Why is my dog having white discharge from her anus when pooping?
The contents of the anal glands can be lots of different colors. Abnormal material is red (blood) or yellow/green (pus). If Luna isn't painful when defecating, licking her bottom a lot, or scooting her hind end on the ground, it sound like this is normal discharge. Anal glands are scent glands that normally empty with a bowel movement, so that's likely why you're seeing this tiny amount of discharge both shortly before and after she poops. The anal glands can become [infected or impacted](https://www.petcoach.co/article/anal-glands-sacs-impactions-infections-abscesses-in-dogs/), which can be quite painful. Keep an eye out for any changes in her behavior, appetite, energy level, and licking or scooting of the hind end, as these signs could indicate problems.
