What is the difference between ignorance and apathy?

I don't know and I don't care.

I'm interested in adopting a flat-coat puppy.  How can I obtain information about breeders and litters?

The Flat-Coated Retriever Society of America (FCRSA) maintains a list of member breeders.  To obtain  a copy of it, go to the FCRSA web site and contact the Membership Secretary.
