Pet's info: Dog | Shih Tzu | Female | spayed | 12 lbs
Hi I just found a medium-sized red bump at the tip of my dog's tail. I can tell it is bothering her because she is walking with her tail down and has been pretty sedentary all day. The bump is semi-hard and it hurts her if I touch it. I took a picture of it, but not sure how to show you the picture.

The bump could be caused by an infection, allergic reaction, cyst, benign or cancerous mass. The only way to know for sure is to have your vet do a fine needle aspirate. It is a very easy proceedure that takes just a few minutes. Once it is diagnose, your vet can decide the best treatment. Please call your vet and schedule an appointment, especially since it seems to be bothering her.
