In three dogs equipped with an œsophagostomy and a gastric fistula, sham feeding caused a greater gastric secretory response than teasing with food. The acid output from the stomach in response to sham feeding and teasing was related to the duration of stimulation. The highest rates of acid secretion observed after sham feeding (mean 14·2 mEq/15 min.) were similar to the maximal rates during infusion of a gastrin extract (mean 15·4 mEq/15 min.) or histamine dihydrochloride (mean 14·4 mEq/15 min.).
