Dog Food for Firm Stools Buyer’s Guide

dog food ingredients for firm stool

The wonderful world of dog food can quickly become a lot less superb when you try to find the right product for your furry pals, as it can easily get confusing! There are so many different ones to choose from, and for the untrained eye, it can be near impossible to separate the good stuff from what is not so great. Due to this, many dogs end up presenting signs of digestive issues, as they are simply not fed what is right for them.

A few dog food products are made to suit pups with rumbling tummies to help them get rid of runny stool, possible vomiting, and stomach aches. You should always talk to your veterinarian to rule out any more serious health issues if your dog has frequent diarrhea (such as a worm infection), but if food is ruled to be the issue – it is time to switch to a better option.

What to Look for When Buying Dog Food for Firm Stools

If you want to look for only the best food for your pup, look for these ingredients to promote a well-conditioned digestive system.

Natural Ingredients

The key to a happy and healthy dog is nutritious dog food made with natural ingredients. Imagine if you, as a dog owner, would eat your breakfast, lunch, and dinner at a fast-food restaurant – all year round! It is the same as if a dog would be fed only a low-quality kibble. Instead, make sure you read the ingredients list and look for real meat products listed first (no animal by-products), followed by natural fruit and vegetables.

Artificial ingredients can and will often irritate sensitive pup stomachs and can contribute to runny stools! Stay away from any artificial color, flavor, and preservatives! As a rule, if the kibble has bright colors like red and green, it is probably caused by an artificial color additive.

Probiotics & Prebiotics

The first thing you need to know is that probiotics and prebiotics are two different things, but they are both beneficial for dog foods that firm up stools. An easy way to put it is that prebiotics takes care of the good bacteria in the dog’s intestines. Prebiotics nourish and “feed” the good bacterias, while probiotics – on the other hand – are the bacteria that prebiotics looks after. Prebiotics are in most cases added to dog food, while probiotics should come naturally from the ingredients.

There is some debate on whether prebiotics is genuinely beneficial for dogs with stomach issues, but probiotics surely are. For us humans, most know that yogurt has probiotics, and perhaps we were told to eat yogurt to stay healthy when we were younger. The same applies to dogs. To ensure your pup’s digestion works as it should – double-check that the dog food you are buying has probiotics to aid the metabolism and protect the intestines.


Going grain-free or sticking with healthy grains is a personal choice, but there are indications that dogs may do better on a diet more closely shaped after what their ancestors ate. Many low-quality dog foods use fillers like corn, wheat, and soy, which aren’t necessarily bad. Still, they also don’t contribute much (if anything) when it comes to nutrition.

Foods that solidify stool are those that provide your fur friend with the nutrition he or she needs. Even though there are quality grain dog foods as well – you might want to stay away from grain just to be on the safe side.

Best dog food for a puppy with loose stools?

A great option for puppies is Natural Balance Limited Ingredient Dry Dog Food – Potato & Duck Formula. They offer both puppy dog food, one for adults, and a small dog breed kibble. This means that you can start your puppy off right with food made for puppies with sensitive stomachs and switch to the adult variety once the time comes. The benefit here is that you won’t have to change brands as the puppy grows older, which can help sensitive doggy stomachs.

Best dog food for a senior dog with diarrhea?

First, you need to rule out any other underlying issues, especially if diarrhea has started seemingly for no reason. Have a talk with your trusted veterinarian. If he or she thinks a new gentler senior dog food is the way to go – consider trying ACANA Singles Limited Ingredient Dry Dog Food. It has a total of 60% lean protein and is made with only natural ingredients. What’s more incredible is that it help firm up your senior pup’s stool while also providing them with the nutrition they need to age with grace.

How to know if it is the right food for my dog?

If your dog continuously struggles with an upset tummy, diarrhea, and loose stools, it is worth considering that you might not be feeding them the right food. It does not have to be about quality, as not all high-quality dog food works for every dog, and it might be more of a question of what is in the food you are feeding.

Try switching to dog food with limited ingredients – preferably natural – and see a difference. Keep in mind that you might not notice a change right away, so give it some time before deeming the food unfit. Also, always consult your veterinarian if the symptoms persist or if you feel concerned.


Dog’s are family too, and we should always look out for our family – furry or not – to make sure they have what they need to feel good physically and mentally. An upset stomach and runny stool are no fun, and dogs (in particular) are very good at hiding signs of discomfort. By providing a quality kibble; made with natural ingredients and lean meat products, you reduce the risk of irritating your pup’s sensitive GI tract.

There is dog food that makes dogs poop less, preventing it from coming out loose. The pet foods mentioned in this article are all high-quality items likely to aid healthy digestion. It’s up to you to figure out which one is the best one for your pup that will agree with them both in flavor and nutrition.

Expert Tip

Avoid feeding your dog table scraps, as food cooked for humans usually contains condiments that are highly likely to irritate the canine stomach. Find the right dog food and stick to it.

Did You Know?

Nature is full of foods to solidify stool, and one of them is a pumpkin! Add some canned pumpkin to your dog’s diet when they suffer from diarrhea or pick a dog food product with pumpkin as one of its ingredients.
