First of all, if a 3-month-old puppy has not been fully immunized, do not take it out to avoid contracting infectious diseases.
Secondly, Chihuahuas are very afraid of the cold. If the weather is slightly colder, they will not want to go out. Puppies are weak and cannot survive the winter easily. They must be kept warm. If it is too cold, it is better not to take them out.
Another thing is that the Chihuahua is still too young, and the puppies are very dependent and have a natural fear of the external environment. In addition, the mother dog is not around, and there is no older dog to teach it how to interact with its own kind, and it has no knowledge of new owners. To establish a completely trusting relationship, there is no offensive advantage. Outside, he is in a state of fear and isolation, and may also have a fear of being attacked. So it doesn't matter if it doesn't want to go out. Let's take it slow when it grows up.
Finally, I don’t know what you mean by independent play in the yard. Do you mean putting it in your own yard or in a community? The former is not good for the development of the puppy’s personality, so it is best to leave it at home; the latter is easy Causing the puppy to get lost or get hurt. If you are walking, be sure to wear a leash, pay attention to the temperature and safety, and don't force it too hard.
