My dog has bright red blood on her bum and stool. Is it anal cancer?

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.

It sounds like your dog has a rectal polyp. This fleshy bit of tissue is likely what is causing the blood you are seeing in the stool. If the treatment your vet prescribed is not working Jaz may need surgery to remove the polyp. Some vets feel comfortable performing this surgery while others may refer you to a specialist for surgery or endoscopy. I would recommend speaking with your vet about a possible referral to have the polyp removed.

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.

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.

Oh my. Poor Ben. Bleeding inside the rectum is not a good sign unfortunately. A mass inside the rectum is a feasible possibility considering the fact that anal gland don’t usually bleed out the rectum in this fashion because a small duct is the only opening to the rectum from the anal glands. It is more likely the bleeding is coming from the colon and a bleeding ulcerated mass has to be seriously considered. Your vet should be able to do a rectal exam and/or endoscopy to look for a possible mass and help you with your decision making moving forward. I hope everything turns out ok for your pet Ben. Best wishes and take care.

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.

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.
