What is Canine Estrus?

Duration of Heat After Bleeding Ends

The bleeding phase primarily occurs during proestrus. Once bleeding diminishes or stops, the dog enters estrus, the true "heat" phase. This phase lasts approximately 5 to 9 days, during which the female is fertile and will accept mating.

Key Points:

• Bleeding typically lasts 7 to 10 days but can vary.
• After bleeding ends, the female’s vulva remains swollen.
• Behavioral changes such as increased affection or restlessness are common.
• Ovulation usually occurs within the first few days of estrus.

Behavioral Signs During Estrus

• Tail flagging (holding the tail to the side)
• Increased urination to mark territory
• Attracting male dogs
• Changes in appetite and activity levels

Care Tips During Heat

• Provide extra attention and comfort.
• Prevent unwanted mating by supervising outdoor activities.
• Maintain hygiene to prevent infections.
