Q. Our female labadoodle is bleeding from her rear. Her stool is normal and she has been spaded over 2 years ago. What is causing this?
A. Your pet sounds like she has an inflamed or infected anal gland. This condition is very painful and makes it difficult to defecate or even move. Without treatment, the gland may rupture, causing a open wound on your pet's rear that will require wound care and antibiotics as well as some pain relief.
I recommend getting your pet seen by your vet. They will express the material from the anal glands (which is very smelly), clean her up and possibly start her on antibiotics. You can ask them to show you how to express the anal glands yourself at home so you can avoid impaction or infection in the future.
