What does it mean when a 'Dog is on Heat'?

Heat, or Estrus is a stage in female dogs when they are more receptive to mating.  

During heat periods, the vulva gets swollen and blood drops from the vulva. 

There are three stages of heat

  • Pro-Estrus
  • Estrus
  • An-Estrus
A dog comes on heat twice a year, though this varies depending on the individual dog and health conditions.
