There are 5 categories of chronic diseases that dogs develop via the normal aging process. The causation of these major diseases is primarily the normal aging process or oxidative stress. Oxidative stress is induced by highly reactive oxygen species (ROS) and is considered to be a major cause of dog cancer, dog cardiovascular disease, dog osteoporosis and dog diabetes. Oxidative metabolism or cellular respiration is one of the key ways a cell gains useful energy. It is the set of the metabolic reactions and processes that take place in a dog’s cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP) , and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another. Dogs are biologically constructed as vigorous physical animals, furthermore their bodies are designed to be carnivores thriving on the nutrients derived from eating high quality proteins. A canine’s physical prominence becomes quickly evident as puppies become adults within 6 to 18 months. Canines experience 4 stages of life, with the size of the dog determining the length of each stage, the larger the dog the longer the stage. Puppyhood last between 6 to 18 months, the next stage is adolescence and then adulthood starting anywhere near the 3 years of age. The last stage that of a senior dog has the widest time range among different sized dogs ranging between 6 and 10 years of age. Generally a dog will experience very few health issues during the first 8 years of their life, if properly vaccinated they probably will not encounter any major health matters. However when dogs begin to age their malady free bodies begin to experience multiple chronic diseases. Our research at VitaHound has discovered the absence of fruits and vegetables in a dog’s diet deprives them of many nutrients that are preventative in nature to many chronic diseases. The process known as ROS is generated endogenously through normal metabolic activity, with diet effecting the rate and scope of stress put on a dogs various organs during this constant biological process. The nutrient lycopene plays a major role in disease prevention caused by the normal aging process in humans. Tomatoes and tomato products are the most common source for humans, the tomato is the worlds most consumed fruit ,people consume 60 million tons a year. Watermelon, grapefruit, apricots, and red peppers are all foods containing significant amounts of lycopene, unfortunately dogs do not consume fruits in their diets especially those containing lycopene. The bioavailability of nutrients is important in determining the best source for obtaining those nutrients. Lycopene in its natural trans form, such has in tomatoes is poorly absorbed by a the body, heat processing of tomatoes induces isomerization of lycopene dramatically improving the bioavailability. Substances whose electrons do not belong to a single bond or atom, but rather a group have a molecular structure termed conjugated double bonds. The double bond structure of substances such as lycopene is responsible for their antioxidant activity.
