Who many puppies can tea cup dog have and does the mom have a good chance it will live after giving birth and what age is good to breed
Extremely important - of the two parents, the male MUST be the smaller. Unadvisable for the female to be too small - there's a good chance she won't survive.
There is no such thing as a teacup dog! That is just a poor nickname bad breeders use when they mate runts of the litter! They are typically unhealthy.
