Bloat is a very serious health risk for many dogs, yet many dog owners know very little about it. According to the links below, it is the second leading killer of dogs, after cancer.
It is frequently reported that deep-chested dogs, such as German Shepherds, Great Danes, and Dobermans are particularly at risk.
This page provides links to information on bloat and summarizes some of the key points we found in the sites we researched. Although we have summarized information we found about possible symptoms, causes, methods of prevention, and breeds at risk, we cannot attest to the accuracy.
Please consult with your veterinarian for medical information.
If you believe your dog is experiencing bloat, please get your dog to a veterinarian immediately! Bloat can kill in less than an hour, so time is of the essence. Call your vet to alert them you're on your way with a suspected bloat case. Better to be safe than sorry!
The technical name for bloat is "Gastric Dilatation-Volvulus" ("GDV"). Bloating of the stomach is often related to swallowed air (although food and fluid can also be present). It usually happens when there's an abnormal accumulation of air, fluid, and/or foam in the stomach ("gastric dilatation"). Stress can be a significant contributing factor also.
Bloat can occur with or without "volvulus" (twisting). As the stomach swells, it may rotate 90 degrees to 360 degrees, twisting between its fixed attachments at the esophagus (food tube) and at the duodenum (the upper intestine). The twisting stomach traps air, food, and water in the stomach. The bloated stomach obstructs veins in the abdomen, leading to low blood pressure, shock, and damage to internal organs. The combined effect can quickly kill a dog.
Be prepared! Know in advance what you would do if your dog bloated.
If your regular vet doesn't have 24-hour emergency service, know which nearby vet you would use. Keep the phone number handy. | |
Always keep a product with simethicone on hand (e.g., Gas-X, Mylanta Gas (not regular Mylanta), etc.) in case your dog has gas. If you can reduce or slow the gas, you've probably bought yourself a little more time to get to a vet if your dog is bloating. |
This information is not intended to replace advice or guidance from veterinarians or other pet care professionals. It is simply being shared as an aid to assist you with your own research on this very serious problem.
Typical symptoms often include some (but not necessarily all) of the following, according to the links below. Unfortunately, from the onset of the first symptoms you have very little time (sometimes minutes, sometimes hours) to get immediate medical attention for your dog. Know your dog and know when it's not acting right.
Attempts to vomit (usually unsuccessful); may occur every 5-30 minutes
|

|||||||
Coughing | |||||||
Unproductive gagging | |||||||
Heavy salivating or drooling | |||||||

According to the links below, it is thought that the following may be the primary contributors to bloat. To calculate a dog's lifetime risk of bloat according to Purdue University's School of Veterinary Medicine, click here.

Some of the advice in the links below for reducing the chances of bloat are:
Avoid highly stressful situations. If you can't avoid them, try to minimize the stress as much as possible. Be extra watchful. Can be brought on by visits to the vet, dog shows, mating, whelping, boarding, new dog in household, change in routine, etc. |
|||||
Don't use an elevated food bowl | |||||
Don't exercise for at least an hour (longer if possible) before and especially after eating Particularly avoid vigorous exercise and don't permit your dog to roll over, which could cause the stomach to twist |
|||||
Don't permit rapid eating | |||||
Don't permit excessive, rapid drinking Especially a consideration on hot days |
|||||
Feed 2 or 3 meals daily, instead of just one | |||||
Don't give water one hour before or after a meal It dilutes the gastric juices necessary for proper digestion, which leads to gas production. |
|||||
Important! Always keep a product with simethicone (e.g., Gas-X, Mylanta Gas (not regular Mylanta), Phazyme, etc.) on hand to treat gas symptoms. Some recommend giving your dog simethicone immediately if your dog burps more than once or shows other signs of gas. Some report relief of gas symptoms with 1/2 tsp of nutmeg or the homeopathic remedy Nux moschata 30 |
|||||
Allow access to fresh water at all times, except before and after meals | |||||
Make meals a peaceful, stress-free time | |||||
When switching dog food, do so gradually (allow several weeks) | |||||
Feed a high-protein (>30%) diet, particularly of raw meat | |||||
Don't feed dry foods exclusively Whole, unprocessed foods are especially beneficial |
|||||
Avoid dry foods that contain...
|
|||||
If feeding dry food, select foods that contain...
|
|||||
Reduce carbohydrates as much as possible (e.g., typical in many commercial dog biscuits) | |||||
Avoid brewer's yeast, alfalfa, and soybean products | |||||
Promote an acidic environment in the intestine Some recommend 1-2 Tbs of Aloe Vera Gel or 1 Tbs of apple cider vinegar given right after each meal |
|||||
Promote "friendly" bacteria in the intestine, e.g. from "probiotics" such as supplemental acidophilus Avoids fermentation of carbohydrates, which can cause gas quickly. This is especially a concern when antibiotics are given since antibiotics tend to reduce levels of "friendly" bacteria. [Note: Probiotics should be given at least 2-4 hours apart from antibiotics so they won't be destroyed.] |
|||||
Consider adding an enzyme product to food to aid digestion (e.g., Prozyme) |
And perhaps most importantly, know your dog well so you'll know when your dog just isn't acting normally.
