When a female dog is ready to mate, she exhibits several behavioral and physical changes indicating she is in heat (estrus). These signs can vary in intensity from dog to dog.
Here's a breakdown of the typical behaviors:
- Increased Urination: She will often urinate more frequently, leaving scent markings to attract male dogs. This scent contains pheromones that signal her readiness to mate.
- Changes in Behavior: These can include:
- Clinginess: She may become more affectionate and seek more attention from her owner.
- Restlessness/Agitation: Conversely, some female dogs may become restless, anxious, or even irritable.
- Playfulness: An increase in playful behavior can also be seen.
- Flagging: She will move her tail to the side when approached, particularly by a male dog, exposing her vulva.
- Physical Changes: These are generally more noticeable.
- Swollen Vulva: The vulva becomes noticeably enlarged.
- Vaginal Discharge: A bloody vaginal discharge is common at the beginning of the heat cycle, typically becoming lighter and more straw-colored as she becomes more receptive to mating.
Keep in mind that the intensity and duration of these signs can vary between individual dogs and breeds. It is important to be observant of your dog's behavior if you're concerned about a potential heat cycle or unintended pregnancy.
