This does not sound too good to me. The puppies should all be priced the same, dogs and bitches. Some breeders will try to charge more for a particular sex. Is this man waiting to see what colour these puppies will be, and possibly charge more for one colour than another. How can you commit to have one of these puppies when you have no idea of the price. Also, good breeders normally wait until the puppies are a few weeks old, maybe 3-4 weeks, before allowing potential new owners to view the litter. Are the parents Health Tested ? Lots of questions being raised in my head.
