Question
One reason sometimes given on BARF lists for the safety of raw diets is that dogs have higher stomach acid than people, so that more bacteria are killed.
Answer
Amazing how most 'BARFers' try to rewrite biology to fit their agenda!!
An extreme pH is necessary to kill microbes. Most microbes we're concerned with thrive in a pH between 6 and 7.
On an empty stomach, the pH is closer to 1 or less regardless of species. pH is a relative concentration of H ions hence total amount produced is irrelevant. The pH of a stable solution is not time or volume dependent.
The actual stomach pH taken at any point in time when food is present will vary considerably depending on where in the stomach, the type of food present and when in the digestion process the measurement is taken. This is the same in dogs as it is in people. Dogs and cats (in general) eat higher animal protein meals than most people. Meals with more animal protein generally produce a greater acid load and will have a lower gastric pH. People who eat a high protein meal will also have a lower gastric pH compared to when they eat a totally vegetable meal.
The pH is near 1 in the stomach of most species for basically two reasons: kill any living organisms and digest protein. Peptidases secreted by the gastric mucosa require a low pH for maximum activity. The final chyme pH leaving the stomach varies between 1-6 and leaves the stomach based upon final osmolarity and food particle size, which is directly dependent upon type of food, time and the presence of water. So some meals require more time than other meal types. Obviously, it is not a foolproof system against microbes, because all mammalian species get bacterial and viral enteritis
The above is from petDIETS.com.
That means that the ph level varies and only drops to 1 when eating something such as meat.
Another website suggested testing as your dog's ph should be 6 or 7 before a meal.
Causes of death for a wolf can be parasitic infection ravaging the immune system, starvation, predation (ranchers, semis, other animals), malnutrition. Yes, they survive but it is not because they eat raw meat, it is because they eat what they can find, whether it is ultimately good for them or not. They have been known to eat evil grains and plant matter in the stomach of a kill from time to time, though there are people who say they don't need it or get benefit from it. That doesn't stop them from eating it, or berries, or anything else they can scavenge. The lifespan runs from 4 to 8 years, averaging 5 to 7. Yes, the raw meat sustains them but that doesn't mean that their diet is balanced. Because an animal has lived long enough to produce another generation doesn't mean that its diet was balanced.
OTOH, several people here have had good results feeding their dogs raw + carbohydrates.
