heet cycle

Question
is there any way to very the time a female cocker comes into heet.  

Answer
Please don't breed your cocker unless you're a professional breeder and really know what you're doing.

The answer to your question is "no" and the question itself tells me you're a "backyard breeder" and I wish there was some legal way to stop you from damaging this wonderful breed.

If I'm wrong, I certainly apologize and if I'm not wrong then you should be totally ashamed of yourself.
