual behavior is an almost universal phenomenon in the animal world, common to all species.
At the same time, the phenomenon of homosexual behavior in animals is multifaceted even within the limits of one species: it can have a social character, substitute, can be an independent analogue of heterosexual behavior or an artifact.
Some scholars believe that in some cases, homosexual behavior in animals is an evolutionary tactic of behavior that increases the chances of survival of the species.
LGBT activists use scientific studies of homosexual behavior in animals as an argument in a discussion about the physiological and social normality of human homosexuality, against the assertion that homosexuality is a "sin against nature." This argument was made in the US Supreme Court in Lawrence v. Texas, a decision in 2003 that completely decriminalized homosexual relationships in the United States.
