Lessening scent: Bac to Nature do a spray which I am told is good. I have always used Sherleys deoderant Tablets (made of chlorophyl). I understand Johnsons also do these. I think they work, as when I have used them my bitches have attracted no notice of passing dogs, obviously I wouldn't stop and let them sniff :)
Some bitches can become a bit waspish before a first season especially. The first season is often not as long as normal, but don't count on this, always assume 3 weeks, and don't let her alone near a male dog for an extra week!
The amount of bleeding can be very variable, some staying scrupulously clean, with only a little found on bedding, some can be rather obvious, and not attend to cleaning very well.
You will normally find that a few weeks before the season your bitch is likely to squat a lot, doing a little here and a little there, in order to advertise her impending condition to potential suitors. When I want to be sure of knowing exactly when they come in, I will dab at the vulva every morning to detect the blood!
