This totally varies among bitches. I had one that didn't have her first heat cycle until she was 13 months old, but her littermate had her first at 6 months old.
As for the signs, they vary as well. Some bitches bleed first, but others will keep themselves so clean that you won't even notice that. Swelling of the vulva is usually a sign after the blood, but I have a girl that doesn't swell much at all, and another that swells early.
Does this mean you have decided to not show her anymore?
