Dog's Physical Appearance

It can be argued that along with cats, dogs were one of the first animals to become domesticated. For approximately 10,000 years humans and dogs have more than co-existed, they have developed a special bond unlike any other animal has developed with us. Today hundreds, if not thousands of breeds of dog exist. Although this fact remains true, all dogs belong to the Canis Familiaris family within the animal kingdom. Despite any tamed, domesticated, or docile tendencies, all breeds of dogs have traits that are derived from their wild ancestors and to this day many of those traits still exist and in fact, are quite important to the dog’s survival and mating techniques. Some of the more prominent survival tactics include digging, burying, being

Dogs were not always how they are today. Almost 35,000 years ago, they were wolves. Humans saw most wolves as a threat. Even though they saw each other as enemies, there was a point where they helped each other. This is what helped them evolve. It all started when wolves went to human camps to devour some scraps of food. Because of this, the wolves were healthy and had many pups. The pups inherited the parents' habit of snacking on leftovers. This cycle repeated over and over. Wolves were willing to get closer to people. Humans soon realized that wolves make very good guards because they protected the humans from many dangerous animals. As a result, wolves living near the humans started to change.

    Dogs have been domesticated for over 10,000 years. Food from the humans would bring the dogs to them, and the dogs would bark at predators when they came so the people started to feed the dogs to keep them around. In the 1’st century AD in China Roman mosaics show evidence of the present day Pekingese and Roman ladies also had lap dogs. They believe the dogs warmth cures stomach aches. The earliest evidence of any domesticated dog is a jawbone found in Iraq in a cave about 12,000 years ago. We know it is a jawbone of a dog because a jawbone of a wolf is smaller and the teeth is smaller.

“A dogs sense of smell sometimes out perform X-Rays and CT scans at detecting cancers at an early stage by simply smelling a persons breath or urine.” Everyone is able to breed a dog to function in many different ways and for many different reasons. Mow explains how this is possible through his short movie Science of dogs. “Because of intensive selective breeding by cross breeding different breeds for different distinctive types of physical appearances and behavioral attributes; you will soon create the dog you were looking for and it will also have a consistency of creating the same breed of dog by creating a new genetic code in the dogs DNA”. For example there is one breed of dog that has the best sense of smell in the entire world and they were created for one job and one job only. Klim Sulimov explains what dog this is and how it was formed on the Science of Dogs, “The Sulimov dog has the best sense of smell in the whole entire world, and they were successfully created to identify explosives, he bred a Jackal with a Lapland Herding Hound, a Reindeer Herding Hound, a Fox Terrier, and a Spitz. Creating a dog that is highly trainable dog and a superior snout”. All these hybrid breeds are so successful because of how the dogs DNA is formed. The discovery of deciphering the dog genome was discovered by the Researchers at the National Institutes of Health on The Science of Dogs “Every piece of DNA is made up of four different chemical components

Have you ever had a dog? Do you know where dogs came from? Well, did you know that a million of years ago dogs did not exist. Back, then the dogs were wolves that disliked people. The relationship between dogs and humans has changed over time because over thousands of years ago, the wolves evolved to dogs and the dogs soon became part of human families. That is why these days people want to have a dog as a pet.

As anyone who has seen a televised dog show can attest, some dogs are deformed in disturbing ways. One might look at the “excessively wrinkled skin of the Chinese Shar-Pei,” the “the flat face of a bulldog,” or the “low-slung eyelids of a Bloodhound” (PBS), and think, “That can not be healthy.” The fact of the matter is that these deformities are far from healthy. As the Public Broadcasting Service (PBS) points out, the Shar-Pei’s skin (due to it’s “excessively wrinkled” nature) is prone to skin infections, the Bloodhound’s droopy eyes are practically magnets for eye infection, and the Bulldog’s face is so squished that it can never breathe correctly. While these deformities may be more obvious, overly large or small pedigree dogs have their own slew of health problems (Rooney and Sargan). As Rooney and Sargan disclose, very small dogs (known as toy breeds) often have dislocated kneecaps, heart problems, and trouble staying warm. Big dogs, such as Great Danes, can suffer from heat prostration and orthopedic issues (Rooney and Sargan). According to Rooney and Sargan, almost every purebred breed of dog is more likely to have at least one genetic disease compared to mixed breeds. However, physical problems are not the only thing purebred dogs have to face: behavioral problems are also more prevalent in certain breeds (Rooney and Sargan). Rooney and Sargan reveal that

Humans and dogs have long shared a bond that was based on function. Early dogs that were the least valuable and useful did not make it into today’s time. On the other hand, the most valuable and helpful of dogs remained and created others like them. Ultimately, breed predecessors were produced by breeding the best hunters to the best hunters and the best guards to the best

Canines have the ability to serve as seeing-eye dogs, firedogs, service dogs or just a playful, loyal companion. The closer the dog and human’s relationship is, the stronger the feelings between them are. Canines have a talent of recognizing dangerous situation and being there for humans in their time of

A long time ago, dogs were once wolves, and they worked for humans. Over the millennia, wolves have evolved into dogs, and dogs have become friendlier. The way wolves have changed over time into dogs have been very noticeable. Although, the arctic grey wolf didn't turn into Cavalier King Yorkshire Terrier overnight. The reason the two, dogs and wolves, have changed are plentiful due to the changing relationship between humans and dogs. It cannot be denied.

There are similarities between dogs and humans. These will include homelessness, perseverance in the fight for survival, the apparent lack of organizational hierarchy among our species, and the instinctual survival abilities that have been lost through the evolution of domestication. All these became apparent to me when I started to compare the dogs that Randy has encountered. Consciously or subconsciously, I’ve come to the realization that humans are not very different from dogs. In the sense, both species have progressed through the evolution of domestication.

Their skulls, teeth, and paws shrank, their ears flopped, they gained a docile disposition, becoming both less frightening and less fearful. They learned to read the complex expressions that ripple across human faces. Even though some dogs don’t look alike, they share some of their genes, and belong to the same species. Compared with equally sized wolves, dogs tend to have smaller skulls and smaller brain. The teeth in wolves are larger than the dog’s teeth. The skin in dogs is thicker than wolves. Wolves are smarter and are more are in their environment than dogs. But when it comes to sociability, dogs are more friendly with other animals and as pets. The Saarloos Wolfdog carries more gray wolf DNA than any other dog breed. The gray wolves live in many places, like in deserts, grassland, forest and arctic tundras. Dogs were developed to do different tasks and for the men needs, like herding, droving, pulling, hauling, herding, hunting, rescuing and guarding. Some dogs were used as luxury item, they were viewed by others as an status

For millions of years dogs have remained a constant companion of man. Bred from the aggressive and formidable Gray Wolf tens of thousands of years ago the domestic dog now lives in many homes across the world. Where in the far distant past the domestic dog was bred as a guard animal, a beast of burden, and even a food source the dogs of today are bred for a far more endearing purpose-companionship and love. Finding a pet dog that is more of a joy than a chore is necessary when asking: How much is that puppy in the window?

Cute, fun, loving, cuddly, outgoing; these are only a few words to describe the animals that we have come to know and love as a part of our families. Dogs have been man’s best friend for hundreds of years and were the first animal to be domesticated because they are great as companions, highly intelligent, and were found to be very useful in human’s everyday lives. Even though they made excellent house pets they were highly successful at working side by side humans as well. They are not limited to being just best friends, but they have been found to be protectors and saviors as well, to their owners, others people and even other dogs too. One type of working dogs in

There are several theories on how the evolution from wolf to dog came about. One theory is that the human environment attracted wolves. Wolves started following people around to take advantage of food scraps that were left behind. Eventually, wolves lost fear of people, and people lost fear of wolves. The benefits of this new relationship were not just one way. Wolves also helped humans by sniffing out prey and helping them hunt. Success likely meant the humans would share their food with wolves. This is a very popular theory, but it has been disputed. Archeological digs show that the early dogs were not eating the same mammoth meat that the humans were eating. Instead, their main diet consisted mostly of less popular human meat such as reindeer. The prehistoric dogs also had many broken teeth and severe facial wounds. Although these injuries could be from fighting with other dogs, many scientists believe the dogs had been beaten with sticks, leading many to assume the relationship between man and prehistoric dog was not as companionable as the theory would suggest.
