How Dogs Know the Time
It has something to do with the fiery star, even though it may not be able to see the sun through the window.Of course, dogs can't look at a clock and tell that it is 5:00 p.m. But they do know the events that usually occur at that particular time. And this is another reason why dogs are aware of the time. For example a trivial event - your water heater makes that boiling sound at the same time every day. Thus this sound signalizes to the dog what time of day it is.So this is it. Dogs really have the ability to know the time within 15 minutes and know the difference between the lengths of time. And you'd better not to make your favorite pet wait too long!This makes my doggy tear the books for reading that I keep near my bad. So in this manner my dog shows that it is disappointed that the time of our long walks ended for a while.Stories like these are rather common. The reason for such a wonderful sense of time lies in the biological clocks that dogs have in their brain. These biological clocks are cells deep in the brain that produce enzymes, and then break down the enzymes within a 24 hour period. So dogs just know what time of day it is.Another time orienteer for a dog is the sun.
