Many bitches go off their food, and being quiet and extra affectionate is normal too.
Remember walks on lead only where dog shave no business being allowed off lead.
No owner can be expected to control their male if your were to walk your bitch in a dog off lead area,a s they wouldn't know, and the temptation would be just to much to trust any male dogs obedience.
Also on average a season last 21 days, but bitches can be fertile and conceive after this time, so ti is best to be vigilant for another week.
