From about six months old to through the rest of her life, a female dog will experience estrus, or heat, roughly every six months.
This is the period of time when she’s receptive to mating.
Do female dogs ever stop going into heat?
Female dogs cycle into heat on average every six months. But this can vary, especially in the beginning, so it’s a good idea to keep track. Your dog will continue to go into heat throughout her life, although the length of time between estrus will increase as she gets older.
Do female dogs ever stop bleeding?
After about 9-10 days, the bleeding will become more watery, or stop. It is at this time your female will, most likely, be at her most fertile. This proestrus stage can last as long as 20 days in some dogs. So the end of bleeding can be a more useful indicator of peak fertility.
How many years does a female dog go into heat?
When your female dog is receptive to mating, she is in a stage of her reproductive cycle known as being in “heat.” You can expect this to happen about twice a year beginning between six months to one year of age. Each time your dog goes into heat, the cycle will last about 21 to 28 days.
Can old dogs get their period?
While six months is the average age of a dog’s first heat, it can vary between dogs. Some dogs may go into heat at four months, but bigger dogs may be as old as two years before their first heat. Dogs will continue to have cycles, but the length of time between estrus will increase as she gets older.
