To sum it all up…
For dogs, just like humans, health begins in the gut. Good nutrition and digestion are key to longevity, wellbeing, and a strong immune system. The dog digestive system is also how your dog derives nutrition and energy from food and stays hydrated.
Dog sensitive stomachs can happen at any age, with old and small dogs more likely to struggle. How can you make sure your dog’s eating the right diet for them and maintaining the strong digestive system they need to thrive? And when issues with the dog digestive system do crop up, how can you identify and treat the problem?
We’re here to help. Today’s blog is full of practical pointers on how dogs digest food, what upsets dogs’ stomachs, and what you can do to help. Let’s get started…
How long does it take a dog to digest food? Digestion is made up of four processes: digestion, absorption of nutrients, movement through the digestive tract (known as motility) and elimination (going to the toilet). Understanding that process can be helpful when dog digestive issues start to appear.
Dogs start to digest food the minute it enters their mouth. Enzymes in their saliva start to break down certain elements of the food eaten and from there, food travels down to their stomach, where gastric juices break it down further.
The partially digested food then moves to the small intestine, where nutrients are absorbed through the intestinal walls into the bloodstream. Being able to absorb those nutrients properly plays an essential part in dogs’ health and wellbeing. Anything they don’t need then moves into the large intestine, where water and electrolytes are absorbed, and poo is formed.
Overall, it takes around 6-8 hours for the dog digestive system to do its job, and for anything your dog has eaten – minus those all-important nutrients – to be passed out again.
The dog digestive system, when it isn’t working as it should, can present issues in a lot of different ways. Common symptoms you might spot include:
Lots of different things can affect the dog digestive system. Some are harmless and temporary, while others can be severe and even potentially life-threatening. It’s important to understand the difference, so you can get your dog the help they need.
Here are some common dog digestive system issues that aren’t usually too much of a concern:
Sometimes, dog sensitive stomachs can also have more serious causes, and need urgent medical attention. If you think your dog’s struggling with one of the following, always call your vet:
If your dog seems to be having digestive issues, there’s usually no cause for panic. Dogs, like humans, can get a sensitive stomach from time to time and it tends to pass quickly. In these cases, it’s best to feed them something bland and make sure they have plenty of water until their symptoms subside. Even infectious diseases and parasites are quite common and usually easy to treat with the help of your vet, so long as you address them quickly.
However, as we’ve seen, some cases are more serious than others when it comes to the dog digestive system. If your dog is chronically vomiting or passing diarrhoea, has stopped eating, or you notice any major changes to their behaviour (such as incontinence or lack of playfulness), this isn’t normal, and they need expert help.
Frequent dog diarrhoea can cause dehydration and in some extreme cases, shock. Contact your vet as soon as you can so they can treat the underlying reason and, if needed, run diagnostic tests. When in doubt, it’s always good to play it safe and rule out serious issues for your own peace of mind.
You can read our blog on toxic plants, foods and household dangers here, but a quick round-up of toxic ingredients includes: raisins and grapes, many types of nuts, chocolate, tea and coffee, some fruit, garlic and onions, alcohol and caffeine. Other ingredients that often don’t agree with dogs are potatoes, avocados, and cheese. Non-toxic ingredients that may cause digestive upset include high-fibre foods, bread, grains and certain types of meat and veg.
Talk to your vet so they can recommend the best treatment plan for your dog. They may run tests, such as taking a blood or stool sample. Usually your dog will be fine, but in some cases, your vet will prescribe tablets such as antibiotics or medication to reduce bloating, or they might recommend you give your dog electrolytes to make sure they stay hydrated.
You might also need to make some changes to their diet. Generally, it’s good to make sure their food is high quality, rich in nutrients and easily digestible, with few filler or artificial ingredients. They’re principles we’re proud to use in all our Natures Menu recipes.
If you ask us, raw food is a natural, healthy choice for your dog, and making the switch is easier than you might think. In fact, you can read our blog on how to transition your dog here.
But whatever changes you’re making to your dog’s diet – whether you’re going raw or not – we always recommend a 7-day transition period. Divide your dog's daily dinner ration into two portions: one new food and their usual food. Feed each portion ideally 12 hours apart. By day 8 you’ll be able to switch the dog to 100% of the new food. We’ve got a whole advice centre dedicated to raw feeding advice, including transitioning your dog’s food.
Always seek urgent attention from your vet if you notice dog diarrhoea for more than 24 hours (or 12 hours if they’re very young or old), or if you notice them struggling to stand or wobbling. Other causes for concern are blood in their vomit or poo, or if they can’t keep anything down.
A swollen, hard abdomen could be a sign of bloat. Other signs include your dog finding it difficult to settle and retching without producing any vomit. This is a life-threatening condition that can kill a dog in hours, so call your vet immediately.
For digestive care, dog food with proteins like turkey, chicken, or white fish is what we’d suggest. They’re easily digestible and can be gentle on your dog’s stomach during times of stress.
At Natures Menu, we’ve got a range of cooked cans and pouches which can be useful when your dog needs a bland, but nutritious and tasty diet. Our Original Chicken with Vegetables pouch could be a great starting point before weaning your dog back over to their normal food.
Usually, pet parents will notice straight away when fresh blood is being passed in their dog’s poo. This tends to come from the lower or last part of the digestive tract, such as the large colon or anus, and appears as spots or strands that are usually bright red. If this happens, call your vet for advice. Blood passed down from further back in the dog digestive system, such as from the small intestine or stomach, will look partially digested and have a darker, more black appearance. Again, this might appear as spots or strands in your dog’s poo, or even seem to make up most of their poo. This can be more serious, so see your vet as soon as you can.
Many dogs have a bout of diarrhoea just once or twice in a day and then go straight back to normal. Providing your dog is acting, eating, and drinking normally, there’s usually no need to panic. However, if the dog diarrhoea persists or they appear lethargic, in discomfort or have stopped eating, it’s a good idea to make a vet appointment.
For dogs and humans alike, immunity starts in the gut. Diet is key to a healthy, happy life for your dog and good nutrition is essential for preventing conditions like diabetes and obesity. It can also help to keep their digestive system healthy, strong, and working properly.
While digestive conditions in dogs are quite common and often easy to treat, think of them as an indicator of your dog’s overall health. For that reason, keeping an eye on their appetite and poo is always important. When in doubt, contact your vet, as certain dog digestive system issues can be a medical emergency or point to an underlying health issue.
