Puppies need several meals a day, while older dogs need one or two meals a day.
It is necessary to determine how much food keeps your adult dog that looks and feels best. Then decide how many meals a day. If you are concerned that they will gain weight, you need to be sure that you measure good food and not to provide snacks. Whether you feed your dog once or twice a day, he needs to leave food for as long as it takes to eat, eg. 10 minutes. Do not worry if your dog does not eat all at a particular time. They will learn to be.
Pregnant bitches and bitches who are breastfeeding need more meals a day, 3 to 4. They can be given vitamin and mineral supplements as recommended by your veterinarian.
Do not feed Chihuahua while you eat. Feeding at the table will turn your dog into a pain, to beg for food and embarrass you in front of guests.
