Why is my dog licking a painful lump near her rear when walking?

This behavior in Brownie can be indicative of an impacted anal sac, and the lump next to his anus indicates that as well. The anal sac will need to be expressed if it's impacted, so I would take him into the vet now during normal business hours. It's important to have it expressed before it ruptures.

I am afraid I cannot see a lump on this photo, however if you can feel a lump near the anus it is likely a full or impacted anal sac. *You may need to take your dog to a vet to have it expressed, if he is bothered by it. Usually dogs start scooting on the floor when they have a bothersome anal sac.

I recommend to get Lilly examined. That could be an anal gland abscess or an infection. Have her examined today and keep her from licking or traumatizing the area. I hope this helps and please feel free to post any additional questions.

It looks like Betsy has a skin infection. If it feels like there is a lump underneath, it could indicate a skin tumor that now has a secondary infection. I would recommend to take her in for an exam. In the mean time, make her wear an Elizabethan collar to protect the area as licking it will make it worse. Wash it with an antibacterial soap and apply a topical antibiotic. I hope this helps!

Your dog may have infected or impacted anal glands. This certainly would explain the discomfort and foul smell. I recommend getting him seen by your vet as soon as possible to have them checked to make sure that is indeed what is going on, expressed and maybe put on antibiotics to help him heal faster.

It could be an [anal gland abscess](https://www.petcoach.co/article/anal-glands-sacs-impactions-infections-abscesses-in-dogs). This occurs when the anal glands do not fully empty during the act of defecation resulting in inflammation, impaction and infection. Have her examined by your veterinarian for confirmation and treatment. This may include sedation followed by lancing, draining and flushing the abscess. Antibiotics and pain management will likely be indicated. Topical treatment may not be sufficient. An e-collar (cone) can be used to prevent licking until she sees the doctor. Afterwards, you can have her glands expressed (emptied) regularly and add additional [fiber](https://www.petcoach.co/article/high-fiber-diets-anal-gland-disease-in-dogs/) to her diet to[ prevent recurrence](https://www.petcoach.co/article/how-to-prevent-impacted-dog-anal-glands).

Thanks for using Petco Pet Education Center, formerly Petcoach! It seems like it may be something causing him discomfort. I recommend that you have Jack evaluated by your veterinarian for further assessment and treatment. A veterinarian would be able to look at the affected area closely and see if there is a wound or anything to explain possible discomfort. Treatment would be based on findings. Good luck!
