Dogs are the domesticated descendants of the Wolf. They have either the scientific name of Canis familiaris (domestic dog) as a separate species or Canis lupus familiaris (domestic wolf dog) as a subspecies of the Wolf. Dogs are in the family Canidae, the dog-like carnivorans or canids, while the genus Canis means “dog” and includes wolves, dogs, coyotes and jackals. Their subfamily is Caninae, or canines, while their tribe is the dog-like or “true dog” tribe Canini and their sub-tribe is the wolf-like canids of Canina.
Dog Characteristics
All members of the genus Canis have common physical characteristics. Bone structure, behavior and reproduction are just a few markers that are unique to canids. Dogs also have unique characteristics that distinguish them from wolves. You can use some of these markers to determine whether a canid is a wolf or a dog.
Canine teeth
Teeth are one of the easiest ways to identify a canine. Most canids (of the family Canidae) have 42 teeth, with a dental formula of:
3.1.4.2
3.1.4.3.
Other canid features
Canids generally share similar skull features, basic body shape, monogamous and pack behavior and retention of adult offspring.
Dog features
Dogs have a greater variance in behavioral and physical variation than any other land mammal, including wolves. Dogs have starch gel electrophoresis of red blood cell acid phosphatase. They also have smaller, compressed and crumpled tymphanic bullae. Physically, they have a more domed forehead and “stop” between the nose and forehead. Wolves have a more prominent temporalis muscle (the muscle that closes the jaws) and do not have dew claws on their back legs. Dogs lack a pre-caudal gland and go into estrus twice instead of once a year. Whereas dogs usually have brown eyes, wolves have amber or pale-colored eyes. Their skin is thicker and their paws are half the size of those of a wolf.
Some house plants are poisonous to dogs, including Begonia, Poinsettia and Aloe Vera. Many human food items are indigestible or toxic to dogs, such as chocolate, onion, garlic, macadamia nuts, xylitol and nicotine. Diet-wise, dogs are omnivores and can handle a diet with more starch in it than a wolf, which is more strictly carnivorous.
Dog Exceptions
There are several tribes of the subfamily Caninae. The dog-like tribe Canini is sister to the wolf-like tribe Vulpini. They are in the suborder Caniformia or Canoidea, the dog-like carnivorans. It stands in stark contrast to the cat-like carnivorans, the Feliformia or Feloidea suborder of Carnivora.
Types of Dogs
There are several types of dog groups that are classified based on what they were bred to do:
Sporting dogs
Sporting dogs were bred to help their hunters capture and retrieve game birds. Retrievers swim and focus on waterfowl, while setters, spaniels and pointers hunt game birds. Their coats are often thick and water-repellant to protect against the elements. Some examples of sporting dog breeds are Golden Retriever, Labrador Retriever, the Nova Scotia Dock Tolling Retriever, Cocker Spaniel and German Shorthaired Pointer.
Hound dogs
Hound dogs were bred to chase after warm-blooded, terrestrial prey. They are generally divided into sighthounds, who use speed and vision to chase jackrabbits and antelopes, while scent hounds can use their noses to trail raccoons and people. All have strong prey drives. Some examples of hound dog breeds are Bloodhound, Greyhound and Dachshund.
Working dogs
Working dogs were bred to perform tasks such as guarding families or pulling sleds and carts. The Boxer, Great Dane and Rottweiler and a few examples of working dog breeds.
Herding dogs
Herding dogs are a type of working dog along with service dogs. While herding dogs help herd livestock, service dogs help people with disabilities. However, they differ in that they were bred specifically to herd livestock, such as sheep, cattle and reindeer. Some are excellent for police and military work. A few examples of herding dog breeds are Border Collie, German Shepherd and Icelandic Sheepdog.
Terrier dogs
Terrier dogs were bred to be small in order to go after vermin hiding in the ground. They include terrier breeds, which have long legs to dig out rodents, and “bully” breeds, which were used for bull-baiting and now make companion dogs. Bull Terrier, Scottish Terrier and Welsh Terrier are examples of terrier dog breeds.
Toy dogs
Toy dogs were bred for their small size to be companion dogs. They are perfect for city dwellers or anyone living in a small house. A few examples of toy dog breeds are Chihuahua, Pug and Shih Tzu.
Non-sporting dogs
Non-sporting dogs do not fit into any of the other group types and were bred to be companionship animals. The Bulldog, Dalmatian and Poodle are a few examples of non-sporting dogs.
Dog-wolf hybrids
Dogs share a common ancestor with modern wolves. Many large dog breeds have been bred with wolves, such as malamutes and huskies. Some are sought by private citizens, while others have been used for security work. For example, the Russians in the late 1990s created a breeding program for wolf-dog hybrids called Volkosoby or Volkosob, which are used for border control. See a list of 8 dogs that look like wolves here.

The grey wolf is the closest living relative of the dog, with cross-breeding having occurred during the dog’s domestication. There is no agreement as to when dogs were domesticated, but the process occurred somewhere around 11,000 years ago when hunter-gatherers closely associated with live populations of aurochs, beer, sheep and goats after beginning an association with wolves.

Are Dogs really color blind?
No, they do not see in black-and-white. However, they are red-green color-blind.
