Did you know that our senses include the perception of the magnetic field? While we have almost lost this ability already, dogs still have it and use it every day. Do you know for what?
Maybe you have noticed that your dog partner sometimes takes quite a while before he finds the right spot to do his needs. And that's just the effect of a magnetic field. Since dogs take up such a position doing so, that their body is directed into a certain direction towards the Earth’s magnetic field.
Sounds unbelievable, right? However, a recent Czech-German scientific study proved, that dogs are sensitive to small changes in the Earth's magnetic field, which in turn affects the way they “go to the toilet”. A team of scientists found out after several years of monitoring of dogs, that if the magnetic field is calm, the dogs prefer to align their body on the axis from the North to the South when doing their needs. However, if the magnetic field becomes unstable, dogs have no directional preference.
Scientists from the Czech Agricultural University and the German University of Duisburg-Essen wrote in the context of publication in the scientific journal Frontiers in Zoology online, that measuring of the direction of the axis of the body was carried out in 70 dogs of 37 breeds during defecation (1 893 observations) and urination (5 582 observations) over a two-year period. Collected data was sorted according to geomagnetic conditions in the individual periods of data collection. Directional preferences of the dogs in various conditions of the magnetic field were then analysed and tested using a circular statistics.
Based on this research, the scientists came to the conclusion that the behaviour of dogs is predictable based on fluctuations in the magnetic field. However, they are not sure why dogs are adapting to it while carrying out their needs. Whether they do it consciously (i.e. if they see or feel the direction of the compass in any way) or subconsciously (whether the direction is controlled on an autonomic level - they only feel better or worse when facing a certain way). The analysis of the collected data only shows that dogs prefer the North-South direction and at the same time they avoid the East-West direction.
This magnetic positioning has been observed also in other mammals besides dogs, for example, in cattle or deer. Foxes plan the hunting trajectory precisely based on the magnetic field. In turn, wolves have extremely large territories. This suggests that they have excellent orientation skills, in which the scientists also see also a link with the perception of the magnetic field.
In any case, based on this discovery, the scientists established, that new horizons have opened up in magneto-biological research.
What do you think about it? Have you noticed that your dog always turns in the same direction when doing his needs? Try to notice it and share your experience!
Although it might appear that the cat doesn’t give a tail about you and it is indifferent towards you, maybe you will still find some displays of affection in its behaviour. Do you know how cats show such affection towards a person?
Cats love grass. They nibble at it if it's to clean their belly from hairs or just for fun. In addition, if you get a cat its own flowerpot, you can hope that it will leave your other plants alone :).
Whether you remove a tick from a dog’s or cat’s fur the right way might affect whether the animal will become infected with Lyme disease or another malign disease transmitted by ticks. Have you got the right technique and tools?
Just like with people, also in dogs, Lyme disease is a very grave illness. There are an estimated 20% of ticks infected in the Czech Republic. And because despite the use of antiparasitic agents, your dog might get a tick from time to time, it’s good...
I’ve already written about cat mint, today, we’ll take a look at another, lesser known drugs. Since not all the cats respond to all of them and they don’t respond to everything the same way. Therefore, if you didn’t succeed with cat mint, maybe you’ll...
Every cat owner has certainly already heard of cat mint, catnip or catswort. Under all these names hides a herb that makes most of the cats “high”.
When your family grows by a new (human) member, it isn’t necessarily a happy event for everyone. For many dogs, it’s very difficult to come to terms with such situation, therefore, it’s better to start preparing them already before the baby is born....
I’ve already written about the fact that you’re not supposed to leave your dog closed in a car on summer days or on how to prevent hyperthermia in cats and dogs. So you have mastered the prevention already. But it is also necessary to know how to...
Without a question, chinchillas are beautiful and cute furry animals with large ears, a long tail and distinctive eyes. Do you know where they actually come from, what their name means and that we almost succeeded in nearly exterminating them before...
You have probably noticed that cat tongues are quite unique. They are rough and somehow scratchy. It seemed weird to American biologists and therefore they decided to look deeper into it.
What should I say, the cats are simply different. Since the time immemorial, they have been surrounded by mysteries and secrets. Most of them behave as if they were the master of the world and as if they don’t need the human at all. A couple of...
It can be quite a task to choose the right pet food precisely for your cat. To even understand the contents... That’s why we’re going to take a look today what to focus on, what to look for in the contents and what you should rather avoid.
