The MC in female dog is twice a year. The real MC cycle for dog is 6 months. They have a very long resting stage during one cycle. The time they are in heat(you will see behavior changes, swollen of vagina and bleeding in the first 10-14 days) is about 3-4 weeks and it happens at spring and fall quarter. Dandy's Doctor is right because the May, fifth in lunar calander is already during summer time, so female dog is not in heat any more. Of cause every female dog's cycle won't be at the same time. That's why male dog can get crazy for almost 2-3 months during spring/fall. In Taiwan, we do not have very significant different temperature during the four seasons of year especially in southern Taiwan, so the cycle for female dog will be more variaty. Sometimes you will see a female dog is in heat during winter time if the temperature is warm enough.
