The heat cycle in dogs, also known as the estrous cycle, is a recurring period when unspayed female dogs are fertile and able to get pregnant
. The duration of heat in dogs can vary, but it typically lasts for about 2 to 4 weeks
. Key points regarding the heat cycle in dogs:
- First heat Most dogs will experience their first heat cycle around 6 months of age, but this can vary depending on the breed, with smaller breeds sometimes starting as early as 4 months and larger breeds as late as 24 months
- Frequency Dogs typically go into heat twice a year, roughly every 6 months
. However, the time between cycles can range from 4 to 11 months, depending on the dog
. As dogs get older, the frequency of their heat cycles may become less regular
- Duration The entire heat cycle usually lasts 2 to 4 weeks
. During this period, the dog is fertile and can become pregnant
. The cycle consists of three phases: proestrus, estrus, and anestrus
- Bleeding Dogs in heat typically bleed for about 7 to 10 days, roughly half the duration of their cycle
. The amount of bleeding can vary among dogs
Spaying female dogs is a common and effective method for preventing unwanted pregnancies and reducing pet overpopulation
