A gastric torsion in your dog

It is one of the biggest nightmares for every large dog owner: gastric torsion. This dangerous condition—also known as gastric dilatation-volvulus or stomach twisting—is very painful for dogs and can even be fatal if not treated in time. In this blog, we will take a closer look at what gastric torsion entails, what the causes are, how to recognize the symptoms, and what you can do to reduce the risk of gastric torsion in a dog.

What is gastric torsion?

Gastric torsion occurs when the stomach twists around its axis. This twisting causes the stomach to become blocked. As a result, blood vessels are pinched, which lowers blood pressure and heart function. This means the body receives too little oxygen.

Because the stomach is blocked, no air can escape. This causes the stomach to fill with gas, making it expand and become increasingly swollen. The enlarged stomach disrupts breathing and circulation, which further reduces oxygen supply to the tissues. Due to the lack of oxygen, vital organs are damaged, and ultimately, this will cause the animal to die.

What causes gastric torsion?

The exact cause of gastric torsion is unknown. However, several factors have been identified that may increase the risk of gastric torsion:

  • Dogs of large breeds and dogs with a deep chest have a higher chance of developing gastric torsion.
  • Genetic predisposition: if a first-degree relative of the dog has had gastric torsion in the past, the risk of developing it is greater.
  • Dogs that are very active or jump around a lot shortly before or after eating have a higher risk of gastric torsion.
  • Dogs with an aggressive or anxious temperament, who experience more stress, are at greater risk of gastric torsion.
  • Dogs that have previously had gastrointestinal problems are more likely to develop gastric torsion.
  • Dogs fed a large amount of food once a day have a higher risk of gastric torsion than dogs fed 3 or 4 times a day.
  • Dogs that eat rapidly are more at risk of gastric torsion. Eating quickly causes a lot of air to enter the stomach, which can lead to gastric dilatation and thus increases the chance of gastric torsion.

 

Symptoms of a gastric torsion

It is very important that you quickly recognize a gastric torsion in your dog. A dog with a gastric torsion can be identified by a swollen and hard abdomen (especially on the left side, just behind the ribs). In addition, the dog will try to vomit without anything coming up (dry retching), drool a lot, and become lethargic. A gastric torsion is very painful for the dog. Pain symptoms such as whining or howling, rapid breathing, and adopting a tense posture are also part of the symptoms of a gastric torsion.

Treatment of a gastric torsion

A gastric torsion is a life-threatening situation and is always an emergency! Therefore, contact the veterinarian immediately if you recognize the symptoms in your dog.

The treatment of a gastric torsion always starts with stabilizing the dog. This is done by, for example, administering oxygen and raising blood pressure with medication. Next, it is important to relieve the pressure from the stomach. This is done by inserting a tube into the esophagus or by releasing gas from the stomach with a thick needle. In most cases, surgery is necessary. During this surgery, the stomach is rotated back to its normal position and attached to the abdominal wall. This is called gastropexy. This reduces the dog's chance of developing another gastric torsion. A dog that has had a gastric torsion once has about an 80% chance of getting it again.

How can you prevent a gastric torsion in dogs?

There is much speculation about whether the type of food (kibble (pressed or extruded), canned food, or fresh meat) influences the development of a gastric torsion. However, these recommendations are not scientifically proven. Unfortunately, the chance of a dog developing a gastric torsion can never be completely prevented. However, there are some things you can consider to reduce the risk of developing a gastric torsion:

  • Adjust the kibble size of the food to the size of the dog. This encourages the dog to chew the kibble well and eat more slowly.
  • Avoid activity 1 hour before and 2 hours after eating. So do not walk the dog after eating and do not give him his full bowl right after a walk.
  • Give several small meals per day instead of one or two large meals.
  • If the dog gulps down food, get an anti-gulping bowl so the dog eats more calmly and swallows less air during eating.

Besides feeding the dog properly, it is also advised not to breed from parent dogs that have previously had a gastric torsion. Genetic predisposition is an important factor in whether a dog might develop a gastric torsion or not.
