Gastroenteritis can happen to dogs of any age and can have many causes, from nasty viruses to too many treats. Most cases are cured by adjusting what they eat for a few days, but severe cases are emergencies and require intensive care.

The digestive system is a long, curly tube that takes what we need from our food and excretes what is not useful. To achieve this, it needs close contact between the digestive cells and the food, as well as the help of many friendly bacteria. Anything that damages the digestive cells or the balance of friendly bacteria causes digestion to slow down and increases the build-up of gas and fluid. The body quickly tries to get rid of the problem. This causes the usual symptoms of gastroenteritis.
