It also disables bacteria and other microorganisms that may have been eaten during the meal. Most pet parents don’t give much thought to their dogs’ stomach – unless there’s tummy trouble. How the stomach works isn’t a particularly glamorous or trendy topic – unless you’re into anatomy, physiology or nutrition.
A. The Raw Meals we stock from Natures Menu are ready-made raw meals for cats and dogs that comply with the guidelines for a complete and balanced pet food. We can also order in any of the Natures Menu just minces though for you to create raw meals for your pet in your own kitchen. When meat is rotted in certain conditions where no bad bacteria can get established, it can be, and in some cultures is consumed by humans. Some researchers suggest there are about 120 thousand types of good bacteria and only about 4 thousand bad ones.
In healthy upper digestive systems, the stomach’s sphincter valve closes to prevent the digestive fluids from refluxing upward. However, the fluids seem to pass this sphincter when the acids residing in the stomach become too great, which is usually caused by dietary influenced gastritis.
It also typically grows under microaerobic conditions at 37°C which is about human body temperature . The nucleoid material and ribosomes exist in the dense cytoplasm and an electron-lucent area is located in the terminal regions. This region and the insertion site located near the flagella is a “polar membrane”; it is an additional electron-dense band below the plasmic membrane while linked to it.
With the delayed gastric emptying effect, any bacteria that do survive are also able to grow up into much larger numbers, and this effect is continued in the large bowel, with further fermentation of the plant fibre, and a delay in overall gut transit time (up to 24 hrs cf 12 hrs) – this can also result in constipation from excessive water reabsorption, or in loose stools from the over production of short chain fatty acids in the colon. They may experience a gastro-intestinal upset when the bacterial load of the ingested food runs riot in the alkaline stomach environment. Gastric acidity is needed to sterilise ingested pathogens. Processed pet foods are often contaminated with salmonella and mycotoxins – the gastric acidity is a first line of defence, so dogs and cats with reduced acidity are vulnerable.
And the body requires a healthy population of good bacteria to mount a strong immune response. Eating this rotted meat is one way of acquiring the good bacteria, even though most is destroyed by the low stomach acid pH. It is not the actual bacteria that make humans sick from rotten meat. It is the ingestion of toxins previously produced by the bacteria in the rotting meat and then absorbed into the blood stream causing vomiting and diarrhoea as well as fever and weakness.
Partially digested proteins, caffeine, and rising pH stimulate the release of gastrin from enteroendocrine G cells, which in turn induces parietal cells to increase their production of HCl, which is needed to create an acidic environment for the conversion of pepsinogen to pepsin, and protein digestion. Additionally, the release of gastrin activates vigorous smooth muscle contractions. However, it should be noted that the stomach does have a natural means of avoiding excessive acid secretion and potential heartburn.
The presence of a helicobacter infection means an animal’s innate GI defenses have been lost and local bacteria have taken advantage of the situation. It could be that too many antacids or H2 blockers were given.

- We conducted a systematic review to test the hypothesis that a key role of the vertebrate stomach is to maintain the gut microbial community by filtering out novel microbial taxa before they pass into the intestines.
- It vigorously churns food.
- Usually, it’s just annoying.
- Foods heavy in carbohydrates empty fastest, followed by high-protein foods.
- pylori pathogenesis; it creates a pH-neutral microenvironment around the bacteria which is necessary for survival in the acidic stomach, pH 1.0-2.0.
Usually, it’s just annoying. GERD can, however, have serious consequences, including esophagitis and Barrett’s esophagus. Barrett’s esophagus is a condition that increases the likelihood of esophageal cancer. Great article but I think you have missed some very important points. My understanding is that the gastric pH of a kibble fed dog is no different from the gastric pH of a raw fed dog when the dog’s are not eating.
Pepsin is solely responsible for protein digestion, and lipase, which is only found in the stomach of carnivores (dogs and cats), begins digesting fats. Also known as gastroesophageal reflux disease (GERD), acid reflux disease is a chronic irritation of the lining of a person’s esophagus by stomach acid.
And in the case of Clostridium botulinum it causes flaccid paralysis. But the second half of your question where you ask if this is the reason that dogs can handle rottener meat than humans is more difficult to answer. Probably not very significant actually. The stronger acid definitely helps to digest raw bones but rotten meat is a different issue. The fact is that the actual bacteria causing the meat to go bad rarely survive either dog nor human stomach acid levels.
The primary hormone produced by stomach cells is gastrin, which controls acid secretion and stomach contractions. Gastrin stimulates the release of hydrochloric acid that, in turn, interacts with pepsinogen to activate pepsin and start the protein digesting process. The most numerous cells lining the inside of the stomach are mucous cells. These cells produce an alkaline, bicarbonate-rich mucus that coats, lubricates and protects the stomach lining.
We expect you to use your knowledge of your pet and your circumstances to determine, with the knowledge and input of your trusted veterinarian, whether any advice provided on this site is appropriate for your pet. The role of gastric acid in preventing foodborne disease and how bacteria overcome acid conditions . Because maintaining an acidic pH environment is costly, acidic stomachs should be present primarily in those cases where it is adaptive (or where it was adaptive in a recent ancestor). The cost of stomach acidity is twofold.
