How many puppies can a 4 year old teacup yorkie terrier have?

A 4-year-old teacup Yorkie can typically have one to three puppies per litter, though the average is usually around two. Due to their small size, teacup Yorkies are at a higher risk during pregnancy and delivery, so it's important for breeders to monitor their health closely. It's also essential to consider the health of both the mother and the potential puppies when planning a breeding.
