How Long Does it Take a Dog to Digest Food?

  • 8 min read

How dogs digest food is often a mystery for pet owners. We know the process shares some similarities with human digestion, but there are some fascinating differences that make canine digestion unique and intriguing.

In this article, we’ll dive into how a dog's digestive system works and how long it takes for them to digest food. We’ll also share some helpful tips on how you can promote your dog’s digestive health for a happy and healthy life.

Let’s dive in!

How Does a Dog’s Digestive System Work?

Compared to us humans, dogs have a relatively simpler digestive system. Yet it’s a fine-tuned mechanism that allows them to break down and absorb the nutrients from the food they eat.

Below, we have explained the entire step-by-step process of how food travels through a dog's digestive system:

Getting In

The digestion process starts from the mouth when your dog eats the food. Their 42 large and sharp teeth (28 in the case of a puppy) help them to bite and tear up every kind of food, including kibble, meat, and bones. Their strong jaws that move up and down (not side to side) also play a significant role in initiating the breakdown process.

Also, dogs don’t produce saliva to break down carbohydrates in foods. Instead, their salvia only helps lubricate the food, making it easier to swallow and pass through the esophagus toward the stomach.

Reaching the First Stop: Stomach 

Once the food reaches your dog’s stomach, it breaks down into smaller particles and mixes with gastric juices. The purpose of this process is to make it easier for the body to absorb nutrients from the food.

However, the actual absorption of nutrients does not occur in the stomach. It’s just the place where solid food gets converted into a mushy semi-liquid substance. This substance is gradually released from the stomach into the small intestine, where all the nutritional benefits from the food take place.

Please note that sometimes, the food that has already gone down can unexpectedly come back up. It’s quite common in dogs, especially those who eat kibble. This happens when they gobble down their food too quickly and they swallow a lot of air along with the kibble. It causes their stomach to expand, and this condition is commonly known as kibble bloating. 

Passing through the Small Intestines

As the food starts moving through the small intestine, various nutrients, vitamins, and minerals from the food are absorbed through the walls of the small intestine and then transported into the bloodstream. From there, these nutrients are transported and distributed throughout a dog’s body.

Arriving at the Final Stop: Large Intestines

The remaining indigestible materials, such as insoluble fiber and some waste products, continue their journey from the small intestine to the large intestine, also known as the colon. This is the place where the water and electrolytes are absorbed, and the fiber is fermented by beneficial gut bacteria. Once all the water is reclaimed, it solidifies and becomes feces.

However, when you’re feeding your dog raw food and vegetables, you might see parts of those in your dog’s stool. This implies that the dog’s body has absorbed the nutrients from the food, and the non-digestible fiber has exited their body.

Getting Out

Feces get stored in a dog’s rectum until it’s ready to be expelled from the body. This happens when the rectum gets full, triggering the contraction of its muscles and pushing the waste out through the anus.

Most vets recommend monitoring the dog’s feces, such as its consistency, color, and frequency, to understand if there are any potential issues with the dog’s digestive health. A healthy digestive system will produce firm and well-formed feces. In case there’s some problem with their health, you may notice changes in the color or texture of the feces, for example, it could either be too loose or too hard.

How Long Does it Take a Dog to Digest Food?

Ideally, the entire process of digestion takes between 8 to 10 hours. For smaller or younger dogs, it may take 4 hours to digest, while larger dogs may need up to 12 hours.

This digestion process significantly influences a dog's overall health and well-being. During this time, their body is absorbing all of the essential and available nutrients found within the food they eat.

However, the digestion timeline can vary depending on various factors, including:

Type of Food

Different types of foods have different digestibility; for example, raw meat takes less time to digest than highly processed dog food, such as extruded kibble. It’s because the processing and cooking methods can affect the time it takes for the gut and digestive system to break down the food and absorb the nutrients.

Please note that the faster digestibility of raw meat doesn’t make it a “better” option. The quality of the diet and food safety are also important factors to consider when deciding on the best diet for your dog.

Size & Breed

Both the size and breed of a dog can influence their digestion time. It’s mainly because large breed dogs have a larger digestive tract, which means the food has to travel for a longer period of time before being converted into feces. Smaller breed dogs, on the other hand, have shorter digestive tracts and, therefore, take less time to digest their food.

Activity Level

Dogs that are more active and engage more in physical exercises tend to have faster digestion compared to less active dogs. It’s because physical activity helps stimulate the blood flow to the digestive organs, making them work more quickly and effectively.

Health & Medication

Any underlying health issues, especially gastrointestinal disorders, can significantly impact a dog's digestion time. Additionally, medications prescribed to your dog can also have an effect on their digestion.

If you are noticing sudden changes in your dog’s digestive timing or the quality of their stool, like they are pooping more frequently, then you should consult with a veterinarian to discuss this further.


If you’re a new pet parent, you might wonder how long does it take a puppy to digest food. Is it similar to an adult dog? The answer is no! Puppies have a higher metabolism, which results in quicker digestion and nutrient absorption. Thus, their typical digestion time lies somewhere between 4-5 hours, and that’s why most vets suggest feeding a puppy more frequently than an adult dog. But again, this time can vary depending on their breed and health conditions.

Stress Level

Stress, brought on due to any reason, can affect your dog’s digestive function. It leads to reduced blood flow to the gastrointestinal tract, which slows down the passage of food, or it can disrupt their gut biome, leading to an imbalance of the good and bad gut bacteria, impacting digestion and nutrient absorption.

Apart from that, stress can also indirectly affect your dog’s digestive system by decreasing their appetite, leading to less food intake and delayed digestion.

Hydration Level

Your dog's water intake is another crucial factor that influences their digestion time. When their water intake decreases, the blood flow to their GI tract also decreases. This slows down the transit of the food, resulting in delayed digestion.

Whereas drinking enough water helps keep the digestive tract lubricated, which assists in the smooth transit of food through the digestive system. It also promotes nutrient absorption and helps in the formation of firmer stool that is easier to pass during defecation.

How to Promote Healthy Digestion in Dogs

While you cannot prevent some occasional digestive issues, you can take certain steps to promote healthy digestion in dogs. Here are 8 simple yet effective tips you can follow to get started:

1. Give them a well-balanced diet

You should provide your dog with a high-quality diet that contains all essential nutrients, including protein, carbohydrates, fats, fiber, vitamins, and minerals. Plus, their food should be free from harmful chemicals, artificial sugars, and fillers, as these can negatively impact their health and digestion. 

2. Regular exercise

Being physically active not only supports a dog's digestive function but also promotes their overall health. That’s why it’s recommended that you incorporate various activities like walking and playdates into their schedule to keep them healthy and active.

However, be mindful of your dog’s age and health condition while planning their exercise routine.

3. Monitor water intake

Proper hydration in dogs is linked with better nutrient absorption, smoother bowel movements, and reduced risk of constipation. Thus, you should ensure your dog has access to proper, clean, and fresh drinking water at all times.

If your dog is fussy about drinking water, you can give them ice chips, frozen treats, or water-rich fruits like watermelon. But if they are too reluctant to drink, you should consult with a veterinarian to ensure they don’t have any underlying health issues.

4. Keep them stress-free

Stress has a significant impact on a dog's digestive system. It can reduce their appetite, cause irregular bowel movements, and even lead to health conditions like IBD. That’s why, apart from your dog’s physical health, you should invest in their mental health.

You can try positive reinforcement training, spend quality time with them, provide socializing opportunities, and, most importantly, create a safe and comfortable environment for them to grow and thrive.

5. Avoid feeding them table scraps

This is a common problem in homes with pets. Dogs often beg for table scraps during mealtime, and it can be hard to resist their pleading eyes, but this can cause more harm than good.

In fact, table scraps can often contain or come in contact with ingredients like spices, onions, garlic, or certain artificial sweeteners that are toxic for dogs. These ingredients can cause a range of health problems, including various digestive issues.

6. Avoid overfeeding

You should always feed your dog the right amount of food based on their specific dietary needs, age, size, activity level, and any health concerns. If you aren’t careful, you can easily go overboard with their portion sizes and overwhelm their digestive system, which will eventually lead to issues like bloating, indigestion, and obesity.

7. Give them prebiotics and probiotics

Probiotics are the live beneficial bacteria present in your dog’s gut, and prebiotics are non-digestible fibers that serve as food for probiotics. Together, they can provide many benefits for your dog's digestive health by maintaining a healthy gut environment, improving nutrient absorption, and boosting the immune system.

You can opt for natural probiotic and prebiotic supplements like plain yogurt and chicory roots, or you can consult with your veterinarian about the right commercial supplement for your dog.

8. Schedule regular veterinary check-ups

Taking your dog for veterinary check-ups can help in maintaining their digestive health and overall wellness. You can use these visits to address any concerns you might have regarding your dog’s digestion and get personalized dietary recommendations.

Furthermore, regular vet visits can help detect any digestive issues at early stages and prevent further health complications.

Summing Up

There you have it - a comprehensive overview of how long it takes a dog to digest food. It might be overwhelming to understand everything at once, but you can gradually familiarize yourself with the various stages and processes of their digestion. This knowledge will help you promote their digestive health and prevent various health complications that can affect the overall quality of their life.
