Dogs Defecate In Alignment With Earth's Magnetic Field

Daniel_Stuckey writes "But for whatever its worth, all that spinning is far from arbitrary. What dog owners witness is a small and furry version of the aurora borealis and a link between species and environment that's as holistic and beautiful as a dog pooping can be. A team of Czech and German researchers found that dogs actually align themselves with the Earth's magnetic field when they poop. Proving at least that they're really devoted to their work, the researchers measured the direction of the body axis of 70 dogs from 37 breeds during 1,893 defecations and 5,582 urinations over the course of two years, and found that dogs "prefer to excrete with the body being aligned along the North-south axis under calm magnetic field conditions." They fittingly published their results [abstract] in the journal Frontiers in Zoology ."

Furthermore, it seems likely that urination is more likely to be affected by things such as the location of uprights against which to piss than by the magnetic field. Urination is a social signal more than is defecation. So it seems plausible that the effect, if it's real, is more evident when fido takes a dump.

Frankly, I think the people who say animals can do these things are just full of crap.

      Different species have different senses, and levels of senses. Your eyesight is much, much keener than a dog's, although not as good as an eagle's; your sense of smell is much better than the eagle's, but nowhere near as good as the dog's. And the way brains with very different structures process the information is different too. Is that really so difficult to believe?

      And further to that note: my parents had a dog that could tell when my brother (diabetic) had low blood sugar. They had three dogs at that time and one of them would bark in the middle of the night if he was low. He could somehow tell while sleeping in their bedroom that he was having trouble from across the house. My guess is that his scent changed and the dog was especially sensitive to it, but that is pure speculation on my part.

      It's very likely that the blood sugar level has effects on the sweat consistency, and humans perspire a lot while sleeping.

The three dogs slept in different rooms, though this sometimes happened during the day when they were wandering around the house as well. After he alerted, if you opened the door to let that particular dog out, he would run to my brother's door and bark outside of it until someone went in to check on him. My current dog definitely does not do anything of that nature. She can definitely tell when I am not feeling well, though. Normally she is the neediest dog on the planet. When I am sick, she just lays at my feet and tries not to bother me. That is probably just her reading my body language, though.

      Why do we insist on speculating that animals have all of these magical abilities, like the ability to tell which way is north, ability to tell when an earthquake is coming, ability to tell when a person has cancer, etc? Humans are animals too, and yet we can't do any of these things (without tools).

      Nobody in science suggests that animals have magical abilities.

      They do, however, have many remarkable abilities that human beings lack. There is evidence to support all of the following:

      1. Some snakes, for example, can "see" heat (infra-red vision), allowing incredible resolution in targeting their attacks.
      2. Bats and several other types of animal can use sound waves to navigate in the dark (echolocation).
      3. Sharks, skates, and rays can sense electric fields (electroreception).
      4. Some animals that are capable of long distance migration are able to sense magnetic fields (including sharks).
      5. Some fish can communicate using electric fields (electrocommunication).
      6. Bees have an interesting ability to detect electric charge on flowers.
      7. Scorpions have vibration sensors tuned to the bands of vibration frequencies carried through sand by their usual prey.

      Incredible variation exists from one animal species to the next in the sense we human beings think of as touch, smell/taste, hearing, and vision, which can take very exotic forms in animals.

      In many cases, the sensory systems of animals greatly exceeds what human beings can do without the aid of tools (or even with the aid of tools!).

      None of this is magic.

      In the case of the sharks, for example, a specialization of the hair cell that works as an antenna has been evolved. Since the shark has lots of these antennas, it also has a sophisticated signal processing mechanism in the nervous system to allow the shark to resolve direction. Since all living creatures generate electric fields, this provides a guide for the shark in the final moments of its attack, permitting attack in murky waters or at night.

      There are many chemicals that are responsive to electromagnetic stimuli, and biological entities have evolved a variety to mechanisms to produce and use these chemicals. Human eyes, for example, have chemicals that respond to visual light (a form of electromagnetic radiation), allowing vision. Similarly, plants have chemicals that respond to light, this permits photosynthesis. The idea that a chemical can be used as part of a sensory receptor for an electric field is simply another application of this idea: not all that strange when you think about it.

      Magnetic sensing is still not well understood, but you can read about the current ideas on how this might work by doing a search on "magnetoception". Once you allow the ability to sense a magnetic field, you essentially have a tool for navigation relative to the Earth's magnetic field (a primitive version of which is the compass).

      Similarly, there are many chemical receptors that can be used to sense the presence of other chemicals. Often these involve complex organic molecules with a three dimensional shape that responds to the shape of other molecules on contact, much like a lock responds to a particular key. Many variations of this idea exist, allowing huge variation in the ability to sense chemicals (which human beings call "smell") from one creature to the next.

      The usual search engines will provide lots of information on this topic, or you might get a book on animal physiology.

      The full limits of the capabilities of animal sensory systems are something we're not even close to understanding at this point, and there's a lot of active research going on. Since most people know there's a lot we still don't understand, there's a lot of speculation concerning what these different sensory systems (and doubtless others we haven't discovered yet) might be capable of.

      Even within the human species, considerable variation exists from one person to the next with respect to the ability to use the standard human senses. Some of this is biological, some of this is a function of environment and habit.
