My dog has an anal sac lump with discharge. What could it be?

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.

I am sorry to hear that! It may be that the infection is still going on - you may need a longer course of the antibiotic or perhaps a different one. I would recommend having them expressed again to see if there is still debris present. I would also want to double check and make sure there is not a mass present in the area:( You can ask for a biopsy to be done if the lump seems unrelated to the infection. I hope this helps and that it is nothing more than a persistent infection!

Sorry to hear that Honey isn't right. I would want to know if that vet only analyzed the discharge or actually obtained a needle aspirate of the mass itself. While analyzing the discharge is fine, it is not going to be as accurate or meaningful as obtaining a sample of the mass. The most effective way to find out what is happening would be removing the affected area and sending it out for a biopsy. If it is an abscess or some sort of cyst, it would be curative hopefully. If it ended up being malignant in some way, they may have to go back and remove the entire mammary chain. Mammary cancer would be pretty unusual but certainly not impossible for a four year old dog. Hope this helps.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. Based on the location, often times these tumors are benign in nature and are known as perianal adenomas though about 10% are malignant and again it could be really any other tumor type. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Hi, I am not sure when you first noticed this lump but it really needs to be checked over by a vet ASAP. It could be a cancerous lump, and the sooner it is diagnosed as such the better treatment and outcome for Nina. Adenocarcinomas in this area are very frequent and it is essential to have an early diagnosis. Hope this helps,

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. These could also be abscesses based on your description. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Saffie evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!
