Gastrointestinal Diseases in Dogs


Gastrointestinal diseases in dogs are common and are characterized by frequent vomiting followed by diarrhea. In mild cases, the stool simply becomes softer, while more severe cases may involve watery and bloody stools.

Gastrointestinal illnesses in dogs can for example be caused by a food allergy or by viruses and bacteria. When the dog vomits or has diarrhea, he loses a lot of fluid. In young or small dogs, this can quickly cause dehydration while larger or older dogs have less difficulty dealing with this water imbalance.

Various causes of gastrointestinal illnesses in dogs

Gastrointestinal illness can be caused by the simple fact that the dog has eaten something that it cannot tolerate, due to a food allergy, a foreign body, or bad quality food. Other types of gastrointestinal diseases in dogs are caused by different viruses or bacteria. The most well-known virus linked to gastrointestinal disorders is parvovirus. It is now possible to vaccinate dogs against parvovirus, which offers effective protection against the disease. However, the vaccine does not take full effect until a certain age, so the disease can more easily affect young puppies and, of course, dogs that have not been properly vaccinated.

How to deal with Vomiting

When your dog starts vomiting, it is advisable to completely stop feeding your canine friend for a few hours, before gradually reintroducing small portions of easily digestible food. However, it is important to hydrate the dog well, also in a limited way, through repeated smaller quantity of water. Most dogs want to drink a lot after vomiting, which can cause further vomiting. It should be borne in mind, however, that young puppies quickly lose their water balance as a result of vomiting and cannot go without food and water for longer periods of time.

How does nosocomial gastroenteritis spread?

Some highly contagious nosocomial infections are caused by infected dogs, and quickly turn into epidemics, as in the case of Parvovirus. In most cases, a dog will contract this virus, or come into contact with a bacterium that causes symptoms of gastroenteritis, through another animal, caregivers or medical equipment.

What are the risks associated with nosocomial gastroenteritis?

It all depends on what may have caused this nosocomial infection, as well as the dog’s general health. But the important thing to know is that organisms endemic to the hospital environment often have multiple drug resistance and can lead to outbreaks of infections. Let’s think of E. coli or Clostridium difficile which can also be transmitted to humans.

How to prevent nosocomial gastroenteritis?

Scientific studies have clearly shown that any nosocomial infection can be prevented by strict hygiene measures and a comprehensive biosecurity approach. Systematic and adequate hand washing has been shown to be effective in the hospital setting.

How to prevent nosocomial gastroenteritis
