If you are thinking about switching your dog to a raw diet, you have probably heard it is the healthier way to feed. Owners who feed raw often say so, and studies that went looking for a health advantage have not found one. There is no evidence that raw meat diets are healthier than a balanced cooked or commercial diet, while the risks from germs, unbalanced recipes, and bones are well documented. I would not make the switch. What follows sets each claim made for raw feeding beside what has actually been measured. If the wider food question is still open, how to choose dog food covers it.
What Owners See and What the Research Found
The appeal is easy to understand. Raw food looks less processed and feels closer to what a wild dog would eat, and many owners report a glossier coat or smaller, firmer stools after switching. I do not doubt what they see. A nicer coat or a tidier stool is an observation, though, and an observation is not the same thing as better health. Nobody has shown that raw-fed dogs live longer or get sick less often.
Very few long-term trials compare raw and cooked diets side by side. A 2025 review of the raw feeding research found some studies reporting better stool quality, higher digestibility, stable body weight, and shifts in gut bacteria, which reads at first like the owners were right. The same review explains why that support is thin. The studies were small, the raw and cooked diets often used different ingredients, and some of the bacteria that increased are ones usually considered unhelpful. Its conclusion was that most of the health claims owners make for raw diets have not been backed by research.
What Testing Found in the Food
The evidence for harm is firmer, and it begins with what is in the food before the dog ever eats it. When the FDA tested raw pet foods bought online, 15 of 196 samples carried Salmonella and 32 carried Listeria monocytogenes. Almost none of the dry and semi-moist foods tested in the same project came back positive. That is the comparison worth holding on to, because it is not raw against some theoretical ideal. It is raw against the bag sitting next to it on the shelf.
A dog can get sick from contaminated raw food, but the bigger worry is often the people around the dog. Dogs can shed Salmonella without showing any signs, so a dog that looks perfectly healthy can still spread germs through its stool, its bowl, and the kitchen surfaces where the food was prepared. Nothing about the dog tells you whether that is happening.
Some people face a higher risk of severe food poisoning: children under 5, adults 65 or older, pregnant women, and anyone with a weakened immune system. If someone like that lives in your home, I would not feed raw at all.
What Analysis Found in the Recipe
Germs are the half of the problem that gets the headlines. The recipe is the other half, and it is the half an owner has almost no way of seeing. Raw diets analyzed in studies have shown calcium to phosphorus imbalances and shortfalls in vitamin D and some minerals, and most published home-made recipes are not complete and balanced, even ones written by veterinarians. The recipes that failed were not careless posts on a forum. They were published ones.
Puppies pay the highest price for a recipe that misses, because an unbalanced diet during growth can cause painful skeletal disorders and fractures. A growing dog is better served by a puppy food made for healthy growth. Any home-made recipe also has to steer clear of foods toxic to dogs.
Bones and the Natural Toothbrush Claim
Raw bones are sold as natural toothbrushes, but feeding bones does not reduce plaque or prevent tooth loss from gum disease. The related belief that raw bones are safer than cooked ones has no research behind it either.
Bones can cause broken teeth, blockages in the throat or gut, and constipation. So you would be taking a real risk for a benefit nobody has shown, which is a poor trade. If your dog loves to chew, a safer chew toy does the same job with less risk. For the teeth themselves, daily brushing is the proven home-care route, and a no-chew option such as a dissolving dental strip carries no broken-tooth risk. Ask your veterinarian before offering any bone.
Where the Veterinary Bodies Land, and How to Lower the Risk
The major veterinary and public health bodies have looked at this evidence and landed in the same place. AAHA does not endorse raw or dehydrated foods that have not been sterilized, treats included. The AVMA discourages feeding any raw or undercooked animal protein to dogs and cats and supports diets that have been cooked or pasteurized. Its list of pathogens now includes highly pathogenic avian influenza alongside Salmonella, E. coli, and Listeria. The CDC does not recommend raw pet food or treats at all.
None of that is a judgment on owners who feed raw. The policies exist to prevent infections and nutrient problems, and plenty of thoughtful people read the same evidence and still decide to go ahead. If that is where you land, the risk can be lowered, though it cannot be removed. For a home-made diet, have a board-certified veterinary nutritionist write the recipe and review it every year, because owners tend to drift from the original recipe over time. That review fixes nutrient errors. It does nothing about germs.
For a commercial product, look for one treated with high-pressure processing, the best-studied method for cutting pathogen levels. Even then, a pressure-treated label does not mean the food is sterile.
In the kitchen, treat raw pet food the way you would treat raw chicken for your own dinner. Wash your hands with soap and water before and after handling it, and clean every bowl, scoop, and surface it touched. Store it sealed and separate from your own food, thaw it in the refrigerator, and throw away leftovers that have sat out. Freezing, freeze-drying, and dehydrating only reduce the number of germs. They do not kill all of them.
The annual recipe review is also the right moment to ask whether any of the supplements dogs actually need belong in the bowl. Bring the full recipe, including brands and supplements, to your veterinarian and ask for a review of both safety and balance. If your dog develops diarrhea or vomiting on a raw diet, tell your veterinarian exactly what you are feeding, because that one sentence changes what your veterinarian looks for first.
