Why is my dog having white discharge from her anus when pooping?

My dog has a white discharge coming out of her anus. She had her anal glands expressed last week because that's what I originally thought the problem was. Last week before they were expressed they were hurting her, but now she does not act as if they are hurting. The white discharge appears when she has to poop, and is gone after she poops. Is the white discharge normal?

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.

Thank you for submitting your question regarding Luna. She could be expressing fluid from her anal glands. This is the normal way that a dog marks her scent. If this is not the case, then the discharge could be mucus from her colon. This is typically the result of inflammation. If it continues, you may want her veterinarian to evaluate a fecal sample to ensure there is not a problem. I hope this information helps!
