Adult mixed-breed dogs (n = 5) and cats (n = 4) with normal renal function were fed low-sodium and high-sodium diets while being provided with free access to water, and blood pressure and water intake were examined. When the animals were fed a high-sodium diet after acclimation to a low-sodium diet, water intake increased significantly in both dogs and cats and then decreased significantly when the low-sodium diet was reinstituted (p 0.05). Blood pressure showed no significant change in either animal group throughout the study period, except that one dog showed increases in overall blood pressure levels by 10% during the high-salt diet. These results indicate that a short-term high-sodium diet has no effect on blood pressure in dogs and cats with normal renal function provided free access to water is provided.
