Dogs often pack up and act aggressively when female dogs in the community are in heat. Recognizing the signs of a dog in heat and restricting contact with other dogs can prevent or decrease many dangerous dog encounters! When it isn’t possible to have a dog spayed, managing her movement and contacts when she is in heat is best.

First, Recognize the signs of a dog in heat.

  • Swollen vulva and vaginal discharge
  • Increased aggression, especially towards often unspayed females
  • Increased interest in roaming or getting out of the yard

Second, take caution in public.

  • Be sure to have her on a secure leash and keep away from other dogs
  • Even contact with spayed or neutered dogs can lead to hormone-related aggression

Third, Monitor.

  • When a dog is in heat, she will do almost anything to find a mate and breed
  • It is important to keep her separate from other dogs at all times while in heat

Fourth, Separate and secure.

  • A dog in heat can attract male dogs from over 1 km away
  • Keep her in a secure enclosure where she cannot get out and other dogs cannot get in

Fifth, Track and prepare for heat cycles.

  • Dogs can go into heat as young as 6 months old
  • Most dogs’ heat cycles last 1-3 weeks
  • Smaller dogs cycle every 3-4 months
  • Large breed dogs cycle every 6-12 months

Sixth, Spay to permanently prevent pregnancy.

  • There are many benefits to spaying your dog beyond preventing pregnancy, such as reduced risk of cancer and infections
  • Talk to your veterinarian about the best options for you and your dog
