Why Do Dogs Have Loose Stools?

sick dog

Just about every dog will experience loose stool at some point, with causes ranging from food intolerance to illness. Some dogs may also suffer from more chronic bathroom woes.

The most common causes of loose stools in dogs include:

  • Illness: Bacterial infections or digestive disorders can trigger diarrhea or loose stools.
  • Stress: Anxious doggos often experience diarrhea when stressed, particularly those with separation anxiety or kenneled canines at boarding facilities.
  • Food intolerance: Unlike a food allergy that triggers an immune response, food intolerance can lead to noxious gas, diarrhea, and loose stools. 
  • Imbalanced intestinal flora: Gut bacteria exist in a delicate balance that can be thrown off due to illness or antibiotics, leading to digestive upset and stool issues. 
  • Insufficient fiber: A lack of fiber in your dog’s diet makes it difficult for solid stools to form in the digestive tract.
  • Too much fiber: While fiber is generally a good thing to incorporate into your dog’s diet, excessive amounts of fiber can lead to stomach upset and diarrhea. The extra fiber moves too quickly through the digestive system, not allowing the body to solidify poop.
  • Changing foods too fast: Switching your dog’s food should be done gradually to avoid stomach upset and issues with stool consistency.

Don’t try to self-treat diarrhea or loose stools at home, particularly in puppies and seniors that are extra sensitive to dehydration. A vet should see your dog to rule out underlying causes, especially if it’s a sudden, severe bout of diarrhea or chronic loose stools.

What Characteristics Do Dog Foods for Firm Stools Have?

dog food

The best dog food for firm stools isn’t one-size-fits-all, but the products share similarities, from the ingredients chosen to fiber content. Look for these when browsing potential foods if your vet’s given the OK to switch.

The best dog foods for firmer stools:

  • Feature a high (but not too high) fiber content: Again, fiber helps bulk up stools, but too much can lead to doggy diarrhea, bloating, and discomfort. 
  • Contain probiotics: A mix of probiotics can help restore balance to your dog’s gut flora, a biome easily disrupted by illness and some medications. Though more research is needed, multiple strains are thought by many to be more helpful than a single strain.
  • Have an ingredient list free of your dog’s food intolerance triggers: You don’t want to upset your sniffer’s stomach by feeding him food that doesn’t agree with his system. Always carefully examine the entire ingredient list, as some recipes use mixed proteins despite being labeled “lamb dog food” and the like.
  • Address any specific health problems your dog has: Many dog foods for sensitive stomachs are available today, along with other foods specifically designed to tackle canine health concerns, like hydrolyzed dog foods for mutts with multiple food allergies. 

It’s always a good idea to run a potential food by your vet first, as he or she knows your pup’s health and needs best. What works great for one pup may not suit another, especially if your pup has specific health concerns.

Great Solution for Temporarily Firming Stools: Pumpkin to the Rescue

pumpkin puree dog food topper

Your four-footer doesn’t always need an entire diet change for temporary belly woes. Sometimes, pumpkin is a quick fix that can firm up stools, so keeping a can in the pantry is a good idea with a canine in the house.

Pumpkin’s a solid source of fiber that can solidify your pup’s poops, plus it has critical vitamins and minerals that may be depleted if your dog’s dealing with diarrhea.

Just be sure you’re using plain canned pumpkin purees like Fruitables Digestive Supplement and not pumpkin pie filling, which is full of sugars, spices, and fats that can worsen your woof’s stomach issues. 

Remember: less is more with pumpkin. Too much pumpkin will introduce too much fiber, making your dog’s loose poops worse.

Most of the time, a teaspoon of puree will do the trick for a small or medium-sized mutt. At the very max, offer smaller pups two teaspoons. For large breed dogs, offer up to 4 teaspoons, but always start with two to three at first to see how your pooch’s system reacts.

Best Dog Food for Firm Stools: FAQ

pooping dog

Battling barkin’ bathroom issues isn’t easy, so you may still have some concerns surrounding stool-firming dog food. Let’s explore the most frequently asked questions about the topic.

What foods will firm up a dog’s stool?

Dog foods featuring plenty of fiber (without being too much) from vegetables and grains can firm loose stools. It’s also important to double-check the ingredient list for any potential allergens or triggers that can upset your pup’s stomach. Often, these are proteins like chicken or beef in doggos.

What is the best dog food for solid poop?

The best food for ensuring firmer, healthier poops is one with a balanced recipe of protein, carbohydrates, fiber, and vegetables, like Ollie Fresh Chicken with Carrots or Acana Wholesome Grains. Your pup’s food doesn’t need to break the bank, either. Diamond Naturals All Life Stages is a top-notch choice for healthier poops, too.

How do I stop my dog’s stool from being soft?

The best way to combat soft stools is to bring your dog to the vet for a thorough exam to determine what’s causing the issue, as it isn’t always easy to determine if illness, food intolerance, or something else is behind the problem. Treatment varies by the cause, with some doggos merely needing a temporary bland diet while others require medication or a complete food change.

If your pup needs more fiber in his diet, your vet may recommend offering occasional high-fiber dog treats or fibrous bonus ingredients to his bowl, like green beans or broccoli. Homemade pumpkin dog treats are another way to sneak more fiber into your dog’s diet in a tasty way. 

What food is good for dogs with soft stools?

The best food for a dog with soft stools will vary by what’s causing the bathroom issues, but usually, you’ll want to look for a digestion-friendly food with a focused ingredient list containing a single protein, grain, and a medley of fiber-containing veggies like pumpkin and sweet potatoes.

Check out JustFoodForDogs Balanced Remedy and Ollie Fresh Chicken with Carrots for a fresh option. See Sundays Food for Dogs and Blue True Solutions Blissful Belly if you’d prefer kibble.

Does pumpkin firm up dog poop?

Fiber-rich pumpkin can help solidify your dog’s poop but can also lead to diarrhea if you offer too much. Generally speaking, one to two teaspoons is best for a small to medium dog, while four teaspoons maximum is recommended for a large breed. 

As always, err on the side of caution and ask your vet before using pumpkin to alleviate bathroom woes. Sometimes, illness is to blame, and no amount of fibrous vegetables can provide relief.
