It all depends on the size of the dog. Contact a veterinarian.
First, there is no such critter as a "tea cup" anything. There are animals, primarily dogs, that are bred for smaller sizes. Now, I would feed the Chihuahua 2 times a day once in the morning and at night.
5 times a day
three times
You should feed them every two days
Two times a day.

two
feed the dog 2 times a day
Once or twice a day

I feed my cat one time per day in the morning
1 time a day
