BLOAT BECOMES GASTRIC TORSION

Some of you are smiling, thinking your dog has no problem passing gas!  That is when his stomach is in the normal position, not twisted as in bloat. Passing gas indicates fermentation so you will definitely want to keep reading because if passing gas is frequent, you need to change dog food and/or adjust his diet to prevent fermentation.

Strenuous exercise after eating may set off a chain reaction leading to a fatal episode of gastric torsion. Older dogs, those recovering from illness, a change in dog food or over-eating; many situations can precipitate an emergency bloat situation.

Why is gastric torsion so serious?

It is more difficult for a dog to pass gas and when the stomach twists, it is impossible to relieve the increasing pressure. Torsion sets off an inevitable sequence of events that is always fatal. It can happen so quickly that every owner of a breed over 50 pounds or one with excessive skin or one that is “out of condition” or elderly, or one that has gotten in to strange foodstuffs (farm dogs for example) or one that chronically drinks a lot of water - in other words, all dog owners need to know what bloat is and how to recognize simple bloat before it becomes gastric torsion, which be fatal within an hour!

What causes bloat?

Some foods contain saponins, a plant or marine-derived "sudsy" substance which "may aid digestion and/or nutrient absorption."  They should NOT be in any premium brand of dog food.

Humans can pass gas in either direction because the stomach is in upright position.  A dog's stomach is suspended like a hammock and the weight of an overfull stomach makes it more difficult to pass gas in either direction.  When the canine stomach becomes distended, it put pressure on other organs, including the diaphragm. As he becomes more uncomfortable, a dog swallows repeatedly, adding more air and saliva to the stomach and he will often begin to drink more water which adds more weight and hastens the twisting of the ever-enlarging stomach. When the stomach rotates, it effectively shuts off the blood supply. The tissues begin to die and the end is near because unless surgery is done very quickly, the damage is too great for recovery. Even with fairly prompt treatment, there is an average 35% death rate.

Should I worry that my dog will bloat?

Male dogs are more likely to be affected and there is speculation that an excessive skin-to-frame relationship can precipitate calcium and other chemical imbalances that bring on bloat. Dogs that are fed only once a day and particularly if given foods containing corn, soy or other gas producing grains are more likely to bloat. In the wild, wolves, coyotes, and especially the big cats, can gorge until they appear “about to burst” with no ill effects because they eat meat and they sleep for hours during digestion.

Some breeds such as Great Danes, Saint Bernards, Akitas, Bloodhounds, are more susceptible to gastric torsion according to Purdue University Vet School.  Age, condition, certain behavior patterns, and physical features can also increase the odds of bloat. Active breeds with a deep chest and tucked up stomach such as Weimaraners, Irish and Gordon Setters and Standard Poodles are considered at risk. Basset Hounds are right up there, possibly because of the long suspension system for the stomach and the excessive skin.

Can I prevent gastric torsion?

One of the most common mistakes leading to bloat involves exercise with a full stomach, particularly during mating. Never attempt a mating during the heat of the day. Never use a stud dog when he's just been fed. A  stud dog with a full belly full of food or water is not at his best anyway but more important, the likelihood of gastric torsion brought on by the mating dance is a very real danger for dog or bitch.

Any form of hard exercise before or after large amounts of food or water is likely to cause bloat.

Dogs that have bloated and survived need special diets. Your vet will take care of that. To prevent a first occurrence, practice common sense and feed wisely, bearing in mind that no breed is immune to gastric torsion.  If possible, feed smaller meals, twice a day. There is speculation that elevated feeding bowls reduce the incidence of bloat but there is adamant opposition to that theory. Dogs normally eat from ground level, often in a prone position as in ripping meat from bones, so until there is solid proof that elevating the food bowl is of value, I would advise feeding from the floor.

Some chew-bones promote air swallowing. Some dogs are gulpers when they eat and while this is normal for the canine, but if your dog seems to swallow air while ingesting food, put large washable pebbles or decorative rocks in his food bowl. Anything to slow him down. Remove any other dog that may cause him to eat too fast. Re-read the above about excessive water consumption, exercise, etc.

What Are Symptoms Of Bloat?

In the beginning, there develops a combination of symptoms that include signs of discomfort, restlessness, a “worried” expression, wanting to go out but not really doing anything when you take him to relieve himself.

Symptoms may progress to aimless pacing, panting which will become rapid and shallow. He will swallow, salivate, and try to vomit but it will be futile if the stomach has already torsioned.  By the time you see that his stomach is visibly increasing in size, he is in serious trouble. His gums may become pale, heart rate becomes rapid and he will progress into shock if the stomach has already twisted. 

The expression is unforgettable.  Some call a glassy-eyed look but other owners describe it as a "helpless, stricken" look, as though the dog somehow knows he is dying.  It isn't the pained look a dog gets from a broken leg.  I hope you never see that fatalistic expression.

What should I do if my dog is bloating?

You may want to try emergency measures before leaving for the vet because depending on traffic, distance, and his condition when discovered, you may arrive too late.

If you have a dog that would be considered at risk, you should have on hand one of the over-the-counter rapid gas reducers such as Gas X, any product with simethicone that breaks up the bubbles. If unsure, ask your vet. Administer according to directions and based on the size of the dog.

Then stand the dog upright and burp just as you would a baby. If you have someone to help hold him, so much the better. If not, place his front feet up on the sofa, a chair, your chest, whatever is reasonably comfortable for him. Begin to “burp” him starting low on either side of the belly and working your way up the rib cage. If he belches in your face, thank God and keep burping him. You may have to let him down for a minute to relieve pressure on his back legs but continue to burp until he seems comfortable and no more gas is passing.

If he does not pass gas, it is because the tablet isn’t working, you are not burping properly, or the stomach has twisted. In either case, stop what you are doing and rush him to the vet. If possible, have someone call ahead or use your cell phone. This is an emergency situation and any vet should be prepared to take him straight in to surgery.

We hope you never need this information. If you suspect your dog may be at risk, talk to your Vet before there is an emergency. A change in diet, feeding schedule and habits can prevent bloat.
