How long dose a dog stay in heat.
You should consider your pet to be "in season" for 21 days: 7 days coming into heat, 7 days in heat, 7 days going out. Though conception is most likely during the middle 7 days, Mother Nature doesn't always follow the rules. Confine your pet for the entire 3 weeks
THE FEMALE WILL LET A MALE ON HER AFTER 10 DAYS OF COMING OUT OF HEAT SHE CAN GET PREGNANT1 REMEMBER THAT GIVE HER ONE MONTH AND + DAYS TO BE SAFE
A dog stays in heat for about 2 to 3 weeks and is in heat twice a year.
A female goes into heat every 6 months and stays in heat for 3 weeks!
If your dog is a "he"...then it's NEVER in heat!
about 3 weeks
