There are many different types of dogs, and they all have a unique coat or fur. Not only has there been natural breeding, but professional shows and dog enthusiasts have also increased the numbers even further. The coats of today’s dogs differ in length, colors, and make-up that are distinct and attributed to the origins of each dog. Double coat dogs have two seemingly separate fur layers which are not the same as single coated dogs. The first one is closest to the skin and has its characteristics while the second or top coat, is of rough consistency. Dogs with a double coat should not be shaved, as it is unhealthy and unneeded. There are many physiological problems, as well as visual and functional which will be discussed in further detail. The vast amount of kinds of dogs has been a topic of much speculation. The origins go back very far in history and unfortunately, it is close to impossible to say precisely where it all began. It is interesting, but the origins of dogs are almost as unspecified, like those of humans. Just as people, dog’s ancestors, wolves, have developed different characteristics, about the area they inhabited. The most common and accepted view is that dogs evolved from wolves by interbreeding. The modern research has provided information that wild animals would get domesticated as far as ten to fifteen thousand years ago. Speculation and reasoning suggest that animals were used by civilized human beings for many reasons. Some of them include working in partnerships as guard dogs, cattle shepherds, aided in hunting, transportation, fur and in some cases, a food source. Companionship was another reason, as certain species have proved to be reliable and of “good company.” It took many thousands of years domesticating wolves, foxes and other types of dog-like wild animals for modern dogs to emerge. Since wolves would often eat people’s leftovers, they became acclimated to the presence of humans, and it is suggested that some of these traits were genetically passed on to the next generation of wild animals. It was a slow process, but nonetheless, wolves and wild dogs became one of many animals that were domesticated (Ostrander 11). A large part of animal’s qualities is attributed to the unique climate and general geographic location that have created specific characteristics allowing for most adaptation and assimilation. Some species that were in the northern region had to adapt to cold conditions and thus, have developed an intricate system of heating and cooling down, as well as the uniqueness of fur. Shiba Inu is one such example that originated in Japan, and it has a double coat. It is considered to be one of the oldest dog breeds in the modern world. The ancestors of Shiba Inu were used for hunting many types of game. Supposedly, they could be effective for hunting smaller animals and birds but also larger ones, such as boar, dear or even bear. This shows that the breed is very diverse and can be trained to fit certain qualities that people need. At one point during the Second World War, the breed almost became extinct but was later saved by interbreeding bloodlines. The dog is of small to medium size and varies in color, from red and sesame to black, brindle or a mix of several colors and white patches. The unique f
