Re: [PyrNet-L] all-in-one worm/flea control preparations

Well, I haven't heard that one. The flea control product in Sentinel and 
Program works by rendering the adult fleas sterile. It is not effective 
against flea eggs. After a flea bites the animal, the flea becomes sterile 
and does not produce more fleas. As far as making the dog sterile, well that 
sounds like urban legend to me, but I will see what I can find out. We have a 
few clients who are breeders who use sentinel or program, and I do not know 
of any fertility problems in their animals.
