What is the typical duration of a dog's estrus?

• A. Between 7-28 Days With A Mean Of 11 Days
• B. Exactly 15 Days
• C. Exactly 6 Days
• D. Between 4-21 Days With A Mean Of 9 Days

Answer: (D)

The duration of a dog’s estrus reflects how long the heat period lasts when a female is sexually receptive, and this length varies a lot between individual dogs. Clinically, estrus is commonly described as lasting around two weeks on average, but the actual duration can be shorter or longer. The most representative description is a range from about 4 to 21 days, with an average around 9 days. This captures dogs that have very short heats and those that extend into the latter part of the two-week window. Other options either propose a fixed length or give a range that’s less consistent with typical clinical observations, making them less accurate as a general summary.
