The Best Dog Food for Loose Stool (Review) in 2021

Last Updated April 28, 2021

Time is of the essence when you’ve got a dog with loose stools. Operation Backyard is afoot as soon as your poor pupper makes the slightest sound that they’re uncomfortable: you’ve only got about a minute until your immaculate carpet is tarnished beyond repair.

In all seriousness, a dog who suffers with loose stools for a few hours is one thing; yet for others, the inability to produce normal stools is routine. Indeed, a whopping 70% of a dog’s immune cells are located in their gut, meaning that if a dog’s gut is in disarray, they don’t have much protection from other diseases. With these poor pups in their thoughts, pet nutritionists have worked hard to deliver food for dogs with loose stools that are designed to help dogs with chronic loose stools out in any way they can. After carrying out product research, we’ve assembled what we regard as the best dog food for loose stools that will hopefully function as stool hardeners and taste delicious at the same time.

The Best Dog Food for Loose Stool


Purina’s formula is geared towards dogs who have a difficult time regarding digestion and sensitive skin. The prebiotic fiber in particular is optimal for digestion, as it keeps the digestive tract active and stools healthier. Featuring lamb as the principal ingredient, Purina wouldn’t dream of including by-products and instead focus on maintaining an optimal protein to fat ratio.

Purina’s decision to include mineral zinc in their kibble helps a dog’s immune system fight any bacteria and viruses present by promoting the production of antibodies that fight intestinal pathogens. Combined with omega-6 and omega-3 fatty acids that support joint health, your dog will start to feel like themselves again in no time.

Following a diet with limited ingredients is highly beneficial for all canines’ health, yet for dogs who often produce loose stools, following this type of diet is imperative.

Instinct take the limited ingredient philosophy seriously by only including one protein and one vegetable in their kibbles – in this particular formula, they’ve chosen salmon and peas to create a robust blend of delectable flavors. The salmon is certainly not by-product standard and instead is a wonderful, high-quality food source.

Yet the principal technique that allows Instinct to stand out from the crowd is all down to coating their kibble in freeze dried raw. This method reaps two principal benefits: firstly, the kibble retains its unrefined, pure flavor. Secondly and most importantly, this method augments the nutritional benefits by ensuring the levels of antioxidants and natural omegas are maintained rather than lost through baking processes. By advocating for concentrated forms of protein, Instinct are leading the way in natural dog food. We’ve got our eyes peeled for what they’ll do next.

What Causes Loose Stool in Dogs

There are numerous factors that can be blamed for your dog producing loose stools. We’ve discussed three of the most common determinants below:

Scavenging: Dogs are scavengers and, to our disgust, love nothing more than when their sniffing leads them straight to a tasty morsel on the side of the road. Enjoying this form of ‘street food’ may result in your dog suffering from a very upset stomach hours later.

Stress and Emotional Turmoil: Dog owners have come to associate barking and pacing as their pet experiencing stress, yet digestive issues aren’t thus far a widely acknowledged symptom. If a dog has been left alone for long periods of time in your home, has recently lost a close family member or moved house, the assumption that their unsettled digestive tract may be due to stress is even more likely. This is important to remember when your dog is incontinent – they should not be scolded, but nurtured as this occurrence may be a symptom of anxiety.

A sign of a more serious underlying health condition: If your canine hasn’t had a proper bowel movement in several days, this is their body’s way of communicating that something isn’t quite right. Several of the more serious underlying health conditions you may be dealing with are liver and kidney disease or pancreatitis. Therefore, it’s important to get your dog to a vet as soon as possible.

What to Look For in a Dog Food For Loose Stools

Plenty of probiotics: An abundance of probiotics in dog food is necessary if a brand wants their kibble to be acknowledged as food for dogs with loose stools. The definition of probiotics as “living microorganisms, which when administered in adequate amounts confer health benefits on the host” by the World Health Organisation proves exactly why they should be included in all dog food. A dog’s gut microbiome – defined as the unique collection of hundreds of different types of single-celled microorganisms in its digestive tract – is balanced out by this ‘good’ probiotic bacteria, thereby improving a dog’s digestion. As probiotic microbes don’t tend to hang around in a dog’s digestive tract, the switch from a traditional formula to one which is adapt at dealing with digestive issues is recommended.

No grains containing gluten: Dogs are perfectly capable of digesting some grains due to their production of pancreatic amylase – a digestive enzyme that allows the body to break down carbs. However, dogs should not be fed grains high in gluten such as corn and wheats. If fed gluten, dogs who are sensitive to gluten and those who suffer from a gluten intolerance experience their immune system attacking their gastro intestinal tract, thereby damaging the intestinal lining.

Benefits Of Food for Dogs with Soft Stools

Nutrient ratios are taken incredibly seriously: Unlike budget pet food that sells itself by proclaiming how delicious your dogs will find it, food for dogs with soft stools actually have an objective to achieve. Therefore, this sub-set of dog food is made by innovative, high-caliber brands who focus on attaining the optimal ratios of protein, carbohydrates, and fiber required for your dog to thrive.

A limited ingredient diet: As your pet will be exposed to less ingredients with. limited ingredient diet, the risk that one of them will disturb their gastrointestinal tract is reduced. Besides, the ingredients that are included must contain a large amount of nutrients to achieve the same heath benefits that containing a number of ingredients would do.

Best Dog Food for Diarrhea FAQ:

Q: How can I safely adjust my dog’s diet?

A: One of the primary reasons that dogs have diarrhea is due to switching too rapidly from one kibble to another. To our horror, many owners simply switch from kibble to kibble without a second thought, causing their dogs significant gastronomical upset.

To safely adjust your dog’s diet, a gradual incorporation of new kibble for old kibble is necessary. The ratios should resemble the following:

  • Days 1-2: 75% old kibble and 25% new kibble
  • Days 3-4: 50/50 split between old and new kibble
  • Days 5-6: 25% new kibble and 75% old kibble
  • Day 7: 100% new kibble

Q: What are good homemade food recipes that can help improve dog’s loose stools?

A: Made with love, homemade recipes to make your dog’s poops more solid should be filled with fiber and natural goodness. This reliable recipe has been taken from site topdogtips and, although it certainly doesn’t look appetizing, will help get your poorly dog back on the right track.


  • 1 boneless, skinless chicken breast (large)
  • Two tbsp. live culture plain yogurt
  • 1/2 cup canned pumpkin
  • 1/2 cup white rice (uncooked)

To start, take your half a cup of uncooked rice and cook it in accordance with the instructions on the box. If you’re a natural procrastinator, boil the chicken alongside the rice. Once you’ve thoroughly checked that the chicken is cooked through, cut it up into small chunks: your dog will struggle to digest large pieces of chicken, especially when their digestive system is already struggling.

When the chicken has been broken up into bits, mix it together with the rice, pumpkin, and plain yogurt and voila – you’re done! Now all that’s left is to wait on the bowl to cool down so your poorly dog can enjoy their treat without hurting their tongue too.

*Warning: Do not feed your dog this meal on top of their normal calorie intake. Instead, substitute 30% of this recipe for their regular kibble*
