1. What is heat?
Heat is more properly called the estrous cycle. During this cycle, female dogs may get pregnant. It's equivalent to human menstruation.
2. What are the symptoms?
Females bleed from the vagina sometimes with swelling of the vulva and increased urination. Don't expect bleeding comparable to a human female.
For small dogs, it's usually not much and you may need to pay close attention to your puppy to identify her first cycle. Other than the bleeding, the most noticeable symptom may be
male dogs hanging around your house.
