Choosing the gender of your puppy - Male or Female?
It really comes down to personal preference but there are some key factors to consider before making your final decision.

In other breeds there is a decided difference in size, coat and temperament between the two sexes. In Japanese Spitz there really is little difference between a male and a female, the Japanese Spitz are just as affectionate,  lively and fluffy no matter the sex. So much depends upon the individual pup that you should place more emphasis on the temperament of the puppy rather than on its sex.

If you plan to have your puppy spayed or neutered before it reaches sexual maturity, choosing which sex to buy appears less significant.
