I cannot believe that this day has arrived - it only seems 5 minutes since we went to collect her as an 8 week old puppy.

She has not been 'herself' now for a couple of weeks - off her food, sulking around the house and occasional wee wee accidents on the kitchen floor.
This morning I noticed a spot of blood on her bed - her new one which I got from PAH at the weekend.

I have checked her vulva and there is blood around it.
A few questions:
Do I count this as day one of her season?
How long do I keep her away from any male residents in the area?
How long after today can she be spayed?
How long will she 'bleed' for?
Sorry for so many questions but I have never had a bitch in season before - Kiwi our old Weimaraner was spayed before her first season.
