When preparing a raw food diet for dogs (often referred to as BARF, or Biologically Appropriate Raw Food), you assemble your dog's meals yourself using raw meat, offal, raw meaty bones, pureed vegetables, fruit, and oils. When done correctly, this feeding method provides maximum transparency and lets you tailor meals precisely to food sensitivities. However, calculation errors or inadequate hygiene pose serious risks of nutritional deficiencies and infections.
| Criterion | Details on Raw Feeding |

Raw Feeding for Dogs: What Does It Actually Mean?
The acronym BARF originally stood for "Born-Again Raw Feeders" and was later reinterpreted as "Bones And Raw Food" or "Biologically Appropriate Raw Food". When you choose raw feeding for your dog, you forgo commercially processed kibble or wet food in favor of fresh, uncooked ingredients.
This dietary philosophy is rooted in mimicking the natural prey model of wild canids. Even though wolves and dogs are closely related, domestication has left clear genetic traces: domestic dogs can digest starches far more effectively than wolves thanks to specific dietary adaptations—a result of thousands of years living alongside humans. Even so, as carnivores, dogs possess a digestive system that efficiently breaks down and utilizes high-quality animal proteins and fats.
Benefits and Risks of Raw Feeding in Dogs
The raw feeding debate among pet owners is often highly charged. From a scientific and veterinary perspective, there are distinct potential advantages, but also significant, well-documented risks.
Benefits of a Raw Diet
- Total ingredient control: You know to the gram what ends up in your dog's bowl. Artificial preservatives, fillers, and undeclared animal by-products can be excluded entirely.
- Targeted ingredients for allergies: Preparing rations at home allows you to use novel protein sources. However, an elimination diet should always be supervised by a veterinarian and does not need to be raw—according to the TVT (Veterinary Association for Animal Welfare), the benefits of raw feeding can also be achieved with cooked home-prepared rations.
- Stool quality and palatability: Fresh food rations typically offer high digestibility. This often leads to smaller, firmer stools. Most dogs also show an exceptional appetite for fresh, raw meat.
Risks and Veterinary Concerns
- Chronic malnutrition: According to the Federal Chamber of Veterinarians (BTK), the nutrient profile of every individual component must be carefully calculated and balanced, otherwise deficiencies or toxic oversupplies can occur; a lack of calcium disrupts bone metabolism. The TVT also highlights an improper calcium-to-phosphorus ratio, which can cause permanent skeletal deformities, particularly in puppies.
- Pathogen and parasite contamination: Raw meat can harbor bacteria such as Salmonella, Escherichia coli, or Campylobacter. The Veterinary Association for Animal Welfare (TVT) notes that Salmonella, Listeria, and Campylobacter are relatively common, alongside parasites like tapeworms or Toxoplasma and antibiotic-resistant bacteria. The risk does not stop with the dog: shed pathogens in feces also endanger human household members (zoonotic risk).
- Injuries from bones: Raw bones can splinter, break tooth enamel, become lodged in the throat, or cause life-threatening constipation ("bone fecal impaction") that can lead to bowel obstruction.
- Dangers from hazardous ingredients: Raw pork carries the risk of transmitting Suid herpesvirus 1 (Aujeszky's disease or pseudorabies), which is invariably fatal to dogs; while domestic herds in Germany have been officially free of it since 2003, the BTK still strongly advises against feeding raw pork. Animal windpipes (gullet) and poultry necks frequently contain residual thyroid tissue, which can trigger diet-induced hyperthyroidism when fed regularly.
Balancing a Dog's Raw Diet: The Core Components
According to the TVT, "classic" BARF rations consist of roughly 60–80% meat, 10–30% raw meaty bones, and 10–25% vegetables and fruit, finished with a small amount of plant oil. However, rule-of-thumb ratios are no substitute for an individualized ration calculation. Here is an overview of the key components:
Animal Components (Meat, Offal, Bones)
- Muscle meat: Supplies high-quality protein, essential amino acids, and energy. The ideal fat content depends on your dog's specific energy requirements.
- Green tripe or omasum: Green, unwashed tripe is a staple in raw feeding plans and contains partially digested plant fibers.
- Offal (organ meats): Organs are nutritional powerhouses. Liver is exceptionally rich in vitamin A (and should never be overdosed), while kidney, spleen, heart, and lungs round out the mix; lung is connective-tissue-rich and more difficult to digest.
- Raw meaty bones: Soft bones surrounded by plenty of meat (e.g., poultry carcasses, veal brisket bones) cover calcium and phosphorus requirements. Cooked bones are strictly off-limits, as cooking makes them brittle and prone to dangerous splintering.
Plant Components (Approx. 10–25% of the Total Ration)
- Vegetables (majority of the plant portion): Varieties like zucchini, carrots, cucumber, or fennel deliver secondary plant compounds and dietary fiber that support healthy gut motility. Because dogs cannot break down tough plant cell walls on their own, vegetables must always be pureed finely or gently steamed.
- Fruit (smaller portion): Apples, pears, or berries provide natural vitamins. High-sugar fruits should be used sparingly.
Crucial Supplements
Meat and vegetables alone cannot meet a dog's micronutrient requirements. A balanced raw feeding plan relies on specific supplements:
- Omega-3 fatty acids: Meat from conventionally raised animals generally contains more omega-6 than omega-3 fatty acids; whether and which oil (e.g., fish oil) should be supplemented must be part of your ration calculation.
- Iodine: Muscle meat does not provide enough iodine, so kelp meal (Ascophyllum nodosum) is frequently added. As the TVT notes, this can easily lead to iodine toxicity—the exact dosage must be precisely calculated.
- Vitamin D: Usually supplemented via oily saltwater fish or cod liver oil; however, the TVT warns that excessive amounts of liver and cod liver oil can cause toxic overloads of vitamins A and D.
- Calcium substitutes: If your dog cannot tolerate or does not receive raw meaty bones, bone meal or eggshell powder must be supplemented, tailored precisely to balance the phosphorus content of the ration.
Raw Feeding in Practice: A Safe Start
If you decide to switch your dog to a raw diet, approach the transition in a structured, deliberate manner:
- Get a professional diet plan: Don't rely blindly on generic online calculators. Consult a veterinary practice specializing in pet nutrition. Factors like age, breed, weight, neuter status, and activity level must be calculated accurately. If you're planning to bring a puppy home, the HonestDog Breed Finder can help you evaluate the specific needs of different breeds in advance.
- Choose a gentle transition: Avoid switching overnight. Instead, follow a plan coordinated with your vet. Start with easily digestible proteins (such as lean chicken or beef) along with cooked carrots, and gradually introduce further ingredients like offal and bones over the course of two weeks.
- Maintain strict kitchen hygiene: Store raw pet meat completely separate from human food. Use dedicated cutting boards, bowls, and knives. Clean or swap thawing dishes daily, and wash your hands and all utensils thoroughly with hot, soapy water.
- Schedule routine diet reviews: According to the TVT, a routine raw blood panel offers only limited insight into malnutrition, as many blood parameters only show abnormalities after long periods of dietary imbalance. Having your dog's ration recipe professionally re-evaluated at regular intervals is far more valuable, especially for growing puppies, senior dogs, or those with chronic conditions.
When Is Raw Feeding Not Recommended?
In certain life stages and situations, veterinary professionals strongly advise against raw feeding:
- Households with vulnerable individuals: If young children, pregnant women, elderly individuals, or immunocompromised people live in your home, the TVT advises against raw feeding due to the infection risks.
- Dogs with pre-existing conditions: For dogs with kidney or liver disease, urinary stones, or a weakened immune system, the TVT considers standard raw rations unsuitable due to their high protein and phosphorus levels. In these cases, clinically balanced diets or veterinary prescription foods are necessary.
- Puppies, especially large breeds: The TVT considers standard BARF rations unsuitable for puppies. An excess or deficiency of calcium in growing large-breed puppies, such as the Great Dane, can cause irreversible skeletal damage. Raw feeding for puppies must only ever be undertaken under close veterinary supervision.
Frequently Asked Questions (FAQ)
What does the term BARF mean?
BARF commonly stands for "Biologically Appropriate Raw Food" or "Bones And Raw Food". It describes a feeding method where dog owners feed fresh, uncooked ingredients like raw muscle meat, bones, offal, and pureed vegetables instead of commercially manufactured dry or canned pet foods.
How much food does a dog need per day on a raw diet?
As a general guideline for an adult dog with average activity levels, the TVT suggests feeding approximately 2 to 3% of their body weight per day. For example, a 20 kg dog typically receives between 400 and 600 grams of total food daily, divided between animal and plant components.
What meat should you never feed raw to dogs?
You must strictly avoid raw pork (both domestic pig and wild boar). It can carry the Aujeszky's virus, which causes pseudorabies in dogs and is, according to the BTK, always fatal. Other raw meats can also transmit parasites such as tapeworms or Toxoplasma.
Is meat alone sufficient for a complete canine diet?
No, feeding only muscle meat will inevitably cause severe nutritional deficiencies. Meat is rich in phosphorus but contains almost no calcium, very little sodium, and insufficient amounts of vitamins A and D as well as iodine. A complete and balanced meal always requires offal, bones (or calcium supplements), dietary fiber, and targeted nutrient supplementation.
