There's a lot of overlap between the pH of
stomach acid in people and dogs. The pH [acid]
range in people is 1.5 to 3.5, where lower numbers

pH 1 is 10 times more acidic than pH 2.
That's because pH 1 is an acid concentration of
0.1 moles per liter, ['10 to the minus 1'] and pH
2 is an acid concentration of 0.01 moles per liter
['10 to the minus 2'].
