What's causing my dog's painful lump near her anus? Is it serious?

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.

It's a little difficult to tell from your picture alone - being able to examine and touch a lump in person makes it much easier to determine what it is. This could be a skin tumor, a small abscess or inflammatory nodule, or a lesion from something like contact hypersensitivity. I would recommend having this lump examined by your veterinarian since it looks red and possibly like there is discharge. If he is licking or chewing at the lump you should put an e-collar on him until you can see a veterinarian. They may know what it is after being able to examine it or may recommend taking an aspirate sample using a small needle to look for cells under the microscope.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is unlikely to be something of concern and most likely represents a region of pigmentation. However, I recommend you keep a close eye on it and if at some point it appears to become a mass, have him evaluated by a veterinarian for further assessment. Good luck and have a good night!

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!

Hello. From the photo that you provided, this looks like a growth that may be benign or malignant. It may also be a cyst. Your veterinarian can try to do a fine needle aspirate on the lump in order to determine if it is urgent to surgically remove it. As to whether the hot spot caused it…. that is not likely. Your pet may be licking or chewing at it and it may have had some part in causing the hotspot, but I cannot say for sure. Your next step should be trying to determine if surgery is needed to remove it. Your veterinarian can help you with that. Thank you.

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!

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! These look classic for perianal gland tumors. This is very common in intact dogs. The majority of these tumors are benign though a small percentage of them are malignant. I recommend you take him to your veterinarian for a test called a fine needle aspirate which can help distinguish these tumors from other more concerning tumors. If it truly is a perianal gland tumor, most of the time they resolve or greatly improved by neutering the dog as they are driven by hormones. If they are not bothering him, this may be enough. In cases when they are starting to bother the dog, you can also consider removal. Feel free to request a consult with me if wanting more information on the next steps. Good luck with your pup!
