Feeding A Normal Dog or Cat

Owners can prepare diets for their pets with no more difficulty than for their own needs. The following diets contain foods that humans commonly use for their own diets. This section provides recipes for feeding adult dogs and cats a maintenance diet. Also included are diets for growing puppies and kittens. Some very active or hard working dogs require greater amounts of energy than growing animals. Recipes are given to sustain the needs of such animals.

Preparing Diets
Unless stated the following diets are all nutritionally balanced and complete. Each recipe lists quantities of proteins and fats that cannot be compared with those listed for commercial pet foods. Commercial products list higher concentrations for proteins. These foods have higher levels because digestibility and availability for their proteins are poor compared to those in owner-prepared recipes. Commercial pet foods need up to twice as much protein than owner-prepared diets because it takes that much to supply amino acid requirements. The amino acid content of owner-prepared diets is also closer to ideal so that less protein is needed to provide an animal's needs. Fat content varies with each diet. In many recipes vegetable oil is the primary source of fat. If a pet gains weight and its body fat exceeds the ideal, dietary oil is reduced. Most diets contain other sources of fat that provide essential unsaturated fatty acids, so eliminating vegetable oil will not result in a deficiency. The diets contain more than required amounts of sodium chloride but much less than commercial pet foods which contain approximately one percent salt. Iodized table salt can be used to add flavor if desired.

Vegetable Supplements
To each of the following diets vegetables can be added. They are not necessary to make a diet nutritionally complete. The number of calories added with the inclusion of vegetables can be found in the following table.
Uncooked vegetables contain few available calories. If they are included or fed as snacks it is not necessary to calculate their caloric contribution to the pet's intake. They provide additional fiber.

Vitamin and Mineral Supplementation
When the diet cannot be balanced with natural foods to provide vitamin and mineral requirements, it is necessary to supplement with a vitamin-mineral preparation. Supplements prepared for pets are used unless they are not tolerated. The common supplements prepared for pets contain flavoring agents, binders, fillers, and other additives that can cause gastrointestinal problems in animals with allergies. Such additives are less likely to be used in supplements prepared for humans. The amount of vitamin and mineral supplement to give is  based on an animal's caloric intake or body weight. Supplements formulated for an adult human supply the average needs for a person weighing much more than most dogs. Thus, a vitamin-mineral tablet for a human contains too high concentrations of ingredients for most dogs. Some may believe that excessive amounts of vitamins and minerals are not harmful; more is better than the required amounts. Excessive amounts of most vitamins and minerals are not harmful. An excess amount of vitamin A or D is harmful, however. Excess vitamin A is toxic to the liver, especially when a toxin is present or the liver must detoxify a chemical (drug). Excess vitamin D is also toxic in that it stimulates absorption of excess calcium. Excess dietary copper causes large amounts to accumulate in the liver. If the liver is unable to excrete copper it can cause severe liver damage. Vitamin supplementation is based on caloric consumption. Each 1000 kilocalories of food should contain a certain level of each vitamin. The recommendations are more precise for growing animals than for adults. All of the diets in this website contain vitamins at levels based on the caloric content. It is not necessary to supplement any diet with vitamins unless the recipe states that a supplement is required. It is also possible to make vitamin recommendations based on an animal's body weight. The following tables give vitamin recommendations based on an animal's weight. The second table gives adjustments for using human vitamin-mineral preparations based on an animal's size or food consumption. Although a growing animal has greater requirements than an adult, the vitamin content based on amounts per 1000 kilocalories is almost the same for growing and adult animals. The growing animal receives more vitamins because it eats more per pound body weight. Cooking destroys vitamins so vitamin supplements are added after cooking and before feeding.

Vitamin-mineral supplements are formulated for small animals so they provided needs for their varying body size. Examples include PET-TABS® and VI-SORBITS® made by SmithKline Beechmam. The former contains ingredients such as liver (beef and pork), fish meal, wheat germ meal and a number of other additives and fillers that could cause problems in animals with gastrointestinal problems. If these are tolerated they can be given more easily that human vitamin-mineral preparations. The animal preparations are not regulated as closely by governmental agencies for potency etc. For animals with food intolerances and allergies human non-allergenic preparations can be given and the amount to use in any diet is one-fifth of a capsule or tablet for each tablet of pet vitamin-mineral tablet called for in a recipe. An example of a non-allergenic human preparation is a multiple vitamin-mineral product made by Nature’s Way Products, Springville, Utah.

The diets for dogs that do not contain sardines lack vitamin B12, even when a vitamin-mineral supplement is added. Sardines are added to provide vitamin B12. That vitamin can also be added by including liver in the diet. One reason for not using liver is that it contains very high levels of vitamin A and sometimes excess vitamin D. Excess amounts of either vitamin are toxic. Thus, liver should not be given daily to a dog or cat. Sardines also increase palatibility; some diets lack flavor. If sardines are not fed, vitamin B12 tablets can be added. (Removing 2 tablespoons sardines from a diet lowers the caloric content by 68 kcalories, protein content by 6.2 grams and fat by 4.6 grams.) Most tablets contain 1000 micrograms which is 50 times more than a dog requires. It is probably not necessary to give this vitamin more than once a week. Many dogs and cats eat diets very deficient in vitamin B12 for months and sometimes for years, and signs of vitamin B12 deficiency are not seen. Thus, it is not important to supplement owner-prepared diets with additional vitamin B12.

Mineral supplementation is based on the number of calories consumed. Each 1000 kilocalories of pet food should contain a certain level of each mineral. The recommendations are more precise for growing animals than for adults. All of the diets in this website contain minerals at levels based on the caloric content. None of these diets need to be supplemented with minerals unless the recipe states that a supplement is required. It is also possible to make mineral recommendations based on an animal's body weight. The following table gives mineral recommendations on an animal's weight. It is apparent that a growing animal has greater requirements than an adult. The mineral content based on amounts per 1000 kilocalories is almost the same for growing and adult animals. The growing animal gets more minerals because it eats more per pound body weight. Bone meal provides a balanced ratio of calcium to phosphorus and in addition provides trace minerals. Bone meal powder is readily available but the dosage may vary considerable. The recipes in this website contain bone meal powder manufactured by KAL® where the amount used is based on a level teaspoon of the product weighing 6 grams. Recommendations on how much bone meal to use on the labels for different products are often very much more than an animal's requirement. Thus, it is important to determine the calcium and phosphorus content from any product's label and judge whether the recommended amount of bone meal to give agrees with meeting the pet's requirements.

Determination of Caloric Needs
Determine a pet's ideal body weight. Refer to tables on caloric requirements to find the number of calories to feed each day. The following recipes show how to prepare an amount for which its caloric content is given. That amount is appropriate for an adult pet at a certain weight. If the size of the recipe is inappropriate for any animal, reduce or increase the size of the recipe to meet its nutritional needs.

It is possible to substitute other pastas for macaroni without changing the nutrients provided. In comparing these diets, feeding macaroni provides a medium size dog eight grams of protein more than rice or potato. The digestibility of macaroni is poorer than for rice or potato.

Vegetarian Diets for Adult Dogs

Completely balanced vegetarian diets can be fed to dogs without fear of causing any nutritional deficiency. The digestibility of vegetable proteins is less complete than for proteins of animal origin. Vegetarian diets are usually less expensive than those containing animal protein. These diets require supplementation with vitamin B12, a vitamin found only in food prepared from animal sources. This vitamin can be given once a week.

Diets for Growing Dogs   

Growth requires greater amounts of protein, calories, vitamins and minerals. Puppies can double their body weight in a short time. A number of recipes follow that are based on using animal sources of proteins. It is possible to support a puppy's growth by feeding a vegetarian diet, some of which are included. Because vegetable and cereal proteins are not as well digested as animal proteins vegetarian diets need greater amounts of proteins than diets based on animal proteins.

Vegetarian Diets for Cats

Cats have always been carnivores. Cats have some unique nutritional needs that a strictly vegetarian diet cannot satisfy. They have a need for arachidonic acid that plants do not make. Thus, an animal source of this nutrient must be given. Cats also have a unique need for taurine because they cannot make it from other nutrients. Foods supplied from plant material contain no taurine. It must be supplied from a source where it is produced. In the following diets it is necessary to obtain taurine from a health food supplier and add it to the cat's diet. Because vitamin B12 is not produced by any plant sources of food, it must be added to the diet. If a cat is fed a vegetarian diet appropriate for human beings it is likely that signs of a nutrient deficiency will eventually develop.

Behavioral Problems

Behavioral problems can be associated with diet. Coprophagy is a relatively common problem in dogs fed commercial pet foods, especially dry foods. It is rare in animals fed owner-prepared diets or consuming food caught while hunting. Coprophagy is associated with feeding high carbohydrate diets, especially in German Shepherds. Coprophagy ceases in working dogs fed horse meat instead of dry dog food where caloric intake remains unchanged. Enough horsemeat is fed to reduce the diet's carbohydrate content from about 40 percent to about 25 percent. The problem is managed by feeding owner-prepared diets containing sufficient amounts of protein and relatively small amounts of carbohydrate. Instead of correcting the nutritional problem causing coprophagy, pets are often fed something to give feces an offensive odor and taste. Chemicals for parasite control are sometimes given orally to discourage coprophagy. Sodium glutamate mixed with a purified edible vegetable protein fraction is marketed with claims for curbing coprophagy. It also makes the odor and taste of feces offensive. If a pet eats fecal material of other animals, these preparations have no value.

Feeding Geriatic Pets1-4

Factors Insuring A Long And Happy Life

Pet dogs and cats live considerably longer today than in the past. Better care, especially medical care, is assumed to increase their life expectancy. Life expectancy is also genetically determined. Life span is unique for each animal species and for breeds within a species. Life spans varies greatly for canine breeds. Small breeds and very large breeds of dogs do not live as long as intermediate size breeds.

Environmental factors also influence life span of dogs and cats. They include airborne toxins, and toxic-contaminants in food and water. Toxic substances can reduce resistance to disease and directly injure tissues. The greatest exposure to toxic substances is through what is consumed. An animal can eat literally hundreds of pounds of foodstuffs yearly. Thus, quality of the diet is important in determining long life expectancy in dogs and cats.

Geriatric Diets

Manufacturers design some pet foods for aged dogs. Compared to diets for younger dogs, these have reduced fat and possibly increased fiber. Fat content is less because obesity is common in aged dogs and reducing dietary fat helps in weight reduction. Manufacturers give little consideration to improving dietary quality. Some believe that elderly animals digest and absorb a meal as well as young animals. That conclusion is based on older animals having few changes in digestive tract morphology. But digestive function changes with aging.

Protein Needs of Older Pets
Older dogs require more protein than younger adult dogs. Merely increasing dietary protein does not satisfy this increased requirement. Protein quality must also be improved to make dietary protein highly digestible.
Overall dietary composition is important for optimum protein digestion and absorption. Dietary carbohydrates and fiber reduce protein digestibility by delaying its digestion. Normally, high quality dietary protein is completely digested and absorbed in the small intestine, and little or no protein enters the colon. Delay in protein digestion can cause some protein to escape digestion and absorption. Excess unabsorbed protein entering the colon is degraded by colonic bacteria to non-nutrient substances. These substances are absorbed and must be detoxified for excretion. Some of these substances are biogenic amines. Their colonic concentration increases with increased dietary protein. Thus, in addition to poor quality pet foods not supplying adequate protein for aged dogs, they can also contribute to non-nutrient substances (some are toxic) because of poorer assimilation. High dietary fiber and poorly digested carbohydrates, such as in most cereal-based foods, aggravate this problem. Geriatric pets should be fed proteins with high biological value and high digestibility. This minimizes protein residue entering the colon where bacteria act on it to produce toxins. Protein requirements are satisfied by feeding 4.5 g of digestible crude protein per kilogram metabolic body mass (4.5 g/kg bw0.75) This level is 50 percent more than recommended for maintenance of adult dogs. However, commercial diets for adult maintenance often exceed this amount.

Caloric Needs Of Older Pets
Food is consumed primarily to satisfy energy requirements. Older dogs and cats need fewer calories because they are less active than younger adults. To maintain optimal weight in old animals, caloric intake can decrease to 80 percent of that needed for younger adults. Total caloric intake reductions must take into consideration that requirements for other nutrients may be unchanged or increased. As already noted, dietary protein must increase even if caloric intake remains unchanged. Needs may increase for some vitamins and trace minerals, but that is unproven. Vitamin E is most important to supplement. Aging is associated with many degenerative changes and vitamin E helps prevent damage.
Older animals are more likely to be overweight than younger adults. This greater tendency is specific for neither sex, and neutering is not significant in promoting obesity. The number of daily feedings is not a factor. Factors that do not make a difference include living with young children (who feed the pet frequently), raiding the garbage, or living with an older or younger person. The only significant factor associated with obesity in older animals is reduced physical activity.

Fat Digestion And Absorption
Fat digestibility and tolerance are not poorer in older dogs and cats but aging can delay fat absorption. Reduced fat intake is not necessary unless a weight reduction program is planned based on low-fat intake. Older animals require essential fatty acids so they should be given.

Carbohydrate Digestion And Absorption
Dietary carbohydrates are selected to increase digestibility for both starch and protein. Rice is the most completely digested carbohydrate. Dogs and cats poorly digest and absorb other grain cereals, the basis of most commercial pet foods. Although carbohydrate assimilation appears to be normal in older animals, in some dogs and cats it is associated with abnormal glucose regulation and signs of diabetes mellitus.

Nutrients Protecting Aging Animals5,6
Chemicals and nutrients play a role in development of and protection against disease. Cancer is one such disease where some forms develop in humans consuming certain diets. Such a dietary effect is evident in humans eating a typical Japanese diet that is associated with a high incidence of stomach cancer and low incidence of colon cancer. In contrast, the typical high-fat American diet results in the opposite. The reason for these differences is unknown.
Diet composition can affect mammary tumors. Diets low in methionine protect against tumor appearance and growth. Foods rich in methionine promote tumor appearance and growth.7 Chemicals in some diets are toxic and over time can cause diseases such as cancer. High dietary nitrosamine, for example, causes acute hepatic necrosis and chronic ingestion of lower amounts causes hepatic cancer. Some microorganisms produce dietary chemicals, such as aflatoxin produced by a fungus, that cause hepatic necrosis. Normal dietary constituents can be toxic and naturally occurring protectants minimize or prevent damage. Antioxidants protect against free radicals which appear as oxygen is used to produce energy. Antioxidants are important as dietary unsaturated fatty acids increase. These protectants include naturally occurring nutrients such as vitamin A, Vitamin C, and vitamin E. In addition, commerciallyprepared foods contain synthetic antioxidants such as butylated hydroxytoluene, butylated hydroxyanisole, and ethoxyquin. Vitamin E is essential for cell membrane protection against the many chemical reactions generating free radicals. Vitamin E is more potent than synthetic antioxidants because it binds cell membranes. To be as effective, synthetic antioxidants must be given continuously and in large amounts compared with vitamin E. Membrane bound vitamin E loses its antioxidant activity on neutralizing free radicals, but other antioxidants such as vitamin C can restore membrane vitamin E antioxidant activity. Vitamin E appears to lengthen life span. When animals are given vitamin E from a young age, the onset slows for some age-related problems such as cataracts, cancer, cardiovascular disease, and decreased immune function. High blood vitamin E levels may lower the risk of some cancers. This effect can be due to vitamin E blocking the formation of carcinogens (such as nitrosamines from nitrates in the diet), inhibiting carcinogens from reaching cells, suppressing the effects of cancer and stimulating the immune system. 

Phytochemicals As Protectants
Phytochemicals are the source of nearly all phenolics found in animals. The important phytochemicals are phenolics. Phenolics essential for animals such as tyrosine come either directly from plants or are modified from essential plant precursors. Phenolic phytochemicals are grouped into flavonoids (such as anthocyanins, genistein and daidzein), tannins, lignans, and simple phenols such as the benzoic and cinnamic acids. These chemicals protect plants and have beneficial effects in animals. They protect animal cells by chelating, quenching free radicals, which provides antioxidant activity. Phytochemicals are found in fruits, vegetables, grains and legumes; a human consumes about 25 to 35 milligrams daily.

Soybean products are rich in flavonoids. Other beans are also rich in phytochemicals. In addition, natural blue, purple, red, orange and yellow foods are abundant in flavonoids. The benefits of flavonoids can be lost with food processing. Phytochemicals’ benefits can be enhanced by feeding substances that reduce intestinal absorption of toxins; such substances include soluble fiber. Flavonoids help control cancer growth. The flavonoid genistein prevents malignant angiogenesis, blood vessel development that promotes cancer growth. Genistein also promotes leukemia cell differentiation so they revert to normal cells. Some phytochemicals are toxic to intestinal bacteria. Reducing this bacterial population decreases toxin formation and absorption. Phytochemicals are beneficial only from dietary levels in naturally occurring foods. Excess phytochemicals can be toxic. Phenol-based compounds can be toxic; metabolism of any phenolic chemical releases phenol which is toxic. Owner-prepared diets should be formulated with a natural source of phytochemicals. Their beneficial effects for detoxification and protection should be lifelong.

Feeding to Reduce Cancer
The incidence of tumors is lower than expected in animals fed soy protein diets.7 Several soy protein constituents can inhibit tumor growth. They include isoflavones, phytosterols, protease inhibitors, inositol hexaphosphate, and saponins. Soy proteins are also deficient in methionine. Dietary soy protein instead of animal protein is associated with a lower incidence of breast and colon cancer in humans. No long term studies have been done in dogs and cats but the probability is great that feeding soy protein could have the same effects. A number of forms of soy protein are available. Many diets in this website are based on using one form, tofu, as the primary source of protein.

Feeding to Prevent Cancer Cachexia5,8
Weight loss and cachexia are important complications of cancer. Cancer patients that maintain normal weight live longer and have fewer complications during treatment with chemotherapy, radiotherapy and surgery. Tumor cells uncouple metabolism which accelerates wasting and poor use of nutrients. Metabolic abnormalities affect use of carbohydrates, proteins, and fats resulting in many defects in nutrient usage.

Cancer patients are invariably anorectic and have a basal energy requirement that is twice normal, requiring food intake to be greatly increased. High-caloric density diet are fed to increase energy intake. Up to 50 percent of non-protein calories should be fat. High carbohydrate diets should not be fed. To improve anorexia, palatability should be enhanced by using animal fat such as chicken fat, seasonings such as garlic powder, and feeding food warm. No commercial pet foods meet dietary requirements for cancer patients.

Diets for Geriatric Dogs   

The following diets for geriatric dogs contain the highest quality protein and the most easily digested form of starch. Some are high in fat for normal weight animals that have problems maintaining normal weight. Others are low in fat when obesity is an important problem to manage. All these diets can be supplemented with vegetables listed at the beginning of this page. If a pet tolerates other vegetables or fruits ones can be fed that provide natural chemicals that protect against tissue injury and aging. The diets are relatively low in vitamin and mineral content. Their requirements are met but excesses are avoided because that can be an important cause of tissue injury in older animals. Vitamin E can be supplemented for further protection. Feeding recommendations are based on the diet providing 80 percent of the caloric requirements of a younger dog of the given weight.
