"The most widespread form of interspecies bonding occurs between humans and dogs"[136] and the keeping of dogs as companions, particularly by elites, has a long history.[142] (As a possible example, at the Natufian culture site of Ain Mallaha in Israel, dated to 12,000 BC, the remains of an elderly human and a four-to-five-month-old puppy were found buried together).[22] However, pet dog populations grew significantly after World War II as suburbanization increased.[142] In the 1950s and 1960s, dogs were kept outside more often than they tend to be today[143] (using the expression "in the doghouse" to describe exclusion from the group signifies the distance between the doghouse and the home) and were still primarily functional, acting as a guard, children's playmate, or walking companion. From the 1980s, there have been changes in the role of the pet dog, such as the increased role of dogs in the emotional support of their human guardians.[144] People and dogs have become increasingly integrated and implicated in each other's lives,[145] to the point where pet dogs actively shape the way a family and home are experienced.[146]
Dogs have been described as carnivores[117][118] or omnivores.[17][119][120][121] Compared to wolves, dogs have genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet.[19] Based on metabolism and nutrition, many consider the dog to be an omnivore. However, the dog is not simply an omnivore. More like the cat and less like other omnivores, the dog can only produce bile acid with taurine, and it cannot produce vitamin D, which it obtains from animal flesh. Also more like the cat, the dog requires arginine to maintain its nitrogen balance. These nutritional requirements place the dog part-way between carnivores and omnivores.[122]
A dog groomer is a service professional who provides dog grooming and basic hygiene care for your dog. Dog groomers are typically animal lovers who are competent and comfortable working with a wide range of dog breeds and temperaments. Dog groomers are knowledgeable about the care needs for different kinds of dog coats. A poodle will have different haircut needs than a shih tzu, for example, so it pays to have a trained pro provide the proper cut. Good dog groomers know how to safely clean your dog’s teeth, bathe your dog, and cut their nails without going too short. They understand how to trim the hair from around your dog’s face, express anal glands, and clean your dog’s ears. Many people who choose dog grooming as a profession also pursue other dog services such as attending veterinary school, running a doggy day care center, working as a professional dog walker, and more.
The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety.[197] Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans.[198] One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not.[199] In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.[200]
Soak your dog thoroughly. Make sure your dog's coat is completely wet before you start applying shampoo to it. If your dog isn't afraid, you can buy and use a hose and water pressurizer attachment for the faucet. This is especially helpful if you have a large dog or one with a double-coat. AVOID getting water in your dog's ears. Water in the ears can cause an infection. Please be sure to only spray water/rinse water up to the dog's neck. The head can be cleaned separately (see below for instructions).
In domestic dogs, sexual maturity happens around six to twelve months of age for both males and females,[17][68] although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles semiannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation.[17] Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for more than one male to sire the same litter.[17]
The majority of contemporary dog owners describe their pet as part of the family,[146] although some ambivalence about the relationship is evident in the popular reconceptualization of the dog–human family as a pack.[146] A dominance model of dog–human relationships has been promoted by some dog trainers, such as on the television program Dog Whisperer. However it has been disputed that "trying to achieve status" is characteristic of dog–human interactions.[150] Pet dogs play an active role in family life; for example, a study of conversations in dog–human families showed how family members use the dog as a resource, talking to the dog, or talking through the dog, to mediate their interactions with each other.[151]
The most popular Korean dog dish is gaejang-guk (also called bosintang), a spicy stew meant to balance the body's heat during the summer months. Followers of the custom claim this is done to ensure good health by balancing one's gi, or vital energy of the body. A 19th century version of gaejang-guk explains that the dish is prepared by boiling dog meat with scallions and chili powder. Variations of the dish contain chicken and bamboo shoots. While the dishes are still popular in Korea with a segment of the population, dog is not as widely consumed as beef, chicken, and pork.[174]
Raised grooming tables and bath tubs keep you from bending your back and hurting yourself. Any table or sturdy surface could serve as a makeshift grooming table, but always have a non-skid surface for the dog to stand on. That means no wheels on the table. Hardware stores usually carry rubber-backed or rubber runners sold by the yard that you can cut to size of any surface.
There are a vast range of commodity forms available to transform a pet dog into an ideal companion.[147] The list of goods, services and places available is enormous: from dog perfumes, couture, furniture and housing, to dog groomers, therapists, trainers and caretakers, dog cafes, spas, parks and beaches, and dog hotels, airlines and cemeteries.[147] While dog training as an organized activity can be traced back to the 18th century, in the last decades of the 20th century it became a high-profile issue as many normal dog behaviors such as barking, jumping up, digging, rolling in dung, fighting, and urine marking (which dogs do to establish territory through scent), became increasingly incompatible with the new role of a pet dog.[148] Dog training books, classes and television programs proliferated as the process of commodifying the pet dog continued.[149]
