Gastric Dilatation-Volvulus

(Bloat)

Owners of large or giant breed dogs should be aware of a stomach condition termed “bloat.” Bloat can occur when the dog’s stomach fills with air, food and fluid. It varies from “simple bloat”- when the stomach fills with air, but the dog can still expel it, to “gastric torsion” - when the stomach rotates closing off the openings and not allowing air to escape. Gastric torsion is a true surgical emergency. Without emergency surgery to untwist the stomach and restore normal circulation the condition is invariably rapidly fatal.

The signs of bloat include a suddenly protruding abdomen, retching, dry heaves, increased drooling, intense anxiety, and depression or weakness. Often these dogs will be breathing rapidly and be reluctant to lie down. If you notice any of these signs and suspect your dog may be bloating, contact your veterinarian immediately.

The exact cause of bloat is unknown, but it is generally believed that when a high risk dog eats a large meal followed by vigorous exercise the stomach can twist. The exercise causes a rapid mixing of food and water in the stomach resulting in gas and an increased tendency for stomach rotation.

A word of caution: although large breed dogs appear to be more prone to bloat, other breeds such as dachshunds and basset hounds can also be affected. Having a deep chest is a risk factor.

The following suggestions can reduce your pet’s risk of bloating:

1. Feed your dog 2 to 3 times a day, rather than a single large meal.

2. Schedule feeding times when someone will be home to observe

the dog’s behavior after the meal.

3. Do not allow your pet to exercise heavily after a meal.

4. Water should be available at all times, but should be limited

after meals if the dog likes to drink excessive amounts.

5. Be aware of the signs of bloat.
