Dogs have four legs, not two arms.
Dogs are very intelligent animals and they can learn to do almost anything!
They can be trained to do tricks, fetch things, guard your home or even work as a therapy dog.
All these skills require the dogs to understand what you want them to do and then do it.
But how do they know?
In this article I’m going to explain how dogs learn by watching us humans do things and then using that information to help them perform tasks on their own.
The History of Dogs
“My dog has a broken leg!” is one of the most common phrases that people use when they see their dogs limping around or laying down on the floor with a limp.
However, this is actually caused by a different problem than what you might think.
While many people believe that it is because of a torn ligament in one of the dog’s legs, this isn’t the case and instead it is because of a condition known as luxating patella (or “luxating kneecap”).
This occurs when the kneecap becomes dislocated from its normal position inside of the knee joint and can cause severe pain for your pet.
Thankfully, there are some things that you can do to prevent this from happening, such as keeping your dog active, giving them plenty of exercise, and making sure that they don’t get too hot.
But if it does happen, you should know how to treat it.
Below you will find out more about the history of dogs and why they have four legs.
The Evolution of Dogs
There are many myths about dogs.
Some say that they were created by God, while others believe that they evolved from wolves.
The truth is that dogs are a species of the Canidae family which includes foxes, jackals and coyotes.
They are also known as canines, but this name comes from the Latin word for dog.
However, there is no evidence to support the idea that dogs evolved from wolves, rather it has been found that they developed separately from other mammals.
Scientists agree that dogs originated in Africa around 40 million years ago.
This was before humans started using tools and hunting with spears and arrows.
They lived in packs and hunted large prey such as elephants.
When their food supply became scarce, they turned to scavenging instead.
In order to do this, they had to find new ways to communicate with each other.
These methods included barking, howling and growling.
Eventually, these sounds evolved into words, and soon after that, people began developing the ability to speak.
Around 15,000 years ago, the first domesticated dogs appeared on Earth.
These dogs had short hair and were smaller than modern-day dogs.
For thousands of years, man and his dogs worked together.
However, during the Middle Ages, the relationship between man and his dogs changed drastically.
This was due to religious reasons.
Many churches were against working animals because they believed that they deserved better treatment than slaves.
As a result, owners began abandoning their dogs when they went traveling or hunting.
It wasn’t until the nineteenth century that people started caring for their pets again.
Nowadays, dogs live longer lives than ever before.
They are more popular than ever before, too.
For example, in 2013, there were approximately 6 billion dogs in the world.
Although there are still many dogs that don’t get enough attention, the number of dog owners continues to increase.
The Anatomy of Dogs
In the beginning there was only one dog.
Then God created dogs and said, “Let them have a friend”.
The first dog replied, “I don’t need a friend. I am a dog. I can do everything by myself.”
So God said, “Okay, but if you want to be my friend, then you must follow these rules.
You must have four legs, two ears, and a tail.
And you must not talk back to me or get on my furniture.”
Then God gave the first dog his six senses (he could hear, smell, taste, see, touch, and feel).
He also gave him a brain that would help him understand what he saw, heard, smelled, tasted, felt, and touched.
Finally, God made the first dog smarter than the other dogs so that he could learn things faster.
After all, he had to make friends with his own kind as well as with humans, and he needed to know how to behave in order to fit in.
So, when it came time for the second dog to be created, God took the first dog and made him into a woman.
She looked very much like the first dog except she had long hair, which covered her body.
Then God made her pregnant and gave birth to many puppies.
When they were born, the puppies had fur that was all different colors.
Some had black fur, some brown fur, some red fur, and some yellow fur.
They each had their own unique look and personality.
But after a while, some of the puppy’s fur fell out because it was not properly attached.
This left the puppy looking like an old man who just got out of bed.
His hair was matted and full of dandruff.
It was hard to tell whether the puppy was male or female.
The Male Dog
Soon, the pup grew up and became a young male dog.
He began to chase cats, squirrels, birds, and anything else that moved.
One day, he decided to go hunting.
He went out into the woods and found a deer.
He chased the deer until it ran away from him.
The deer ran into a tree, and since the deer was bigger than the tree, it pushed down the tree.
When the deer stopped running, the tree fell over on top of it, pinning it to the ground.
The tree crushed the poor deer.
The deer died.
After this incident, the young male dog decided never to hunt again.
Instead, he would live off of garbage and eat grass.
He didn’t care about having a family, a job, or any other responsibilities.
He lived life on his terms.
There was no one to tell him what to do anymore.
The Female Dog
Meanwhile, a few miles away, another male dog was playing with a ball.
He chased the ball around the yard.
Suddenly, he caught the ball and threw it at a hole in the fence.
The ball rolled through the hole, landing inside the house.
The owner of the house thought that someone was breaking in, so he grabbed his gun and shot the dog.
Unfortunately, the bullet hit the dog in the head and killed him.
When the owner realized what happened, he ran outside and tried to pull the dead dog out of the hole in the fence, but it was too late.
The dog was already dead.
After this event, the female dog decided that she wanted to have children.
She knew that she would have to give up being independent if she wanted to have babies.
So she decided to find a nice man who loved her, and she would leave the rest to fate.
She found a very nice man named Joe.
He was tall and handsome.
He was good-looking, and he loved her.
They married and had lots of children.
As long as Joe treated her right, she was happy.
The Physiology of Dogs
There are a lot of myths and misconceptions about dogs.
One common myth is that dogs have only two limbs.
This is simply false.
They have four legs.
Another popular myth is that dogs can’t climb stairs.
This is also false.
Some breeds of dog can easily climb stairs but most require some assistance.
The breed of dog will determine how well it climbs stairs or steps.
Collies for example are very good at climbing stairs.
Another myth is that dogs sleep with their heads on the ground.
This is untrue as well.
Most dogs sleep in a reclining position.
Their head is elevated from the floor.
A few breeds such as the golden retriever sleep with their head on the ground.
Golden retrievers often get a bad rap because they are so loyal to their masters but this is misleading.
Golden retrievers do not like to be left alone and may become aggressive if left alone too long without human contact.
A famous myth is that dogs eat grass.
This is true.
Many breeds of dogs and wolves do eat grass.
Wolves actually eat the roots of plants which contain a high concentration of nutrients.
When dogs eat grass, it is usually after a meal or when they are hungry.
It is not an everyday occurrence.
Dogs are omnivorous animals meaning they eat both plants and meat.
Omnivores include all mammals, reptiles, amphibians, birds and fish.
Carnivorous animals eat meat.
Meat comes from the flesh of dead animals.
Herbivorous animals eat plant material.
Plant matter consists of vegetables, fruits, grains and legumes.
Omnivores cannot survive without eating plants and meat.
Dogs have four main types of teeth.
Canines or fangs are the largest teeth found in any animal.
They are used to tear up prey and other animals.
They are sharp and pointy.
Next are incisors, which are small pointed teeth located behind the canine teeth.
Incisors help dogs chew food.
The third type of tooth is molars.
Molars are flat triangular shaped teeth that grind down food.
Finally, there are premolars.
Premolars are smaller than molars and are located between the canine and first molar teeth.
These teeth aid in chewing food.
There are also wisdom teeth located in the back part of the mouth.
These teeth are not always present in every individual.
Wisdom teeth usually appear sometime during puberty.
The purpose of these teeth is to break down food before swallowing.
Wisdom teeth are typically removed by veterinarians but sometimes they cause problems in dogs.
If you see your dog biting its own tongue or gums, it might be wise to visit your veterinarian to make sure everything is okay.
Dogs have different hair lengths depending on the breed.
In humans, hair grows in length from top to bottom.
But in dogs, hair grows in length from top to side.
Longer haired dogs are called longhairs and short haired dogs are shorthairs.
Longhairs tend to grow faster than shorthairs.
Longhaired dogs are better suited for colder climates while shorthaired dogs are better suited for warmer climates.
Shorthaired dogs are also more prone to sunburns.
The Behavioral Characteristics of Dogs
The behavioral characteristics of dogs are many and varied.
Some of the most common traits include:
Sensitivity to pain
A strong desire for affection
A sense of pride
An ability to discern between friend and foe
A willingness to work
Other behavioral characteristics of dogs include:
Aggression towards other animals
Unwillingness to be alone
I think I’ll go with the latter for now.
The former is a bit too far-fetched.
But you can always come back to this article in a few years and see if my conclusion has changed.
For now, let’s move on to other interesting dog facts!
