Best Dog Food for Dogs With Diarrhea and Loose Stools and How to Feed Your Dog

Dog Food for Dogs With Diarrhea

Before You Switch Your Dog's Food

If you notice that your pet has diarrhea one time, you don't need to fret immediately.

Keep a close eye on his bathroom activity, and take him outside to do his business more frequently than normal.

If you notice the stool progressively getting more firm over the course of his next few bowel movements, you've got nothing to worry about.

However, if you notice a loose stool and then it gets progressively looser, it's time to get concerned.

If your pup just ate something that he shouldn't have, it will pass through his system in about 24 hours.

If there is something more serious going on, the bout of diarrhea will last longer, and you will need some upset stomach treatment.

Aside from switching to the best dog food for dogs with diarrhea, there are some other options that you can try first, including:

1. Fasting

Dog Food for Dogs With DiarrheaAnywhere between 12 and 24 hours, the dog should fast.

Feeding your dog during diarrhea is (a) pointless because diarrhea is the very act of pushing food out of the body overly fast.

Plus, (b) feeding the dog will further stress the stomach and aggravate the condition.

2. Hydration

Diarrhea causes a lot of dehydration for the body, so your doggy must drink water.

Sometimes, diarrhea can cause some apathy, so you’ll need to encourage the dog to drink.

Make sure it doesn’t drink too much either; however – put a little water in the water bowl regularly and refill when the dog has drunk it.

3. End the fasting with a specialized food

Once the fasting period is over, it’s important not to go back to the dog’s regular diet.

Either consult with a veterinarian on a specialized prescription diet or try some bland food yourself.

We will go over some commercial alternatives in detail below, but the idea is to feed your dog with gentle food on the stomach – nothing fatty, rich, and spicy or with red meat.

Serve either some skinless, non-flavored chicken with rice/pasta/potatoes or prescription food for healing stomachs – nothing else.

Especially avoid all dairy and eggs – dairy is bad for dogs in general, but while eggs are acceptable overall, avoid them on a sensitive stomach after and during diarrhea.

4. Ration the food

Along with the best dog food for dogs with diarrhea, smaller portions are much better for the stomach in general.

That’s especially important when he is healing.

You don’t need to feed your dog less than you normally do once the fasting over. However, it would be best if you fed him far less per portion.

For a rule of thumb, make the portions two or three times smaller and feed the dog two or three times more often. This will prevent diarrhea and stomach problems from reemerging.

5. Take your time transitioning back to a normal diet

Once the diarrhea is 100% passed, don’t go directly back to the dog’s regular food.

Transition him slowly so that the bowl has had enough time to heal and is not irritated by the frequent changes.

Dog Food for Dogs With DiarrheaGenerally speaking, keep the dog on the “healing diet” of bland food or prescription food for 2-3 days (or more, if the vet has said so).

Afterward, slowly take the next 2-3 days to transition from it to the dog’s regular food (or new food, if the vet has advised against what you’ve been feeding your dog so far).

During the transition, mix the food as follows:

  • Mix two-thirds of bland food with one-third of regular food on the first day.
  • Mix one-third of bland food with two-thirds of regular food on the second day.
  • Go to regular food on the third day.

6. Add supplements if necessary

The best dog food for dogs with diarrhea may not be the only change you need to make to his diet.

You may also need to add probiotics or whatever other medication or supplements your vet has suggested.

Just as with humans, probiotics are essential after diarrhea.

During diarrhea, the organism loses many of the bacteria that help with digestion, so probiotics should be administered to cultivate a new population of bacteria in your dog’s bowels.

Usually, 5 days of probiotics mixed into the dog’s food are enough but consult with your vet if the diarrhea was more extreme.

Keep in mind that the natural digestive bacteria in dogs is very different from that in humans.

Do NOT give your dog human probiotics!

Dog probiotics are available, usually without prescription, at your local pharmacy, veterinarian's office, or pet store.

Other than probiotics, don’t give your dog any medication that isn’t recommended by your veterinarian.

Don’t give your dog any human medication, although that should go without saying in general, not only after diarrhea.

How Can Dog Food Help With Chronic Diarrhea in Dogs?

Dog Food for Dogs With DiarrheaSo, why should you feed the best dog food for dogs with diarrhea? Can’t you give the dog some medications?

No, the quality of the food is essential for the well-being of the dog, both during, as well as after diarrhea.

Dogs may be omnivores, but that doesn’t mean that they can literally eat anything and get away with it.

If you don’t care for your puppy’s tummy when it has diarrhea, you risk making it worse and causing some serious, long-lasting damage to his bowels.

Plus, a lot of dogs have sensitive stomachs and loose stool in general. Such dogs need a specialized diet all the time, not just after extreme episodes.

Diarrhea and loose stool make the dog’s stomach highly susceptible to many bacteria, diseases, allergic reactions, and other health concerns.

The best dog food for dogs with diarrhea has many advantages, whether it is prescribed or homemade (given that it is well-made).

The benefits of the best dog food for dogs with diarrhea include:

  • It prevents additional/prolonged diarrhea. Diarrhea may go away within a day, most of the time, but improper food can prolong it quite a lot and even turn it into something much more unpleasant than what it already is.
  • It prevents inflammatory bowel diseases. After diarrhea or loose stool, your dog’s stomach is at much more risk of bowel diseases.
  • It prevents allergic reactions. A loose stomach is in danger of many possible allergic reactions that it hasn’t experienced before. A proper bland diet prevents that.
  • It offers proper nutrition for your dog. a loose stomach has a hard time absorbing the nutrients from the food, which is why you need a more specialized diet to make up for that.

What Ingredients to Avoid

As you sort through the various options for dry dog food for your pup’s sensitive stomach, there are some ingredients you want to do your best to avoid. 

Whenever possible, stay away from soy, gluten, corn, and wheat. You also want to avoid corn syrup, rendered fat, animal by-products, artificial colors, BHA/BHT, and propylene glycol.

What Ingredients to Look For

Just as important as knowing what ingredients to avoid is knowing which ones to look for and include. 

  • Ingredients that are highly digestible – You want to look for ingredients that your dog will find easier to digest. Good options include chicken, lamb, rice, and potatoes. You can also look for foods with high fiber content to help solidify your dog’s stools. Moderate fat content is also ideal, as too much can cause pancreatitis. The ideal would be about 5-20%. 
  • Probiotics – These helpful bacteria can improve digestion. Just keep in mind that formulas with probiotics will have expiration dates that are potentially shorter than with other foods, as the bacteria must still be viable.

Is Dry Food or Wet Food Better for Gut Health? 

As with the normal food you give your dog, there are pros and cons to both dry and wet food. 

Dry food tends to make storage easier, and it tends to be more affordable. You have to be extra careful with the ingredients, though, as dry foods frequently have gluten and grains and more carbs overall. 

Wet food tends to be tastier. The fact that it is softer can also make it easier on the stomach. However, you will need to refrigerate it and pay attention to the expiration date. It is also more expensive. 

Overall, the ingredient list is more important than whether you go with dry or wet food.

General Tips for Dogs with Sensitive Stomach

Before we go, a few things must be said about dogs with a sensitive stomach and how to feed a dog with stomach upset.

These few tips below will help you care for a dog with a sensitive stomach to avoid further complications.

As I mentioned earlier, finding the best dog food for dogs with diarrhea isn't the only worry you'll have. Keep these tips in mind as well:

Avoid giving your dog any human food and avoid threats from strangers in general. Make sure you know everything that’s going in your dog’s mouth.

Know all of your dog's allergies.

Always check your dog’s poop not just for diarrhea but also for blood and mucus.

Make sure your dog doesn’t eat too much fat and carbohydrates.

Limit all grains from your dog’s diet as well.

The foods to focus on are – brown rice, liver, beef, garlic, tuna, chicken, lamb, carrots, and broccoli – they will strengthen your dog’s stomach and intestinal linings.

Get a food bowl that slows your dog’s eating. Fast eating is a serious problem for proper digestion.

When buying commercial dog food, always go for the highest quality diet. Select certified dog food is worth it in the long run. It’s better to pay for food than for vet fees.

Change your dog’s diet regularly. Once every 2-4 months, you should change things up by adding and removing ingredients. Nothing too drastic; make sure that your doggie’s stomach sees enough variety.

Never change your dog’s diet too suddenly. Always change it just a little bit and in the span of a couple of days.

Avoid chocolate, raisins, ice cream, milk, or coffee at all costs. It’s important not just to give them to your dog but also to keep them out of its reach. Also, never give your dog any nuts like macadamia, walnuts, or peanuts.

Ensure he doesn’t have access to the garbage, as eating it can easily turn into a very unhealthy (and nasty) habit.

Avoid easy-splintered bones of poultry at all costs – they do far more harm than good.

The ideal intake of water for your dog is one ounce per pound of body weight per day.

Avoid raw eggs. If you are going to give eggs to your dog as a part of its homemade diet, always cook them beforehand – raw eggs bring the risk of salmonella not just for humans but for dogs as well.

Make sure to feed your dog with small but regular portions. He will generally eat everything you put in front of him, but smaller and more regular is better than bigger and less frequent when it comes to food.
