8 spots are made available for each litter prior to birth, 4 males and 4 females. Each litter may have a different number of puppies, comprised of different numbers of each sex. Until the litter is born we will assume 4 males and 4 females to each litter.

The reservation list will appear like this:

Male #1 RESERVED
Male #2 Available
Male #3 Available
Male #4 Available

Female #1 RESERVED
Female #2 Available
Female #3 Available
Female #4 Available

Once the litter is born and we have an official count of puppies and number of each sex, the reservation list will be updated to reflect those numbers.
Anyone who reserved a puppy of which there are not enough of that sex will be given the option of choosing a puppy of the opposite sex, or being placed at the top of the reservation list for the next litter.
Any deposit already paid would be applied to reserving a puppy from the next litter.
