Just to add when she stops bleeding this does not mean the season ahs finished, with most bitches it is actually the most fertile time(though some bleed throughout).
As has been said to be extra safe she must be kept away from any male dogs for 28 days from the first day of bleeding.
If you live in an area where you don't have uncontrolled loose dogs roaming the streets (we have an efficient Dog Warden) then you can still take her for lead walks on the streets, but do not take ther anywhere where dogs are likely or have a right to be loose, as the best trained dog will ignore it's owner and head straight for your girl, otherwise you will just have to keep her to the garden, but never leave her alone, and watch ehr even when she goes out for a pee.
