2. Rachael Ray Nutrish Limited Ingredient – Budget Buy

Rachael Ray Nutrish Limited Ingredient Lamb Meal & Brown Rice has only six ingredients, and they’re all vital for your pup’s nutrition. The recipe omits anything your pup doesn’t need, as it contains no fillers, artificial preservatives, flavors, or colors.

Lamb meal is the first ingredient, which is an excellent protein source for smooth digestion, and it’s followed by brown rice. This food is a terrific choice if your pup has a chicken allergy. It does include chicken fat, but that should not interfere with the allergy, and chicken fat provides omega fatty acids.

This dog food contains all the vitamins and minerals your dog needs on a daily basis, and it also includes taurine for eye, brain, heart, and digestive health.

The kibble size may be a bit large for smaller breeds, and some dogs do not tolerate the new formula that well. However, it’s the more affordable option on our list, making it a great budget dog food for firm stools.

3. Hill’s Prescription Diet Gastrointestinal Biome Dog Food

Hill’s Prescription Diet Gastrointestinal Biome Dog Food is a prescription diet formulated by nutritionists and veterinarians to promote a healthy gut.

Chicken is the first ingredient, and it has a good fiber content of 17%. With your dog’s digestive system at the forefront of developing this recipe, your dog should have firmer stools in no time while on this food. The added oats and pecan shells provide excellent fiber sources, and Hill’s has been at this for over 70 years, proving they’ve done their homework when it comes to pet nutrition.

A drawback is this food is available through prescription only, and it’s expensive and may not work for everyone’s budget.

Buyer’s Guide: Selecting the Best Dog Foods for Firm Stools

Now that we’ve reviewed our top eight picks of the best dog food for firm stools, let us now answer a few questions that you may still have about these types of dog food. Sometimes, it takes trial and error to find a dog food that works well for your pooch, and other times, you may need to consult with your veterinarian to determine the cause of your dog’s diarrhea. Nonetheless, let’s address some common questions and concerns.

What Causes Loose, Watery Stools in Dogs?

Loose, watery stool can arise when your dog eats something that simply doesn’t agree with its digestive tract. Loose stool can happen when fecal matter moves too quickly through the digestive tract and loses water and nutrients along the way.

Like humans, sometimes dogs may have irritable bowel syndrome (IBS) or have been exposed to salmonella. Other reasons for loose and watery stools could be coming from parasites, such as roundworms, hookworms, whipworms, and even giardia. More serious conditions could also cause loose stools, such as intestinal cancer or kidney and liver disease.

If diarrhea persists for more than 24 hours, contact your veterinarian to get a proper diagnosis.

What Can I Give My Dog for Watery Diarrhea?

Sometimes, dogs simply get into something that causes diarrhea, like eating spoiled food from the trash or finding a tasty-looking bug in the backyard. Luckily, there are home remedies you can try to help your pooch feel better. Canned pumpkin can do wonders for your dog’s diarrhea. Pumpkin is rich in fiber, and the soluble fiber in pumpkin will help bulk up the stool. You can also feed a bland diet of boiled chicken with white rice, but be sure to skip any seasonings. Feed this until the diarrhea subsides. Remember that if diarrhea continues for more than 24 hours, a trip to the vet is warranted to ensure nothing serious is going on.

What Ingredients Should I Look for to Make My Dog’s Stool Firm?

Any dog food you feed should contain high-quality ingredients with real meat as the first ingredient for dense protein and healthy veggies that provide a sufficient amount of fiber. Some recipes include pumpkin, which we know is an excellent fiber source. Prebiotics and probiotics are also excellent to incorporate into your dog’s diet, as they help with overall digestion and keep healthy bacteria in the gut.

Dry dog food is better than wet food for firmer stools because canned food has more water and a much higher moisture content, and your dog will not require too much water in their food when you’re trying to bulk up the stool.

How Hard Should My Dog’s Stool Be?

You should be able to pick the stool up easily with a poop bag. It should not be squishy or, of course, runny. It should look like logs and be firm. The stool should not be dry and hard, either.

Constipation can come from too much protein, and if you’re unsure how much protein your dog requires, your vet can assist you in feeding the correct amount for healthy and firm stools, as the amount is typically determined by your dog’s body weight.

Final Thoughts

For the best overall dog food for firm stools, Ollie provides human-grade ingredients that are fresh and healthy without any fillers for the best overall dog food. Rachael Ray Nutrish Limited Ingredient uses only six, top-quality ingredients, making it a great budget option.

We hope our reviews help you in selecting the right dog food for healthy, firmer stools for your pooch.
