You don't need to put any "oil" , salt nor sugar for dog food's cooking. Receipes are as follows:
Cooking for dogs are intended to get you started, to supplement a commercial diet or to suffice until you can obtain more information or a book on the subject. They have not been balanced for long-term use.
You can use“mix-and-match” diets. Select one ingredient from each category (protein, starch if applicable), and add up to one cup of puréed raw or lightly steamed vegetables (up to three or four at a time of the following: broccoli, squash, sweet potato, cabbage, peas, carrots, green beans, cauliflower, brussels sprouts, kale). Ingredients may also be split, 1/2 of one plus 1/2 of another from the same category. Use organically-raised meat sources whenever possible to minimize antibiotic and hormone residues; this is required if feeding liver. The importance of variety cannot be overstressed. (This applies to any and all diets and recipes!) Do not get in the habit of feeding just one or two combinations of ingredients. Pay attention to your animal companion’s health: his weight, activity level, skin and coat quality. If these are not maintaining or improving, consult your veterinarian about changing elements of the diet.
To make a large batch of food, mix protein source, starch source (if applicable), oil, vegetables, and calcium together. Freeze in meal-sized portions. The other supplements should be added fresh at each meal.
The vitamin-mineral supplement should be a good quality, human-type supplement. Some of the cheaper human supplements, particularly those with a heavy coating, are not well digested by people and will not be by animals. To check, submerge a tablet in a glass of water with a splash of vinegar in it. (This mimics the acid environment of the stomach.) The tablet should dissolve within about 20 minutes. The average human supplement is designed for a 150-pound adult. A cat should get about 1/6 to 1/10 of a human supplement. A dog dosage can be calculated from the weight of the dog compared to 150 pounds. Do not overdose! Some vitamins and many minerals are toxic at high doses.
Alternatively, you can use a specially made dog or cat vitamin supplement, such as Pet Tabs or Nu-Cat. There are many good animal supplements available today that can be found at your local feed store or health food store.
Many supplements from the health food store require that a human take 4-6 tablets a day; a single tablet might be perfect for a smaller animal’s daily needs. You can grind up the supplements with a coffee grinder or mortar and pestle to add to the food; or get one that comes in capsules, and open the capsule to empty the powder into the food.
Bone meal must be an edible, human grade. Do not use bone meal intended for gardening or plants.
Probiotics include acidophilus and other “good” bacteria. They help maintain your companion animal’s normal bacterial population and prevent colonization by disease-causing bacteria. Digestive enzymes are important to keep the pancreas from being overworked, and to aid digestion so your animal companion gets the greatest benefit from the food she eats.
Meat may be fed cooked or raw. (While many holistic veterinarians recommend feeding raw meat, there are potential risks to your companion animal’s health from bacterially contaminated meat. Please discuss this issue with your veterinarian before feeding raw meat.) If feeding raw, it is recommended that meat be frozen for 72 hours at -4 degrees F prior to use. Most meats can be refrozen one time safely, so once you mix the meal, it can be put back in the freezer until thawed for feeding. Always follow standard safe meat handling procedures.
