My dog's period is late, but she's not pregnant. Is this normal?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 2 years and 1 month old

Why haven’t I seen my dog’s period? She is not pregnant, it’s been almost more then 3 months ago that she was due for her period to come.

Most pets have a menstrual cycle once every 4.5-8 months on average, and some breeds only have 1 cycle per year, like the Basenji. So it is normal if she is not on a routine once every 6 month rotation. Since she is a mixed breed, she may have the genetics for having a once yearly cycle.

She doesn't appear to be bloated or possibly pregnant, so she likely will skip this period. If you want to just make sure her overall health is ok, then routine bloodwork is recommended through your vet. Although she is likely just fine.

I wish you all the best with your pet Chloe. Take care!
