Changes in dog food can affect your dog’s poop. But the adjustment period is short-lived, and your dog’s poop becomes normal quickly.

My dog ate something on his walk; should I expect to see loose stools?

Dogs are natural scavengers and love to explore everything! Sometimes they will eat something inappropriate out on their daily walk. Depending on your dog’s gut activity, you might see signs soon after they’ve eaten it. If you notice runny stools, then seek veterinary attention. Make sure there is fresh, clean water available to help them stay hydrated.

Choose bland, easily digestible foods such as brown rice, yogurt, and oatmeal. You can also choose high protein foods such as chicken or eggs for easy digestion. Stick to this diet until your dog’s symptoms improve and his stool firms up.

Orange dog poop can indicate a biliary or liver issue, and you should discuss it with your vet.

Red streaks in your dog’s poop indicate blood presence. If you see blood in dog stool, we recommend checking your dog’s anus for cuts and investigate where the blood originates.

Why is my dog’s poop grey and greasy?

The 10 Best Dog Foods for Firm Stools

Hill’s Prescription Diet Gastrointestinal Food – Best Overall

Hill's Prescription Diet Gastrointestinal Biome

Hill’s prescription diet was formulated by a team of canine nutritionists and veterinarians to tackle the issue of gastrointestinal problems. It uses their exclusive ActivBiome technology, which is designed to work the bacteria in Fido’s gut.

By doing so, it breaks everything that he eats down as naturally as possible, and it passes through his digestive system with ease. It releases postbiotics, which supports his gastrointestinal tract (GI) to break down the food he consumes.

It will encourage healthy and firm stools, reduce the risk of unhealthy stools in the future, and improve his digestive system overall.

Real chicken is still the first ingredient, and it provides an overall well-balanced diet for his nutritional needs. The fiber content in this product is 9%, and ingredients such as ground pecan shells, oats, and dried beet pulp aid in the stool firming process.

This is a prescription formula, meaning that you have to have an authorized prescription from your vet to buy this product. But for those with a super-sensitive system, it is the best product available.

  • Only available on prescription
  • Gentle on GI tract
  • Releases postbiotics
  • Prescribed by vets
  • High fiber content

Rachael Ray Nutrish Just 6 Natural Food – Best Value

Rachael Ray Nutrish Just 6

This is our best value option because it is the best dog food for firm stools for the money. The size of the bag is considerably large, considering how much it costs, which is great for those owners who are on a tighter budget.

It is a limited ingredient diet with just six ingredients for simple digestion. It has everything that Fido needs to firm his stools and nothing that he doesn’t need. Lamb meal is the primary protein source, and it is the first ingredient, too, which is essential for his general nutritional needs. Lamb is known to be gentle on his gut.

It is a good option for those dogs who are allergic to chicken, which is the most common ingredient used in dog foods. The only reason this kibble didn’t make it into the number one spot is that it has a lower fiber content (4%), which for many, is not enough to firm stools.

Thankfully, there are some dogs out there who need a lower fiber content for firmer stools. So, this makes it an excellent option for them, or those dogs who need an average level.

Buyer’s Guide: Selecting Best Dog Foods to Harden Stool

Here is the section where we are going to walk you through a variety of things you need to learn or think about when it comes to your dog’s stools.

To understand how to rectify the runny stool situation, you need to understand what could be causing the problem in the first place.

It’s important to remember that not every dog is the same. So, if your vet hasn’t told you exactly how to tackle the problem, you might need to try a few options before you find the one that works for Fido.

When Should You Worry About Dog Diarrhea?

If he has diarrhea and it has gone on for longer than 48 hours, it’s time to take him to the vet. This is a strong sign that it is more than just a tummy bug or something that he has eaten.

Diarrhea can be a sign of intestinal worms, inflammatory bowel disease, colonic ulcers, polyps, or cancer, to name just a few. The sooner you get it looked at, the sooner you can get him on the road to recovery.

If your dog is experiencing any of the following symptoms in addition to runny stools, it is vital to get him to a vet straight away:

  • Fever
  • Bloating
  • Vomiting
  • Lethargy
  • Mucus or blood in the stool

You might get to the vet, and they’ll tell you it is because the current food that you are feeding him isn’t working well. And here, it is essential to switch him to a kibble that will rectify the problem, such as the ones above.

What Causes Soft Dog Stools?

  • Diarrhea is the result of little no water or nutrient absorption and fecal matter passing through his intestines too quickly. There are a variety of reasons why your dog’s stools arent as firm as they should be. And most of the time it is nothing to worry about.
  • Maybe he has eaten something that didn’t agree with him, or perhaps he picked up something he shouldn’t have on your recent walkies, such as bird poop or a spicy chip. It could be because he has an allergy to his food, or he is merely experiencing a little bit of stress.
  • Sometimes, however, it is a sign that something else is at play. It could be a symptom of a more severe problem that you need to get checked out.

What Ingredients To Look Out For To Harden His Stool

Nutrition is a great way to firm up his stools if it doesn’t require veterinary intervention. But, the issue here is that not all dogs are the same, and they need different things to firm up their stools.

How Firm Should Dog’s Poop Be?

  • A firm stool is one that you can pick up in a poop bag, and it does not squish in your hands as you scoop it up. If it resembles soft ice cream that is considered to be a soft stool. If it is like soup, well, we’ll say no more.
  • If it just happens once or twice, the likelihood is is that it is as a result of eating something he shouldn’t have done. If it happened regularly, it might be because he is allergic to something you are feeding him. Or he isn’t getting enough of something, such as fiber or nutrients. Or perhaps too much of something, such as fiber (yes, confusing!) or protein.
  • This is when you should switch his food to a gentler diet…

Natural Ingredients To Harden Dog Stool

  • Dogs with regular soft stools usually have sensitive systems that need higher quality foods. Higher quality foods usually list natural ingredients. Natural ingredients are definitely better for a dog’s digestive system, as this is the way that nature intended him to eat.
  • The exception is kibbles made by leading brands, such as Hills Science Diet, where scientists and veterinarians believe certain man-made ingredients are necessary. But they never use ingredients that are known to irritate digestive systems. Budget store kibbles, on the other hand, do.
  • Artificial preservatives, colors, or additives are known to agitate sensitive dogs, so steer clear of these ingredients. If you see ingredients such as butylated hydroxyanisole or ‘Blue 2’ or ‘Red 40’, put it back down on the shelf and move onto the next.

Dog Protein

  • Some dogs are allergic to specific proteins. And you can be sure that if Fido is allergic to chicken and you give it to him, his runny stools are the least of your worries. Lamb is often used in limited ingredient diets because they are gentler to digest. So if you suspect protein is the culprit, try him on a lamb based kibble.
  • Sometimes, dogs can struggle to digest kibbles that are too high in protein, and as such, you should look for a kibble that provides less. Again, this is all about working out what works for Fido.

Dog Prebiotics and Probiotics

  • Prebiotic fibers are essential for firm stools, because they essentially add bulk to the poop, making it less runny. Prebiotic fibers are wholesome veggies, fruit, and grains, such as bananas, chickpeas, chicory root, and oatmeal. So when you are checking out the ingredient label, if you spot any of these, it’s going to help toughen his poop.
  • To keep it simple, probiotics are the friendly bacteria that eats the prebiotic fiber. Ingredients to look out for are lactobacillus acidophilus and bifidobacterium animalis fermentation product, to name just a few. Many high-quality formulas will fortify their kibbles with these ingredients, which provide live yogurt cultures with every bite.
  • Fiber is a tricky one because too much and too little can wreak havoc with doggy digestive systems. And there is no way for you to calculate how much he needs.
  • 2% to 5% is the average fiber content in most kibbles, and a high fiber diet is anything between 6% and 12%. Most dogs with runny stools need a higher fiber diet, but if you have any questions, be sure to speak to your vet, who will be able to offer you tailored advice.

Yucca Schidigera Extract

With runny stools usually comes stinky gas, and if Fido’s poop or gas is smelling funky, this could ease the burden on your nostrils. Yucca schidigera is a herbal plant that is used in pet foods to reduce the smell of your dog’s poop. It can reduce the odor by up to 26%. Higher quality kibbles will list this ingredient, cheaper ones will not.

How Do You Know That It Is Working For Him?

  • Well, the proof is in the pudding, and when we say pudding, we mean poop. Once you feed him the new foods, follow him around when you notice he has the fidgets or watch him poop if you are out on walkies. This might sound odd, but you need to match the poop to the pooch.
  • If his poop is still just as runny over the next 48 hours, there is a good chance that his new food is not working. If it has firmed up slightly, there is a chance that it is. Keep an eye on his poop, and over 48 hours, or so it should start to firm up considerably.
  • Ultimately, all dogs are different, and he might need to kiss a few frogs before he finds his prince, as it were. The most important rule here is to listen to his needs, and follow what his body (and poop!) are telling you.

Final Thoughts

Hopefully, you now understand why your dog’s stools are runny, and what you can do to make them firmer. By feeding your pooch a better quality kibble that focuses on his digestive health, you are providing him better health and overall happiness.

You need to work out what works for him, and you’ll certainly know about it when it isn’t working for him. But when you find that perfect recipe, it will definitely be worth the trials and tribulations.

By sticking to our recommendations above, not only will you save yourself a lot of time searching through hundreds of different products, but you can be sure one of them will work for Fido. Thanks to the reviews, it’s simple to choose one that suits you, and Fido, best.
