The average life span is actually 10 to 14 years for a teacup or toy sized dog–actually longer than larger breeds of dogs! Generally speaking, it really depends on how you take care of the puppy. Our puppies do not come from a puppy mills/farms. All our puppies come from reputable breeders who specialize in each breed. Inbreeding or puppies from puppy mills/farms affects the quality of life and causes shorter lifespan of a puppy due to their environment and heredity. Our puppies are expected to live as long as other dogs in the same breed does.
