Do insects have bones?


If you could look inside an insect’s body, you wouldn’t see any bones. But insects do have skeletons!  Insects differ from creatures with back-bones, such as humans, horses, dogs and fishes.  These animals have hard skeletons inside their bodies. Your skeleton is made of bone, and the rest of your body is shaped around it.

An insect’s skeleton though, is a tough outer shell.  It provides support and protection for the insect’s soft insides.  Some insects, especially beetles have hard, heavy skeletons.  Others, such as butterflies have light, thin skeleton. – Dick Rogers

Can dogs see colors?


Our world about us is so filled with color that it is hard to believe that dogs cannot see colors, at least by human standards.  What dogs probably do see is the world in black and white and many shades of gray—much like what you see when you watch a color television program on an ordinary black-and-white TV screen.

Cats, mice, horses and cattle cannot tell one color from another, and neither can deer or most other wild animals active at night.  During the evening, when the world is a shadowy, colorless place, the ability to see colors is not important for survival. – Dick Rogers

Can dogs hear better than people?


Dogs can hear many sounds that our ears cannot hear.  If you have a pet dog, then you know what keen ears dogs have.  A dog will bark at approaching footsteps long before they are heard by his master.

It’s easy enough to hear noises.  You can hear with noises, loud noises, and in-between noises.

All sounds are produced in the same way.  Every kind of sound begins with the vibration of something.

When a bell is rung, the bell shimmers and shakes.  We say, that it “vibrates.”  When a lion roars, the voice cords in the lion’s throat vibrate.

These vibrations disturb the air and cause sound waves that travel outward like ripples in a pond, and when they reach your ear they make part of your ear vibrate, too.  That’s when you hear the sound.

But we cannot hear all the sounds around us.  Our ears can only hear certain sound vibrations.

Some animals, like the dog, can hear sound vibrations that humans cannot.  The “silent” dog whistle makes a sound vibration so high and so shrill that you can’t hear it – dogs can!

A cat can hear even higher sounds.  And the bat can hear the highest sounds of all. – Dick Rogers

Why do dogs bury bones?

Dog Bury A Bone

If we remember that our dogs are descended from dogs which lived in a wild state long ago, we can better understand some of their habits.

When a dog buries a bone, it may be because its wild ancestors often buried or cached what food they couldn’t eat in one meal to store it for a future meal, a habit which was necessary to life.

By burying food, a dog digs the hole with its front feet but covers the food with its nose.

Today’s dogs have many of the instinctive habits of their wild ancestors.

For example, a dog may turn around several times before lying down, in much the same way wild dogs trample the grass to make a sheltered bed.

When a dog bays at night, it is probably an ancestral habit from the time when all dogs ran in packs like wolves.

A dog may even roll in fifth to hid its own odor—a trick learned by dogs who hunted ages ago. – Dick Rogers
