I have a very, very deep respect for knowledgeable breeders ... after all, if not for Ava we wouldn't have our precious Toto! We signed a spay/neuter contract that was totally unnecessary because we made that decision before we ever found her!
We had to wait until she was 8 months for her to reach the 2 lbs. she needed to be for a safe spay. I don't believe there's a pup on the face of this earth that would be worth risking the life of our baby!
Besides ... like I have said before ... "I don't know nuthin' 'bout birthin' no babies" and I have no desire to do it. I believe it should be left up to the reputable breeders.
[BTW ... this is no reflection on new breeders who want to breed healthy pups .... we all had to start somewhere and I admire anyone who aspires to some day be a reputable breeder.]
