Gastrointestinal diseases (usually associated with signs such as vomiting and/or diarrhoea) are some of the most common reasons dogs are taken to veterinary clinics. Some mild problems may resolve once the digestive system is given a chance to rest. Other more complex or serious conditions may require investigation and further treatment.

With gastrointestinal problems, diet plays a crucial role in helping the condition resolve, and when diet is combined with other treatments most dogs will be able to make a complete recovery.

The gastrointestinal tract is primarily designed to digest food and absorb nutrients. Food, after chewing and swallowing, initially enters the stomach where it is mixed and ground into small partsand where the first steps of digestion begin.

However, most of the digestion and absorption of nutrients takes place in the small intestines. Powerful enzymes and other digestive substances from the liver and pancreas break down food components (such as proteins, fats and carbohydrates) into smaller molecules that can be readily absorbed into the bloodstream and be used by the body for energy and to build or repair tissues.

The last part of the gastrointestinal tract is the colon (or large intestine). Here, water and minerals are absorbed into the bloodstream, and undigested matter and waste is eliminated as faeces.

An extremely wide range of disorders can affect the gastrointestinal tract. Some diseases occurring in other parts of the body can affect the gastrointestinal tract (e.g. hormonal disorders), but most commonly the underlying disease will involve the gastrointestinal tract itself. Gastrointestinal disorders generally impair a dog’s ability to digest and absorb nutrients, and many cause irritation or inflammation in the intestine as well.

The most common signs of disease are:

  • Diarrhoea
  • Vomiting

However, a variety of other signs may be seen such as:

  • Loss of appetite
  • Weight loss
  • Constipation
  • Excessive gas
  • Blood or mucus in the faeces

By examining your dog and finding out from you what has happened, your vet can often determine the underlying cause. However, in some cases, additional investigations are needed. In those cases, your veterinary surgeon may recommend a variety of different tests including:

  • Faecal analysis
  • Blood and urine tests
  • X-rays or ultrasound examinations
  • Endoscopy or possibly surgery to take biopsies

Depending on the cause and severity of your dog’s problem, treatment can range from simple dietary management (such as withholding food for a short period and then feeding a special diet), to a combination of dietary therapy with medication, or even abdominal surgery.

Since most gastrointestinal disorders interfere with the complex process of food digestion, diet has a major role in therapy, in minimising the impact of the disease and in supporting recovery.


One of the main reasons dogs with gastrointestinal disease get diarrhoea, flatulence and weight loss is incomplete or poor digestion and absorption of nutrients from the food. This can cause direct irritation to the intestine, and can also result in abnormal bacterial proliferation.
