Now now.

I'm sure the OP did a lot of research on lines, and selected the very very best bitch to complement her prospective stud's lines. I'm sure she didn't just get a bitch willy-nilly.

I'm also sure that she plans to have all the relevant health checks, has read up extensively on breeding, and is prepared for everything that may go wrong. I'm sure she is prepared, in the worst case scenario, to lose all the puppies, and/or the dam.

I'm sure she realises that as the breeder she is responsible for the future puppies FOR LIFE, and will insist on the puppies coming back to her if for any reason their owners don't want them.

I'm sure the only reason she is breeding is to improve the breed.
