Diarrhea is the frequent evacuation of watery stools. Vomiting is the forceful expulsion of stomach contents through the mouth.

What to do: - Remove all food and water.

- Check for signs of dehydration.

- If the diarrhea and/or vomiting continues or the pet acts ill, seek veterinary attention. Diarrhea and vomiting can quickly lead to serious fluid loss and electrolyte imbalance, especially in the very young and the very old.

- If no vomiting occurs for 6-8 hours, begin to give small amounts of clear liquids (water, Gatorade, Pedialyte, or other electrolyte solution) frequently. A rule of thumb is to give 1 teaspoon per pound of body weight every 2 or 3 hours throughout the day and night.

- Isolate the sick pet from other pets.

What NOT to do: - Do not medicate your pet without talking to your veterinarian.

- Do not allow the pet to eat or drink anything until there has been no vomiting for 6 to 8 hours.

Vomiting and diarrhea are associated with a host of problems which are referred to collectively as gastroenteritis. Some cases are quite severe (e.g., poisoning), and some are not (e.g., dietary indiscretion). If fever is present, infection may be a cause. Most infections which cause diarrhea and vomiting are contagious, so it is wise to assume that other pets might be vulnerable if they are exposed.

If your pet is not feeling well and has vomiting and/or diarrhea, he should see a veternarian.
