How Long Does It Take for a Dog to Digest Food?

A key part of owning a dog is monitoring what comes out as much as what goes in. However, many of us don’t spare a second thought for our dog’s digestion, until problems start to occur. Knowing about your dog’s digestion is essential to spotting problems quickly and making sure that your dog is getting everything it needs to stay healthy.

The first thing you need to know is that dogs react differently to food than humans do. Their primary reaction is to eat the food, and not savor the taste. This is demonstrated in the very anatomy of your dog, they have significantly less taste buds than humans do, and more teeth. Due to this, it’s often difficult to keep your dog away from things it certainly shouldn’t be eating.

What Can Influence Digestion Time in Dogs?

No two dogs digest their food in the exact same way, there is a lot at play that can determine how quickly the food is going to travel from the mouth, through the intestines, and eventually be evacuated. Some of the main influencers of the digestion time in dogs, include:

Commonly, you can expect dry dog food to be digested between 8 and 10 hours after it was served. Wet dog food, on the other hand, is generally digested at a much quicker rate, normally in the space of 4 to 6 hours.

If your dog is in poor health, has pre-existing conditions, or is overweight/underweight, then the digestion time could be drastically altered. The key to understanding more about your dog’s personal digestion lies in its waste.

What Can a Dog’s Waste Reveal About Digestion?

Just like with humans, excrement can reveal a lot about your dog’s overall health and any digestion problems. Often, a quick examination of your dog’s waste is all that’s needed to tell you if something is wrong with their digestion.

If your dog isn’t absorbing all the nutrients it needs, then its health could be put at risk. Some of the waste warning signs you should be looking out for, include;

  • Constipation
  • Undigested food in waste
  • Diarrhea
  • Infrequent or too frequent waste
  • Overly large or small waste

If you notice any problems with your dog’s waste, then it could be a big sign that something isn’t right. The frequency that your dog eliminates its waste is also a major indication as to how quickly it’s digesting its food.

Is There Anything That a Dog Can’t Digest?

There are many foods that dogs can’t digest properly, but also foods that they digest very quickly. The enzymes in your dog’s mouth are different to the enzymes in your mouth. This is partly the reason why there is such a variance between how long you take to digest certain food, how long your dog takes to digest certain food, and why not all human food is suitable for dogs.

One of the biggest contrasts between digestion times in dogs is that of corn vs bread. You’ll likely find that corn will appear in your dog’s waste in a matter of hours after it has been consumed, and not appear very digested.

In contrast, dog’s find it incredibly difficult to digest and pass any significant quantity of carbohydrate, such as that in bread – mainly because they don’t have the enzymes that are required to effectively break the carbohydrates down.

Some of the food items that dogs find difficult to digest, or that are poisonous for dogs to digest, include:

  • Dairy Products
  • Some fresh fruit and dried fruit
  • Caffeine
  • Chocolate
  • Garlic
  • Onions

Any of these food items consumed in even a small quality, can seriously impact your dog’s health.
