An adult Chihuahua should be fed, on average, ¼ cup to ¾ cup of dry food per day. When adding canned food to the dog's diet, up to half of the dry food can be substituted with the same amount of canned food.
The exact amount of food a Chihuahua needs varies depending on the dog's weight and the quality of the food. Specific feeding guidelines are printed on the back of the bag or can. Puppies under eight weeks of age should be fed three to four times per day, while older dogs should be fed twice a day.
