What To Look For In The Best Dog Food For Loose Stool

Your dog’s health depends largely on the diet you give her. After all, many health disorders in canines are direct results of a poor diet.

While there are thousands of dog food options out there, many commercial dog foods are sadly made of inferior quality ingredients and artificial enhancers. 

This is why it’s vital for dog owners to check carefully the label of the dog food products and be guided on what to look for in the best dog foods.

High Quality and Natural Ingredients

Whether your pup has health issues or not, always go for the best dog food that you can afford. And the best dog foods are always made with high-quality and natural ingredients.

The best ingredients for dog foods are made with real animal meat and wholesome foods. Check the ingredients deck for the first five ingredients. 

The first two components on the list must be high-quality animal protein sources from a named animal. Don’t settle for an unnamed animal source, e.g. animal derivatives, meat meals, meat by-products.

Even the plant-based ingredients must be from fine quality whole food and not cheap grains. Additional digestive enzymes may be supplied by fruits and veggies to aid in a dog's sensitive stomach.

Also, some dogs have food allergies to certain common food ingredients like dairy, eggs, beef, chicken, and some grains. This is why it’s very important to review the ingredients in your dog food.

Remember, poor quality dog food may save you some money but you could be spending more on medication and visits to the animal clinics.

High in Fiber

For a dog’s loose stool, it helps to have more fiber in the diet. The fibers help in densifying the poop by absorbing the fluids.

The fibers in dog foods are supplied by plant-based ingredients like beans, peas, legumes, nuts, broccoli, potatoes, apples, pumpkin, and grains. Fibers are beneficial to the digestive system too. Choose a dog food with a fiber content of at least 5%.

High in Protein, Low in Fat

Choose a dog food that offers more proteins and less fat. The extra proteins can aid in solidifying the poop, while too much fat can only aggravate diarrhea. So if your pup has diarrhea, look for a low-fat diet. For dry food, the crude fat should not be over 20%.

Probiotics and Prebiotics

For healthy digestion in dogs, dog foods with probiotics are preferred. Probiotics such as Lactobacillus Acidophilus and Lactobacillus Casei are good bacteria that support the digestive tract and protect it from bad bacteria. Probiotics also aid in the absorption of nutrients, enhance detoxification in the body, and boost the immune system.

Prebiotic fiber refers to non-digestible fibers derived from whole foods that augment the growth of probiotics in the colon.

Complete and Balanced Nutrition

Your dogs not only need clean and natural ingredients in their food to achieve optimal health. They also need complete and balanced nutrition in their meals.

Apart from the essential amino acids, canines will also need a number of vitamins and minerals to boost their overall health.

Most of the best dog foods are fortified with these essential nutrients, plus sufficient antioxidants and omega fatty acids to strengthen the immune system, heart, and brain health, and attain a healthy skin and coat.

No Food Allergens

It’s very possible that the root cause of your dog’s loose stool is a food allergen in dog food that triggers a digestive disturbance resulting in unhealthy poop.

Studies identified the following protein sources as common food allergens in dog food – beef, chicken, lamb, eggs, dairy, soy, and wheat gluten. 

Although not all dogs have food allergies and intolerances to certain proteins, it’s probably better to avoid these ingredients when your pup is having allergic reactions like diarrhea. Most specialized food formulas for sensitive skin and stomach avoid these ingredients.

Limited Ingredients

Additionally, if your furry friends have symptoms of food allergies and food sensitivities, it may be safer to go with a limited ingredient dog food, especially if you don’t exactly know which ingredients cause the reaction.

There are many limited ingredients diet dog foods to choose from. Also, if you’re unsure of the food allergen, it may be best to get a limited ingredient diet grain-free formula as some grains are known to induce allergic reactions in dogs too. 

A good-quality and limited ingredient diet grain-free dog food could be the best food, at least until the symptoms are gone.

Free of Artificial Flavors, Colors, and Preservatives

Avoid getting dog foods that contain artificial colors, flavors, preservatives, or any other non-natural ingredient. Natural ingredients compose the best dog foods.

Many pet food manufacturers settle for artificial ingredients to keep costs down and prices low. But unhealthy ingredients also turn into excessive medical bills for dog owners in the long run. The best food only contains natural components.

Manufactured in Countries with High Safety and Quality Standards

For your peace of mind, choose dog foods that are created in countries with very strict safety and health standards in foods.

Countries like the United States, Canada, Australia, New Zealand, and some European nations have very high standards in pet food production, which protect your pets from common health hazards obtained from commercial pet diets.

About Diarrhea And Loose Stools in Dogs

What Causes Diarrhea and Loose Stools in Dogs?

There are several possible causes for loose stools and diarrhea in dogs. First of all, a soft stool doesn’t necessarily mean diarrhea. Loose stools from diarrhea are more watery or very soft. Some loose stools are just not firm enough to be considered a healthy poop. 

Diarrhea is usually caused by the consumption of toxic and unhealthy food like rancid food, while soft stools are normally the product of a poor-quality diet, insufficient fiber, too much fat, or food sensitivities and intolerances.

Healthy dog stool looks firm but not dry. A dry stool typically means constipation, which is also an unhealthy situation for your dog. 

According to the American Kennel Club (AKC), there are 12 common causes for a dog’s loose stools, namely:

Change in diet

It normally takes a few days for a dog’s gut system to adapt to new proteins, for instance, if you shift from chicken to lamb, or beef to fish. The best way to transition to the new food is to gradually change the proportion of old food and new food in about a week’s time. A sudden shift to unfamiliar food could result in loose stools.

Food intolerances

Some dogs are food intolerant to some foods, which can cause unhealthy poop. The most common food intolerance is lactose intolerance caused by milk, yogurt, and other dairy products.

Food Allergies

An allergic reaction to food could trigger diarrhea or at least provoke the dog’s GI tract, which could result in loose stools.

Parasites

Some parasites like roundworms and hookworms are known to potentially cause soft stool in canines with a poor immune system.

Dietary Indiscretion

Dogs, especially outdoor dogs, are prone to digesting unhealthy foods like spoiled or rancid food, or inedible objects, dead animals, and garbage. If you have a rescue dog, he may be used to eating food from any surface. These unsanitary items can upset the stomach.  

Poisonous substances or plants

Toxic substances are rejected by the digestive system resulting in diarrhea or loose stool.

Viral Infections

Some viruses like parvovirus, distemper, and coronavirus are among the common viruses that can cause diarrhea and loose stools in dogs.

Bacterial infections

Various bacteria such as Salmonella and E. Coli are also known to trigger diarrhea and loose stool in dogs.

Illnesses

An illness or disorder in canines such as kidney and liver disease, colitis, and cancer can disrupt the digestive system and cause loose stool and diarrhea.

Antibiotics and other medications

Some medications like antibiotics also cause the digestive system to react adversely and cause loose stools.

Stress or Emotional Upset

When your dog is anxious or upset, the digestive system somehow reacts adversely as well, resulting in loose stools, or even diarrhea.

Overfeeding

Overfeeding could also trigger loose stools according to vets. This is typically indicated by the dog’s poop getting softer throughout the day from a firm first stool in the morning.

Is Dog Diarrhea Life-Threatening?

Diarrhea is not an uncommon health condition in dogs. Most cases are temporary and normally last for just a day. Observe your dogs.

If the symptoms persist after 48 hours, it could be a more serious condition or chronic diarrhea, in which case it’s best to see the animal doctor.

Other symptoms in more serious cases of diarrhea include:

• Fever
• Blood in the stool
• Blackish stool
• Vomiting
• Bloating
• Nausea
• Loss of appetite
• Drop in dog’s energy

Conclusion 

Loose stools happen once in a while in dogs. A number of possible causes are known to result in canine diarrhea and loose stools. 

One of the most common roots is a simple change in the dog’s diet, which upsets the digestive system and needs time to adjust to the new food.

Changing dog foods is pretty common, and sometimes necessary. What you can do to avoid loose stools is to slowly transition from the old to the new food, by changing the proportions each day for about a week.

Healthy food is necessary not just to prevent diarrhea or loose stools but also for a long, healthy, and happy life for your canine companions. Choose the best quality dog food that you can afford. 

The best quality diets are made of high-quality ingredients and clean animal proteins from a named animal. Balanced and complete nutrition is also ideal, with all the essential omega fatty acids, vitamins and minerals, and antioxidants vital to a dog’s health.

To firm up your dog’s loose stools, it helps to feed her dog food, preferably dry dog food, that’s high in protein and fiber, low in fat, and with probiotics and prebiotics. If your pup is food sensitive, check the ingredients list for the presence of food allergens.

Also, always provide your dogs with fresh water in a clean bowl daily along with the meals. Keep their surrounding areas clean and disinfected too. 

Consult the veterinarian if your dog’s poop remains soft beyond 48 hours.
