Teacup or small size puppies need extra care and nurturing. They eat special diets and must eat every 2 to 4 hours because they have small tummies and can’t hold much food. Since they do not eat much at a time, they must be crated or confined in a small area (4×4) most of the time until they are 6 to 8 months old to conserve their energy and give them a chance to grow up. We recommend 30 minutes to an hour of playing or being held and loved on then 2 to 3 hours of uninterrupted rest and sleeping time. Their food and water must be available to them at all times so that they can eat, drink and potty as their body needs to. They cannot sleep with you at night until they are older and can go over 6 hours without eating. Eating regularly day and night is critical for a tiny size dog until they are grown. Adhering strictly to this routine for playtime and rest time is a must for a tiny dog. Once mature, they are usually sturdy and healthy just like larger size dogs.
If you are a person with a busy schedule (away from home over 8 hrs. at a time), you may not be a candidate for a teacup size puppy. If you have someone who can check on it every few hours for you to see that it is eating and drinking as well as moving about normally you may do fine with it, but without some help, the puppy may not do well for you.
