Bacterial imbalance

It is very common for dogs to have bacteria in their small intestines. But the overgrowth of bacteria can be a big problem. Because their overactiveness affects the function of the organs, and as a result, loose stools can happen. Also, when it becomes more serious, your dog’s weight can be lost.

On the other hand, bacterial imbalance causes dehydration in dogs, which is one of the biggest risk factors for small dog breeds. Therefore, the bacterial imbalance couldn’t be as easy as you think.

Since this is more frequent, you need to pay more attention to the bacterial imbalance.

The actual reason for food allergies in dogs is unknown. Surprisingly, 70% of food allergies correspond with the most commonly fed foods. Besides, there is a high chance of catching food allergies in dogs between the ages of 1 and 3 years old.

According to the researchers, dairy products, beef, wheat, lamb, and chicken are common foods that cause allergens in dogs, and also, fish, boiled eggs, and rice are known as safe foods for dogs.


Having ulcers in the digestive tract is another cause of sensitive stomachs in dogs. Most of the time, ulcers happen because of accidental poisoning. It can be plant intoxication, chemical poisoning, or rodenticide toxicity.

Most of the time, this happens unknowingly. Giving low-quality commercial foods for a long time can lead to chemical poisoning. If you are giving commercial foods to your dog, then get a recommendation from your veterinarian.

Rather than making sensitive stomachs for dogs, ulcers can be very critical. It can develop into a tumor stage like gastrinoma (tumor in the pancreas or duodenum) and adenocarcinoma (tumor in epithelial tissue).


Tumors in the stomach are very rare among dogs. But when it happens, it can be very critical and have a low chance of surviving.

When your dog has a tumor in the stomach, it will become more sensitive than usual. Unfortunately. In the very beginning, stomach tumors show very few symptoms, that many dog owners ignore.

Adenocarcinoma (tumor in epithelial tissue) is the most common cancer in dogs. This usually happens in the lower third of the stomach. When it shows more progress, it often spreads into the nearby liver and lump nodes. When it becomes more severe, the whole digestive tract becomes more dysfunctional.

Other Parasites

Other parasites are all over your typical environment. Among them, “worms” play a significant role in making a dog’s sensitive stomach. In addition, ticks, fleas, and mosquito bites are more frequent.

Eating infected feces is another reason for sensitive stomachs in dogs.

Don’t underestimate parasites because they can be life-threatening if left untreated.


  • Living with new family members

  • changing the dog’s daily activities,
  • new pets, and

Diet changes

Another major reason for sensitive stomachs in dogs is diet changes. Increasing protein content in large quantities at once is not a good thing. If you want to increase the protein amount, you must do it step by step.

How to soothe sensitive stomachs in dogs?

Provide a simple diet with limited high-quality ingredients, such as chicken and rice. Be sure to keep the pet’s environment clean. Don’t forget to clean the food and water bowl regularly. Besides, it is essential to improve gut health by providing supportive supplements.

What are the supplements that relieve sensitive stomachs in dogs?


Probiotics help the digestive tract run smoothly. In the same way, probiotics improve healthy bacteria in the stomach and absorb nutrients like vitamins and minerals. Then make those nutrients available to the body. Unfortunately, there are not enough probiotics in commercial dog foods. So adding plenty of probiotics to your dog’s diet is necessary. If not, food will move slowly and digestive functions may be disrupted. This will lead to constipation.

In addition, probiotics

  • It helps to maintain a healthy biome.
  • promote overall gut health.
  • Produce key vitamins
  • Produce enzymes
  • Keep the balance of gut PH

Since there are many types of probiotics, such as lactic acid probiotics, yeast probiotics, and spore-forming probiotics, before buying them, please take advice from your vet.

The amount to be given is determined by the probiotic type and according to the dog breeds. Dogs with long intestines and eating high starchy foods on a regular diet can have probiotics without any problem. But dogs with small intestines couldn’t handle the overgrowth of bacteria. This can lead to another big problem.

Therefore when you give probiotics follow your veterinary advice and get rid of your buddy’s sensitive stomach problems.
