Feeding Raw and Gently Cooked: Should You Mix Them in the Same Bowl?
By Kelly Gredner, RVT, VTS (Nutrition) ·
Can you mix raw and cooked dog food in the same bowl? It's one of the most debated questions in the canine nutrition community, and the honest answer is more nuanced than a simple yes or no.
Currently, the concerns are usually rooted in digestion rates; the idea that raw food, kibble, and gently-cooked foods are all digested at different speeds, potentially causing a "traffic jam" in your dog's intestinal tract that could result in poorer digestion overall, tummy upset, and stinky poops!
As we learn more about canine nutrition, is this a recommendation founded in hard science, or is it just a precaution? Here is what we know about mixing different dog food formats, and how you can make the best choice for your dog.
What Are Raw Diets for Dogs
Raw diets for dogs consist primarily of raw animal proteins and bones, with a low inclusion of vegetables, fruit or grains compared to conventional diets.
These diets have a focus on whole foods with very minimal to no processing. In general, these types of foods are higher in protein and fat and lower in carbohydrates, including fiber, than conventional diets for dogs.
What Are Gently-Cooked Diets for Dogs
Gently-cooked diets usually consist of whole foods like animal proteins, grains, and vegetables that are cooked thoroughly enough to remove potentially harmful pathogens, but not in high enough temperatures to denature proteins, destroy vitamins and minerals, or reduce palatability. They have varying amounts of protein, fat, and carbohydrates and usually include a high amount of fiber.
Can You Mix Raw and Cooked Dog Food Without Digestive Issues
So, can you mix raw and cooked dog food without it causing digestive issues? The major theory on why we shouldn't mix food formats is based on the idea that they require vastly different digestive environments. And it's true! Fat content, fiber, meal size, food processing, and moisture content can all affect how quickly food leaves the stomach and is digested in the intestinal tract. That said, the canine gastrointestinal tract is quite remarkable.
There is no strong scientific evidence yet that suggests that a healthy dog's digestive system cannot process high-quality raw proteins alongside high-quality gently cooked proteins in the same meal.
The Real Conversation: Digestion and Digestibility of Dog Food
The gastrointestinal system processes food from the mouth to the anus, with transit times for dogs ranging from 6 to 48 hours¹. This duration is influenced by several factors:
Dietary Factors That Affect Digestion
Dietary Factors: Fat levels, fiber content, food digestibility, meal size, and hydration/moisture all impact how quickly food moves through the digestive tract.
Physiological and External Factors
Physiological & External Factors: A dog's age, breed, size, activity level, and any underlying gastrointestinal diseases play a role in digestive speed and efficiency.
Additionally, dogs generally do not require supplemental enzymes unless they have a medical condition like Exocrine Pancreatic Insufficiency (EPI), as the body naturally produces the necessary enzymes to break down food.

Digestion vs Digestibility in Dog Food
What's the Difference Between Digestion and Digestibility
When it comes to digestion, terms like "easy/hard to digest" or "makes the body work harder" are commonly used. These may be marketing terms but what they are actually referring to is digestion and/or digestibility.
Digestion²: A combination of mechanical and chemical processes that breakdown food into smaller, easily absorbable components. Digestibility²: The percentage of nutrients that can be broken down into absorbable molecules in the digestive tract
A food or ingredient with low digestibility means less nutrients are absorbed to be utilized by the body and therefore more waste is produced (bigger poops)! A food or ingredient with high digestibility means more nutrients are absorbed to be utilized by the body with less waste produced (smaller poops)!
Digestibility is also impacted by multiple factors like:
- Food form (cooked, raw, purified)
- Food type (fat, protein, carbohydrates)
- Fiber quantity and type (soluble, insoluble)
- Processing methods (low heat, high heat, steamed, boiled, uncooked, etc)
More Factors to Consider When Mixing Raw and Gently Cooked Dog Food
Not all raw or cooked dog foods are created equal. Other factors of concern when deciding on whether to feed two different types of pet food are.
Bioavailability of Nutrients
The bioavailability of nutrients, or the amount of those nutrients that are absorbed and can be utilized by the body. This can also be affected by the quality of the ingredients and the processing method. Although raw proteins are often praised, gentle cooking can actually enhance the digestibility and availability of certain starches and proteins, making them more available to your dog.
Impact on the Microbiome
How the food type affects the microbiome because the microbiome ferments some of the food which creates digestible and absorbable nutrients. Foods that provide a diverse range of fibers can help promote a diverse microbiome which then helps to maintain a robust immune system and healthy digestion.
Impact on Micronutrients
The impact on micronutrients and their effect on important ratios in the body (like calcium and phosphorus).
Complete and Balanced Nutrition
Complete and balanced nutrition is required for a pet to thrive long term. Gently cooked dog foods usually adhere to AAFCO or NRC feeding guidelines, therefore essential nutrients are maintained throughout the meal. Unless you are buying a pre-made, balanced diet from a raw food manufacturer, there is a risk that your dog will experience vitamin/mineral deficiencies or excesses.
Calorie Intake
Calorie intake is also impacted by food format. Home prepared meals like raw diets can sometimes contain unknown calorie amounts, which can lead to over or underfeeding, both of which are concerning. Whereas a gently cooked meal will have easily identifiable calorie information on the packaging. No guesswork required!
The Safety Factor of Mixing Raw and Cooked Dog Food
One of the most important considerations is pathogen control. Raw diets carry a natural risk of bacteria (such as Salmonella or E. coli)³. Gently-cooked diets, when prepared correctly, utilize heat to significantly reduce these pathogen loads while preserving the integrity of vitamins, minerals, and proteins. When mixing formats, the safety standard of the entire bowl is affected.
From "Rules" to "Tolerance": How to Approach Mixed Feeding for Dogs
The decision to mix feeding formats isn't about following an arbitrary rule, it's about knowing your dog.
Every dog is an individual with a unique metabolism, history, and sensitivity level. For some dogs, mixing raw and gently cooked provides the best of both worlds. For others, a single format might work better for their individual system.
How to Get Started
- Start Slow: If you decide to introduce a mix, do it gradually. Introduce one new food format in small amounts to monitor how your dog responds.
- Watch the Stool: Your dog's stool is the best indicator of digestibility. Consistent, firm, and manageable stool is the gold standard. If you notice persistent loose stool (or a gassy pup!), it may indicate that the combination isn't agreeing with them, or that the ratio of fiber/fat needs adjustment.
- Focus on Quality: Whether you choose raw, gently cooked, or a mix, prioritize Human Grade, high-quality ingredients.
At the end of the day, there is no "one size fits all" approach to canine nutrition. By focusing on your pet's unique tolerance and keeping an eye on their overall health and stool quality, you can find a feeding strategy that works for both of you.
So, can you mix raw and cooked dog food? For most healthy dogs, yes, as long as you introduce it thoughtfully and pay attention to how your individual dog responds.
