​Reasons ​Dogs Suffer From Stomach Sensitivity

Every dog is individual and what triggers stomach sensitivity in one, may not in another.

There are many causes of stomach sensitivity and upset among dogs ranging from food allergies, digestion and absorption issues, and diseases, etc.

Establishing the underlying cause of your canine’s stomach sensitivity can be quite difficult; it might take a trial and error process.

Let’s have a look at some of the common causes of stomach sensitivity:

1. Allergic To Particular Food Components

Some dogs can be allergic to dairy products such as milk or cheese, leading to poor digestion and/or absorption.

The end result is stomach upsets, diarrhea, and excretion of these dairy products as a whole in faces.

Also, your dog could be allergic to certain types of fruits or fruit-related products.

Such dogs are likely to suffer from diarrhea and stomach upsets due to poor digestion and/or absorption of the particular type of fruit.

2. Food Intolerance

This is the most common cause of stomach sensitivity in some dogs, and commonly occurs due to poor digestion and/or absorption of certain food products – mainly protein sources as well as fat.

The insensitivity arises due to the nutrient composition of the diet that makes it difficult to digest, especially the proteins.

Some of the most common dog food that could trigger stomach upset include:

  • Fish
  • Beef 
  • Eggs 
  • Soya 
  • Lamb 
  • Wheat

Determining the underlying nutrient component that triggers stomach upsets in your furry friend is vital in finding a lasting solution to their stomach sensitivity.

Also, look out for easily digestible protein sources such as chicken.  

3. Changes In Immune System Function

Intestinal infections can interfere with good bacteria that produce enzymes that aid food digestion.

This can lead to minimum production of digestion-friendly substances thus affecting the normal food digestion and absorption.

The end result is likely to be stomach upsets and diarrhea.

4. Poor Digestion Of Dog Treats

Certain dog food treats may contain ingredients that are not easily digestible.

If you have fed your dog more treats than their digestive system can handle, this can cause poor digestion and absorption of the treat, leading to stomach upsets and diarrhea.

Sometimes it can just be the type of treat you have fed them, and depends on its ingredients.

Other causes include:

  • Giving your pooch human food.
  • Household habits. For instance, taking leftover food.
  • Diseases such as cancer.

Symptoms Of A Sensitive Stomach 

Most dogs with sensitive stomachs exhibit particular symptoms, however note that some dogs will display more of these symptoms than others.

While the most common symptom is stomach upset, other symptoms include:

  • Diarrhea / loose, watery stool.
  • Vomiting.
  • Flatulence.
  • Weight loss.
  • Loss of appetite.
  • Abdominal pain / Discomfort.
  • Skin rashes.

Note that some of these symptoms could manifest a bigger underlying health concern, so it is advisable to visit your veterinarian for a full physical examination and treatment.

Ingredients of Dog Food that can Trigger Stomach Sensitivity

1. Dairy Products

Dog food that contains dairy products tends to cause stomach sensitivity, most especially due to the presence of lactase – an enzyme that aids the complete digestion of whole milk.

The lactose intolerance is especially common in elderly dogs.

2. Gluten

Gluten is commonly found in cereals such as wheat, corn, and soy.

Digestion and/or absorption of gluten can prove difficult in some dogs leading to intolerance.

3. Fruits And Fruit-Related Products

Fruits are broken down into fructose molecules during digestion.

Due to the absence of some carrier molecules in the dog’s intestines, the absorption of fructose can become quite difficult.

Consequently, leaving high amounts of fructose in the small intestines that often cause diarrhea and stomach upsets.

Characteristics of Good Dog Food for Sensitive Stomachs

1. A Limited Number Of Ingredients

While your furry friend needs a well–balanced diet for optimal growth, having too many ingredients may be detrimental to the digestive system leading to stomach upsets and diarrhea.

Therefore, choose for her high quality dog food that contains limited ingredients preferably hypoallergenic dog food.

Remember, the more the ingredients the higher the chances that one of the ingredients might affect their sensitive stomach.

2. Grain-Free / Easily Digestible Grains

Since glutens found in some cereals like wheat, corn, and soya may cause stomach upsets in some dogs, having a grain-free diet would be ideal.

Some reports have linked grain-free dog foods to the development of Dilated Cardiomyopathy (DCM), however the evidence is currently inconclusive.

Therefore, instead of choosing a grain-free diet for your canine, you may opt for easily digestible grains for your dog’s food.

3. Food With Ingredients That Aid Digestion

Choose a dog food that contains substances such as probiotics that enhance the digestion and absorption process.

In particular, the lactobacillus species is a good bacteria that enhance the production of the lactase enzyme to aid in the digestion of lactose.

Therefore, probiotics substances reduce the incidence of stomach upsets.

Also, high-fiber ingredients in the dog’s food aid digestion, absorption, and bowel movement.

3. Lowest Protein Diet

Generally, proteins not only take longer to digest and absorb into the body but it also takes great work.

With limited protein intake, the digestive system will be able to work more efficiently reducing the incidence of stomach upsets and diarrhea.

Hence, look-out for a dog food comprising of limited protein content

4. Easily Digestible Food

Dog food containing easily digestible components, that is, both carbohydrates and proteins reduces the chances of your canine suffering from stomach upsets. 

Some of the dog food ingredients that are easily digestible by dogs include brown rice, potatoes, chicken, and lamb.

5. Bland Composition

Unlike the average dog food formula that might comprise of proteins, fruits, and vegetables, the best dog food for sensitive stomach should contain fewer ingredients.

Preferably one or two easily digestible protein and rice is an ideal composition to minimize stomach upsets.
