How to determine heat in a stray dog? - in detail
Determining if a stray dog is in heat involves observing both physical and behavioral changes. Here are the key indicators:
-
Vaginal Discharge: The most obvious sign of heat in dogs is vaginal discharge, which can range from clear to blood-tinged or straw-colored. This discharge usually increases over the course of the heat cycle.
-
Swollen Vulva: The vulva may appear swollen and red due to increased blood flow. In some cases, it might also leak a small amount of fluid.
-
Behavioral Changes: Heat brings about significant behavioral changes in dogs:
- Increased Urination: The dog may urinate more frequently to mark her territory, attracting potential mates.
- Restlessness and Anxiety: She might become more restless or anxious, pacing around or whining.
- Mounting Behavior: Dogs in heat often mount other dogs, objects, or even people's legs, regardless of gender or species.
- Increased Affection: Some dogs may become more affectionate towards their owners during this time.
-
Tail Flagging: A common sign is tail flagging, where the dog raises her tail high and leaves it there for extended periods.
-
Attracting Males: In heat, female dogs release pheromones that attract male dogs from a considerable distance.
To accurately determine if a stray dog is in heat, observe her closely over several days, as the signs may not all be present at once and can vary throughout the cycle. If you notice these changes, it's essential to keep the dog away from unneutered males to prevent unwanted pregnancies.
