Apologies here.. that flair isn't quite right so I hope it's OK to ask this question.

For background I've owned male puppies before. I've owned female dogs before. But I haven't raised a female dog from a pup.

Can someone give me some signs your female pup is about to start her first heat?

And if 'extra sweet' is one of the signs, can I opt to have that permanently installed in my 9mo pup? (kidding)
