The amateur dog breeder should never breed Pomeranians, because of their tiny size. They almost always require lap breeding, Caesarian sections and have many other complications due to pregnancy and birth. Males that are not neutered can become aggressive. Since most Pomeranians have health problems with their eyes, skin, heart and skeletons, only the healthiest should ever breed no matter how cute they look. They are better off with quiet adults rather than a family with young children.
