My dog has red, weepy lumps under her tail near her anus. What is it?

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!

If the lump is associated with one of the anal sacs (glands at about 4 and 8 o clock inside the anal sphincter) it could be an apocrine gland tumor. Apocrine glands are sweat glands. There are also other lumps that can occur in this area so it depends on if the lump is in the typical location for one of these glands. One thing that could be considered before surgery is a needle aspirate with cytology. We use this test commonly to try to diagnose lumps before surgery. It can be helpful to know what it is before surgery because if malignant some tests may be recommended before surgery and the surgery plan sometimes changes. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

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!

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.

This lump could be a cyst, an abscess, a lipoma, or a growth. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give Rosemary's vet a call to make her an appointment.
