What Happens If a Dog Is Bathed During Its Heat?

Bathing a dog during its period risks vaginal infection and chills. During heat, hormones lower immunity, making colds more likely. Also the vulva is swollen and sensitive, so bacteria may cause inflammation, even vaginal infection or pyometra.

Although the risk is small, it is best to bathe after heat ends. If the fur gets soiled, wipe it with a damp towel.
