Feeding table scraps to a dog is generally not recommended, at least in excess. Dogs get ample correct nutrition from their natural, normal diet. Otherwise, just as in humans, their diet must consist of the appropriate mix of nutrients, carbohydrates, and proteins, with the appropriate mix to provide all of the minerals and vitamins that they need. A human diet is not ideal for a dog: the concept of a “balanced” diet for a facultative carnivore like a dog is not the same as in an omnivorous human. Wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, the scraps often consist of fat rather than meat protein, which in excess is no better for dogs than it is for humans. While not all human delicacies are acutely toxic to dogs (see above), many have the same chronically unfortunate results as they do for humans. Lastly, many people overfeed their dogs by giving them table scraps and human food such as ice cream. Dogs will usually eat all the scraps and treats they are fed, which is more than often too much food.The result of too much food is obesity, an increasingly common problem in dogs in Western countries, which can cause numerous health problems just as it does in humans, although dogs are much less susceptible to the common cardiac and arterial consequences of obesity than humans are. According to a study published in the Journal of Veterinary Internal Medicine, the prevalence of obesity in dogs is between 22 and 40 percent.[32]Additionally, the feeding of table scraps directly from the table (as opposed to taking scraps after the meal, and giving them in the dog’s food dish as a treat) can lead to trained begging behavior on the part of the dog, or even encourage the dog to reach up and take food directly from the table (another trained response). These are normally seen as undesirable behavioral traits in a dog.
Obesity can be a sign of other serious ailments such as Cushing’s Disease which is characterized by weight gain, appetite increase and lethargy in primarily older dogs.
A modern trend in canine diets is raw feeding of whole meats, bones and little filler material.
Most store-bought dog food comes in either a dry form, also known as kibble, or a wet canned form. Dry food contains 6-10% moisture by volume, as compared to up to 78% in canned food. Semi-moist foods have a moisture content of 25-35%. Pet owners often prefer dry food for reasons of convenience and price. Besides the lower price, dry pet food can also be left out for the animal to eat at will over the course of several days; whereas canned food spoils or becomes unappetizing after several hours. On the other hand, canned food has a longer shelf life than dry food. Canned food can also contain more protein and fat than dry dog food.
Pets have the ability to stimulate their caregivers, in particular the elderly, giving people someone to take care of, someone to exercise with, and someone to help them heal from a physically or psychologically troubled past.[10] Having a pet may help people achieve health goals, such as lowered blood pressure, or mental goals, such as decreased stress.[11][12][13][14][15][16] There appears to be strong evidence that having a pet can help a person lead a longer, healthier life. In a study of 92 people hospitalized for coronary ailments, within a year 11 of the 29 without pets had died, compared to only 3 of the 52 who had pets.[10] A recent study concluded that owning a pet can reduce the risk of a heart attack by 2% and that pets are better than medication in reducing blood pressure.[citation needed] Owning a pet can also prolong survival of a heart attack.
