Taste is a very subjective sense. The sense of taste is closely linked to the sense of smell and both work together to determine food preferences. Dogs do not tire of their food: A dog can eat a food it likes every day-which, in fact, is recommended.
The sense of taste depends on the taste buds present in the mucous membranes of the tongue, palate and pharynx. Dogs have about 12 times fewer of these taste sensors than do humans. The glossopharyngeal and lingual nerves originate in the taste buds and carry nerve signals to the brain. As with smell, this gustatory information arises from the interaction of chemical substances in food that are dissolved in the saliva and taste cells.
