Gastroenteritis is a Greek word that means inflammation of intestines and stomach. The signs for gastroenteritis are listlessness, vomiting, diarrhoea with blood, dehydration, lethargy, and shock. The cause of gastroenteritis is still unknown but there are several factors that trigger the development of gastroenteritis. These factors include stress, a sudden change in the diet, internal parasites, side effects of previous medications, diet intolerance, etc.
The puppy or adult dog with such signs should immediately see the veterinarian. The vet will make the diagnosis mostly by exclusion, i.e. by performing the test for the diseases that have similar symptoms. The other conditions with similar signs are parvovirus, ulcers, obstruction by foreign bodies, endoparasites, etc. In gastroenteritis, the RBCs count is higher that indicate the presence of gastroenteritis.
The vet after confirming the presence of gastroenteritis with administer I.V fluids, anti-nausea medications, antibiotics, administration of electrolytes, and will advise to keep the dog off feed. It is better to keep the puppy off feed for a minimum 12 hours and 24 hours for adult dogs.
