Before you get a dog, it’s important that you’re ready to be a responsible dog owner. From getting a properly-sized dog crate to setting up puppy vet visits, there’s a lot of preparation to do. And if you have a female dog, that includes getting ready for your dog’s “periods” — or more accurately, her estrus cycles. Dogs don’t menstruate in the same way human females do.

Here’s everything you need to know about how to take care of your dog during her estrus cycle, including when dogs go into heat, how often, and products you’ll need to help manage the physical signs.

When Do Dogs Get Their ‘Period’ and How Often?

Female dogs typically reach sexual maturity around six months old and that’s when have their first “heat” or estrus cycle. During this stage, there’s an increase in estrogen levels, then a sharp decrease, and then her ovaries release eggs. Their estrus cycles typically last three weeks but can range between two and four.

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. It’s considered best practice to wait until your dog’s third heat to breed her. However, your vet can perform genetic testing and tell you when your dog is ready.

Dogs typically go into heat on average every six months, but this varies especially in the beginning. It can take some dogs around 18 to 24 months to develop a regular cycle. Small dogs usually go into heat more often — as much as three to four times a year. Large breeds such as Great Danes and St. Bernard might only go into heat once a year.

Dogs will continue to have cycles, but the length of time between estrus will increase as she gets older.

How to Tell if Your Dog is in Heat?

When your dog is in heat, there are both physical and behavioral signs. For example, she’ll typically urinate more than usual, and there will be a blood-tinged discharge and swollen vulva.

Your dog may also seem nervous, distracted, and be receptive to male dogs. She may initiate sexual contact such as raising her rear and deflecting her tail to one side, which is called ‘flagging.’ Your dog will likely actively court males dogs until the cycle is over.

The heat cycle lasts about three weeks. The discharge starts as frank blood and then gradually lighten to pinkish in color. A bitch can usually become pregnant around the end of the first week until after the second week, sometimes longer.
