Why is my dog bleeding from her anus with a red bulge after pooping?

Hello. Dark blood like this at the anus may indicate a polyp or tumor in the rectum or anal area. It can sometimes be difficult to feel this with a finger during a recital exam. but if it is close enough to the anal opening, it might be accessible. Aside from a bleeding mass, other causes can be chronic colitis or anal sacs infections. Your vet may need to sedate him to do a more thorough rectal digital exam, or consider using a scope to look up in there to see if there is anything. Best of luck.

She may have an infected anal sac or the mucous membrane of the rectum may be injured or she may have a rectal tumor. If the bleeding does not stop you will need to take her to a veterinarian or pet ER for an exam.

Poor Roscoe! It's not normal to bleed from the anus after bowel movements, and the thing you see sticking out of his anus could be a tumor, impacted and infected anal sac, or his rectum could be prolapsed. Roscoe could see a vet right away for this, and I would bring him into a vet ASAP to be examined so this can be treated.

Thanks for using Petco Pet Education Center, formerly Petcoach! There are a few things that can cause this such as parasites and in uncommon instances cancer such as lymphoma, among other possibilities. Your veterinarian would be able to examine her more closely and see what seems likely so that therapy can be started. Hopefully it is just a case of parasites as it is most of the time. Best of luck!

It is hard to tell for sure by the pictures, but my suspicion would be that it is either a perianal tumor that has bled, or potentially a ruptured anal sac abscess. I would highly encourage you to have her evaluated by your veterinarian as soon as possible. If it is an abscess then antibiotics will likely be needed. If it is a tumor then the veterinarian can discuss options with you. Often perianal tumors are benign. I think getting a diagnosis is the first step and then you can gather information and make decisions from there. Best of luck and thank you for using Pet Coach.

If they vet recommended spaying, I wondering if the bleeding is actually coming from her vulva. If it's definitely from her anus, she needs a rectal exam, abdominal x-rays, and then likely a colonocopy to look for the problem. I would be concerned about a cancerous growth.

Your dog may have an injury in his anus or rectum, or a polyp or he may have an impacted anal gland. I strongly recommend you take him to your veterinarian as an impacted or infected anal gland is very painful and needs to be evacuated, or lanced and flushed. Please take Loki to a veterinarian ASAP.
