Dog ate chocolate?

Bleeding anal glands.

Species: Dog
Breed: chocolate lab
Age: 8-11 years
My dog has been having blood drip from his rear. My vet has expressed his anal glands twice in the last three weeks and both times they were full of blood. There was no puss or brown material it was all red blood. She told me she has never seen anything like it before. He is still eating and having normal bowel movements. He has been on antibiotics for a few weeks now and they seem to not have any effect. Have you ever seen anything like this?


Online vet, Dr. Marie

Dr. Marie replied:

I have seen a couple of anal sac abscesses that looked like pure blood coming from the anal glands.

However, though, your situation reminds me of one case I had where the supposedly infected gland was just pouring blood. It turned out that this dog had a tumor in its anal gland.

If things are not improving your vet may recommend doing a biopsy of the gland.

Dr. Marie.
