Countless dog owners have witnessed the benefits of feeding their dogs a home-prepared diet, such as cleaner teeth, brighter eyes, thicker and glossier coats, more lean muscle and less body fat, and better energy level -- hyper dogs often become calmer, while couch potatoes may become more energetic.
In last month’s article, “Have Dinner In,” we discussed those benefits at length and introduced the fact that there are many different styles of homemade diets. In this article, we’ll explain how to formulate a raw diet that includes bones – perhaps the most commonly used “evolutionary” diet for dogs. In the next article, we’ll discuss cooked diets.
When I first began to consider feeding my dogs a homemade diet, one of my biggest concerns was the fact that I am not comfortable in the kitchen. I don’t really cook for myself, so the thought of preparing meals for my dogs was overwhelming. Once I started, though, I was happy to discover that it was not as much trouble as I had feared – in fact, it was quite rewarding. Dogs are usually so appreciative of everything we offer that it makes meal time a real joy. I feed a great deal of variety, yet my dog Piglet tells me that each and every meal I put in front of her is her absolute favorite, and she devours it, practically licking the finish off the bowl (I call it “checking for molecules”). How can you resist something that makes your dog so happy?
Most of us who feed a raw diet to our dogs include whole raw meaty bones (RMBs), animal parts that are at least half meat but also include bone that is fully (or mostly) consumed. This is in contrast to recreational bones, such as knuckle and marrow bones, which usually have little meat and where the bone itself is not eaten.
RMBs that are commonly fed include chicken necks, backs, and leg quarters; turkey necks; lamb breast and necks; pork breast (riblets) and necks; and canned fish with bones, such as jack mackerel, pink salmon, and sardines (preferably packed in water rather than oil). Raw fish can also be fed, though some may harbor parasites (freshwater fish are more likely to have problems than saltwater fish). Never feed raw salmon or trout from the Pacific Northwest (California to Alaska), as this can cause a fatal disease called salmon poisoning in dogs. Cooking makes salmon safe to eat; canned fish is cooked, so there’s no concern about salmon poisoning from canned salmon.
Most raw diets are high in fat. Unless your dog is extremely active and has difficulty keeping weight on, it's best to remove skin from poultry, cut off separable fat, and stick to parts that are not overly fatty.
It’s not always easy to find RMBs. If you ask your local meat manager or butcher; they will often be able to order them for you, though you may have to buy a case at a time. (Most of us who feed our dogs a raw diet have purchased a separate freezer to help store their food!) Ethnic markets often have a wider selection than grocery stores do. There are a number of raw food co-ops and groups who share information and buy in quantity directly from vendors, both to lower the cost and to gain access to a wider variety of foods. If there is no group in your area, you might consider starting one.
You can keep costs down by buying in bulk, looking for sales, and buying meat that is close to its expiration date and marked down. It helps to develop a relationship with your suppliers, who may be willing to save bargain-priced meats for you.
RMBs should make up 30 to 50 percent (one third to one half) of the total diet, or possibly a little more if the parts you feed have a great deal more meat than bone (e.g., whole chickens or rabbits). The natural diet of the wolf in the wild contains 15 percent bone or less, based on the amount of edible bone in the large prey they feed upon. While a reasonable amount more won’t harm an adult dog, it’s not needed and reduces the amount of other valuable foods that can be fed.
Too much bone can also cause constipation, and the excess calcium can block the absorption of certain minerals. The stools of raw fed dogs are naturally smaller and harder than those fed commercial foods, and often turn white and crumble to dust after a few days. If the stools come out white and crumbly, or if your dog has to strain to eliminate feces, you should reduce the amount of bone in his diet.
Most dogs do fine with raw meaty bones, but a few may have problems, including choking and (rarely) broken teeth on the hardest bones. In my experience, turkey parts are associated with the most problems, though many dogs eat them regularly with no trouble. Chicken necks can cause choking in small dogs.
If you are concerned about feeding whole RMBs, there are alternatives. You can feed RMBs in ground form, either by purchasing them that way, or by grinding them yourself. You can buy a grinder for around $100 to $150 that can handle most chicken parts and possibly a few other kinds of bones. More expensive grinders may be able to handle bones that are somewhat harder, but they all have a similar chute size, which makes it difficult to fit in larger parts. Note that none of the makers of these grinders claim their products have the ability to grind bones.
Another option that I use for my older dogs, whose teeth are too worn to be able to chew bones properly, is to cut up the parts into bite-sized pieces using Joyce Chen kitchen scissors, which have worked better for me than poultry shears. These scissors handle chicken parts and lamb breast easily (except for the hardest end of the ribs).
For harder bones, such as turkey, pork and lamb bones, you can use a hatchet, or a cleaver that you hit with a mallet (which is safer than swinging the cleaver). While ground and cut up RMBs will not provide the same chewing pleasure or dental benefits, many people who feed ground RMBs report that their dogs’ teeth stay cleaner than when they fed packaged foods, probably due to the lower carbohydrate content of the diet.
You can also feed larger, harder bones with a lot of meat on them; just take the bone away when your dog is done removing the meat. I have done this with beef rib and neck bones; people with large dogs use bigger bones. There is still some danger of broken teeth, but less than if you allow the dog to continue to chew on the bone after he's eaten the meat (bones also dry out and become harder over time).
Remember that if you feed a diet that includes 30 to 50 percent RMBs, there is no need to add calcium supplements.
Heart is nutritionally more like muscle meat than organ meat, but it is rich in taurine and other nutrients. If possible, make heart another 5 to 10 percent of the diet. More can be fed; just remember that too much can lead to loose stools in some dogs. Heart is generally a lean meat, making it a good choice to help keep fat levels down.
Other organs, such as spleen, eyeballs, sweetbreads (pancreas and thymus glands), brain, etc. are nutritious and can be added to the diet in small amounts.
Muscle meat consists of all meat that is not considered organ meat. Feed muscle meat from a variety of sources, such as beef, lamb, pork, chicken, and turkey. Use lean meats, preferably 10% fat or less, and remove skin from poultry unless you are feeding very low-fat breast or your dog is extremely active. Muscle meat can be fed ground or in chunks. If you have difficulty feeding much variety in your raw meaty bones, you can make up for it in this category. For example, if your raw meaty bones are mostly poultry, then you can feed beef, lamb, and pork muscle meat. Never feed more than half the total diet from a single protein source, such as chicken.
Eggs are an excellent source of nutrition. They can be fed raw or cooked; cooking actually makes the whites more digestible. You can feed as many eggs as you want, as long as you still feed lots of variety.
Dairy products, such as yogurt, kefir, and cottage cheese, are well tolerated by most dogs and offer good nutritional value. Yogurt with added probiotics and kefir, another cultured milk product, have the added advantage of providing beneficial bacteria (probiotics). Dairy fat is a source of medium-chain triglycerides, a form of fat that is easier to digest for dogs with pancreatic disorders and other forms of fat intolerance.
Green tripe, which is the stomach lining from cows and other animals, is an excellent food for dogs, but be warned that it smells awful – at least to us; dogs love it. Nutritionally, it is similar to muscle meat. Green tripe can be purchased only from sources that sell food for dogs; it cannot be sold for human consumption. The tripe that you find in your grocery store has been bleached and treated, and does not provide the same nutritional value as green tripe.
It is also fine to feed healthy leftovers (food you would eat yourself, not the scraps you would throw away) to your dog as long as they are not too great a percentage of the diet – 10 to 20 percent of the diet should be okay.
If you feed veggies, they need to be either cooked or pureed in a food processor, juicer, or blender. Whole, raw veggies are not harmful, but their cell walls are not broken down during digestion so they provide little nutritional value to dogs. Most veggies have few calories, so they should be added on top of the amount of food you feed, rather than calculating them as a percentage of the diet.
Good veggies to feed include broccoli, cauliflower, brussels sprouts, cabbage, all kinds of leafy greens, celery, cucumber, bell peppers, zucchini and other summer squashes, carrots, and more. You can mix up a large batch and then freeze them in ice cube trays or muffin tins for easy meal-sized portions.
Steaming is the best method to cook fresh or frozen veggies. You can add the water used to steam veggies to the meal, as it will contain the minerals that were leached out during cooking. Small amounts of leftover meat juices, drippings, sauces, and gravy will make this into a savory soup.
Some dogs enjoy vegetables, but others refuse to eat them no matter how they’re prepared. If your dog won’t eat vegetables, or if you prefer not to feed them, you may want to add a blend of kelp and alfalfa, or a green food supplement (more on this below).
Fruits such as apples, bananas, papayas, mangoes, berries, and melon can be added to the diet in small amounts. Don’t feed grapes or raisins, which can cause kidney damage in some dogs.
Grains, legumes, and starchy veggies, such as potatoes, sweet potatoes and winter squashes, are a source of inexpensive calories, but don’t provide as much nutritional value to dogs as foods from animal sources do. These starchy foods need to be cooked in order to be properly digested by dogs.
Many health problems can be caused or exacerbated by grains and other starchy carbohydrates. If your dog is overweight or suffers from allergies, arthritis, seizures, chronic ear infections, incontinence, IBD, or other digestive disorders, you may want to try feeding a diet without these foods to see if your dog improves. If you decide to feed them, it’s best if they make up no more than 20 percent of the diet.
Potatoes (not sweet potatoes), tomatoes, peppers (all kinds), and eggplant may aggravate arthritis pain, but are otherwise fine to feed. Grains and starchy veggies may also aggravate arthritis and other forms of inflammation.
- Fish body oil, such as salmon oil, provides beneficial omega-3 fatty acids that help to reduce inflammation and regulate the immune system. Sardines can also be fed to provide these omega-3 fatty acids. However, you must add vitamin E to the dog’s diet whenever you supplement with oils, to prevent the body from being depleted of this vitamin over time.
- Sea blend, green blend, or kelp/alfalfa mixture supplies trace minerals. These are especially good to add if you don’t feed green veggies.
- Organic (unpasteurized) apple cider vinegar provides some trace minerals and may possibly offer other benefits.
- Raw honey has antibacterial properties and offers a variety of nutritional benefits (see "Bee Products have a Special Meaning for Dogs," September 2007).
- Fresh crushed garlic has anti-inflammatory and antibacterial properties, as well as other benefits, and may help to repel fleas. Give no more than one-half of a small clove (one small portion of the bulb) per 20 pounds of body weight daily, as high doses can cause anemia. See Garlic for Dogs - How Much and How Often? for more details.
- Ginger is good for digestion and may help with inflammation.
- Nutritional yeast is an excellent source of B vitamins, along with trace minerals.
- Dark molasses can also be used in small amounts as a source of trace minerals.
Even diets that contains a wide variety of foods in appropriate proportions may be short on certain nutrients, most commonly vitamins D and E, and the minerals zinc, magnesium, potassium, selenium, and possibly iodine. More information on supplements is provided in the article on cooked diets.
Feeding parts is not the same as feeding whole prey. When wolves in the wild eat a deer, they consume almost everything except the stomach contents and some of the hardest bones from the skull and legs. That includes not only the muscle meat, bones, liver, and heart, but the eyes, tongue, brain, blood, intestines, kidneys, lungs, and various other organs. If you are not feeding actual whole prey, you may be missing parts of the diet that include important nutrients.
In addition, whole, large, grass-fed prey such as deer, moose, and bison have different nutrient profiles than animals that are farm-raised, and smaller animals such as chickens. The nutrient content of animals raised in various ways (wild animals, grain-fed animals, animals raised on grass from depleted soils) also varies widely. Even if you feed whole rabbits or chickens, the nutrition will not match that of the large ruminants that our dogs evolved to eat.
While some people swear by prey model diets, I believe that there is no benefit to be gained by leaving healthy foods such as dairy and vegetables out of the diet. The more restrictions you place on a diet and the less variety you feed, the higher the likelihood that something may be missing. I believe that adding foods and supplements not found in the natural diet of the wolf can help our dogs live the longest, healthiest lives possible.
Primal Formulas (not Grinds or Mixes), Steve’s Real Food for Dogs, and Nature’s Variety Instinct Raw Frozen Formulas.
These foods can be used just as you would commercial dry or canned foods, with no need to add anything else (though just as with other commercial diets, it’s best to rotate between different brands and protein sources, and it’s fine to add some fresh food as well). Complete commercial raw diets are generally quite expensive, so they’re usually not an option for those who have large dogs or limited funds.
The second type of commercial raw, frozen diets provide a variety of different parts that can be combined, along with other foods, to create a complete diet. These parts may include meat, bone, organs, and sometimes vegetables, but generally nothing else. Examples of companies that offer these types of diets include Bravo! (who now also offers a complete diet called Bravo Balance), Oma’s Pride, Primal Grinds and Mixes, and an increasing number of small, independent local companies. These are great foods to include in the diet you feed your dogs, but you cannot feed them alone, without adding anything else.
When you compare the ingredients of the complete diets to those of the incomplete blends, you will notice that the complete diets add a number of foods in addition to meat, bone, and organs, including such things as eggs, kefir, tripe, kelp, alfalfa (sprouts or dried), garlic, raw honey, organic apple cider vinegar, ginger, oils (fish, flaxseed, olive, coconut, cod liver), seeds (sprouted or ground), nuts, and a wide variety of fruits and vegetables. They also commonly add specific vitamin and mineral supplements, such as vitamin E, manganese, zinc, iron, and copper, or a natural source of minerals, such as montmorillonite clay. Note that complete diets usually include more muscle and organ meat and less bone than the meat/bone/organ/veggie blends.
If you want to use incomplete blends as the basis for the diet you feed, most often you’ll want to add some additional muscle meat that does not include bone, possibly a bit more organ meat (particularly liver), and a variety of other healthy foods, including eggs, dairy, canned fish with bones, green tripe, healthy leftovers, and some fresh food supplements. Fish oil (or sardines) and vitamin E would also be good additions to the diet. The fewer additional foods that you add, the more important supplements will be.
For example, the Bravo! blends are approximately 10 percent organ meats (equal parts heart, liver, and either kidney or gizzards), 15 percent vegetables, and the rest ground meat and bones. These blends should be used as one half to two thirds of the total diet, with a mixture of the other foods listed above making up the rest of the diet. You can get some of these other foods, including muscle meat and organ meat, from Bravo! or at your grocery store.
Most raw diet products are quite high in fat. Be sure to use mostly low-fat additions when the base of the diet is high in fat (10% fat or more). Possibilities include skinless chicken breast, low-fat or nonfat dairy, and starchy foods, such as sweet potatoes and oatmeal. A small amount of egg and canned fish with bones should also be included for variety, even though they are also higher in fat.
Raw meaty bones should comprise around 30 to 50 percent of the diet -- use the higher percentage only if you are feeding parts with a lot of meat, such as chicken leg quarters, not those that have more bone, such as chicken necks and backs. Be careful if you supplement with cod liver oil or another form of vitamin D. Vitamin D increases the absorption of calcium, so if you feed high amounts of bone and vitamin D, you increase the likelihood that too much calcium will be absorbed. Never add calcium to a diet that includes appropriate amounts of bone.
Remember that high-protein diets will not cause excessive growth or lead to orthopedic problems in puppies. These problems are caused by overfeeding and by improper calcium amounts (either too much or too little). In order to avoid orthopedic problems, keep your puppy lean and slow-growing by limiting the total amount fed.
All homemade diets need to contain a variety of different foods, including different types of meat and raw meaty bones, different parts (especially organs), and different foods, such as eggs and dairy. A lot of people depend on chicken since it's cheap, but if your dog gets nothing but chicken, even if you feed organs along with muscle meat and bone, he will not get all the nourishment that he needs. As a general rule, you should never feed one kind of food as more than half the diet, and preferably less.
When you feed a variety of different foods, every meal does not need to be “complete and balanced.” You should ensure that all of your dog’s nutritional needs are met over a period of a week or two, but that can be done by feeding different foods at different meals, and on different days; you don’t have to combine all the different foods into a single meal. It’s also fine to feed just beef, for example, for a couple of weeks, and then switch to another meat source for the next two weeks.
A raw diet that includes 30 to 50 percent raw meaty bones will supply the proper amount of calcium; there is no need to add more.
Most raw feeders can empathize with my friend, Mindy Fenton, who says, “The first time I fed one of my dogs a raw chicken wing, I followed her around for three days, terrified that I was going to kill her, and waiting for that darned wing to come out whole because I was sure it would. Of course, she was perfectly fine, but it took some time before I became relaxed about feeding raw meaty bones.”
The choice of what to start with can vary according to your comfort level, and how likely you think your dogs are to gulp their food. Many people advocate feeding pieces that are too large to be swallowed, requiring the dog to chew on them first. This doesn’t always work, since large pieces become small pieces as the dog eats them, and he may still try to swallow pieces too large to go down easily.
I am most comfortable with feeding chicken necks and backs to my dogs: the bones are soft and easily chewed, and the pieces are small enough to be swallowed even if the dog does not chew them well (small dogs may have problems with chicken necks). Others feed chicken wings or leg quarters. If your dog is not protective of his food, you can try holding onto one end while she chews on the other, to help her learn to chew rather than gulping, but watch your fingers, and don’t try this if it makes your dog anxious.
Many people worry that their dogs may be too old to switch to a raw diet, but in my experience, older dogs do as well as younger ones with the change. My oldest dog was 13 years old when I switched him overnight to a raw diet, and he had no problems.
Most dogs do just fine when switched “cold turkey” from commercial food to a homemade diet, but a few will experience digestive upset from a sudden switch. The longer a dog has been fed the same food with no variation, the more likely he is to have a problem if his diet is changed too quickly. Dogs that are prone to digestive upset may also benefit from a slower, more careful approach.
To make the change gradually, start by adding small amounts of fresh food to the current diet, then gradually increase. If problems develop, return to the prior diet and make the change more carefully once your dog’s digestive system is back to normal. That may include feeding the new food separately from the old (at least a few hours in between meals), or feeding only one new food at a time, to see if your dog reacts to any of the new ingredients.
The one exception to mixing foods is when you feed raw meaty bones. I find that the consumption of kibble interferes with the digestion of bones; digestive problems are more likely if you mix the two together. If you are feeding whole raw meaty bones, feed them separately from kibble, at least a few hours apart.
It’s fine to start with limited variety until you see how your dog does, but don’t feed just one food for long periods of time. Sometimes people will start with just chicken parts, for example, but this may lead to constipation if there is too much bone in the diet. While you may want to feed just chicken at the beginning, be sure to feed plenty of meat as well as bone, and don’t feed such a limited diet for more than a week or two.
If your dog has any problems with the new diet, back up and start again, making the change more slowly this time. Do not blame problems on “detox.” If your dog develops diarrhea or other forms of digestive upset, it is because his diet was changed too quickly, or because he is reacting to one or more of the ingredients in the new diet.
In that case, again, go back to what you were feeding before (or what you know your dog can tolerate without a problem), then add new foods one at a time in order to identify which one(s) are causing problems. Also, while most dogs improve when fed raw foods, a few cannot tolerate it for some reason and may need a cooked diet instead. There will be information on cooked diets in next month’s article.
Most people who switch their dogs to a raw diet notice improvements even in dogs who seemed to be perfectly healthy before. Feeding a homemade diet may cost a little more, but many people report a decline in vet bills. Best of all is watching the enjoyment our dogs get from their meals, and taking pride in knowing we are doing the best we can for our dogs.
Remember that it’s not necessary to feed a balanced diet every day, as long as the diet is balanced over time. For example, it would be fine to feed eggs one day alternating with organ meat the next, rather than feeding both foods every day. Or you might feed just muscle meat one day, with a mix of organ meat, eggs, and dairy the next. Many raw feeders feed two meals a day: one meal of raw meaty bones and one meal of everything else.
Following are sample diets for a 40-pound (18 kg) dog. Remember that amounts will vary depending on the individual dog.
Sample daily raw diet:
- 6 to 8 ounces (175 to 225 grams) raw meaty bones (may include canned fish with bones once or twice a week)
- 4 to 6 ounces (100 to 175 grams) lean muscle meat/heart/tripe/leftovers
- 1 to 2 ounces (30 to 60 grams) liver or kidney
- 1 to 2 eggs (daily or every other day)
- spoonful of yogurt, kefir or cottage cheese
- 1 to 4 ounces (30 to 100 grams) pureed or cooked vegetables (optional)
- 7 to 14 ounces Bravo! Original Formula Blends (may replace up to half with canned fish with bones once or twice a week)
- 2 to 4 ounces lean muscle meat/heart/tripe/leftovers/Bravo! Boneless Meats
- ½ to 1 ounce liver or kidney, or 1 to 2 ounces Bravo! Organs (daily or every other day)
- 1 or 2 eggs (daily or every other day)
- spoonful of yogurt, kefir or cottage cheese
- 1 or 2 fish oil capsules (or 3 small sardines)
- 200 IUs vitamin E (required at least a couple of times a week if giving oils)
- ¼ tsp each kelp and alfalfa, or ¼ to ½ tsp green blend
- 500-1,000 mg vitamin C once or twice a day
- vitamin B-50 complex once or twice a day
- cod liver oil in an amount yielding around 100 to 200 IUs vitamin D
- ½ teaspoon organic apple cider vinegar mixed with ½ teaspoon raw honey
- 1 clove fresh crushed raw garlic
- 1-2 tablespoons nutritional yeast
Many people are concerned about the dangers of bacteria and parasites when feeding raw meat, eggs, and dairy to our dogs. Remember that wolves and dogs evolved to be able to cope with bacteria found in carrion and meat that has been buried for long periods. Their digestive systems are designed to move food through quickly, before bacteria has a chance to proliferate or cause problems. Bacteria such as salmonella are found in the digestive systems of as many as 40 percent of healthy dogs, including those fed only commercial foods. While these bacteria can affect dogs, it would be unusual for a healthy dog to have any problems with the bacteria found in raw meat and other products considered fit for human consumption.
There are a few parasites that might be a cause for concern, though freezing meat for a period of three weeks will destroy most of them (freezing has no effect on bacteria).
You may want to consider feeding a cooked diet to your dog if you’re concerned about the possibility of problems from raw meat, your dog’s immune system is compromised due to illness or medication, or your dog just doesn’t seem to do well on a raw diet. See next month’s article for more information on cooked diets.
