How long do dog menstruation cycles usually last, and should I be worried if it’s going on longer than expected?

I've noticed that my dog's menstruation cycle seems to be lasting longer than what I remember from her last one. She started a couple of weeks ago and I’m beginning to worry if this extended duration is normal. Can you tell me how long a typical cycle should last and if there's a point where I should be concerned enough to consult a vet?

Answer

It's normal to be concerned if your dog's heat cycle seems longer than usual. Typically, a dog's heat cycle lasts about 2 to 4 weeks, and if it's extended, it might be worth checking with a vet.

  • A typical dog's heat cycle lasts around 2 to 4 weeks.
  • Any cycle that extends beyond 4 weeks may require veterinary attention.
  • Watch for additional symptoms like unusual swelling, excessive discharge, or behavioral changes.

Dogs usually go through a heat cycle twice a year, and each cycle can vary in duration. If your dog's cycle is abnormally long, it might indicate an underlying issue such as a hormonal imbalance or infection. Monitoring her overall health and behavior can help identify if there's a cause for concern.

If you’re unsure or your pet’s symptoms are getting worse, book a consultation with a licensed vet at Dial A Vet for just $49 AUD.
