Chihuahua Digestive System Diseases

What does the digestive system do?

The digestive tract starts in the mouth where food is mixed with saliva which contains digestive enzymes. In the mouth, food is chewed into smaller bits which are swallowed. The esophagus pushes the food towards the stomach where it is mixed with acids that contain proteïn-processing enzymes. In the stomach food is processed into even smaller bits of food that pass to the duodenum. In here enzymes from the pancreas and gal from the liver come together to start a process that breaks the food down to fats, sugars and proteins. These fats, sugars and proteins are absorbed in the intestine which passes these important building blocks for the body into the blood stream. In a final step faeces is excreted through the rectum.


If your Chihuahua shows following symptoms it might have a problem with its digestive tract:Chihuahua Digestive System Diseases

  2. Loss in weight
  3.  Problems with swallowing
  4. Throwing up
  5. Swollen belly
  6. Flatulence
  7. Diarrhoea
  8. Constipation


In order to diagnose digestive tract problems you need to consult with your local vet. He has a number of tools which can help identify the problems your Chihuahua might be facing:

  1. A decreased level of enzymes in the saliva can indicate a problem with the intestines
  2. The vet can take a blood sample, the presence of certain bacterias and/or parasites might cause digestive tract problems
  3. The presence of blood, parasites and/or viruses in the stool can indicate a problem with the wall of the intestines
  4. In case the previous methods cannot determine the cause the vet might have to take an x-ray or an endoscopy of the affected area.


Depending on the underlying problems treatment for digestive tract problems can vary widely. In case of an infection the vet can prescribe antibiotics or anti-inflammatory drugs. In case the problem is located in the intestine, enzyme supplements can be prescribed in order to support digestion. Finally in case of parasites your Chi will have to take antiparasitic medication.
