My dog has a yellow, popcorn-sized lump on her face. What is it?

Pet's info: Dog | Mixed Breed | Female | unspayed | 4 years and 10 months old

Hi, i was petting our dogs face and felt something odd. I moved her hair around to see the source, and saw a medium sized ball seemingly attached to the right side of her face possibly on the skin. It looks to be yellow in tone and resembles a popcorn kernel in color and size except it’s a tad bigger. We’re curious what it could possibly be, and i’ve researched and found some information before she goes to the vet. We just wanted an idea. She hasn’t shown any other symptoms or acted odd.

This could be a cyst, an abscess, a benign tumor, or a malignant tumor. 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. Having Rosie seen by a vet for this a good idea. I hope this helps!
