Hello, my name is Dr. Elizabeth and I am concerned about this growth.

Given the history of getting bigger quickly, and the location on Reese's face, I'm worried this is a tooth root abscess:

It could also be another type of infection or something like a cancerous Mast Cell Tumor which can also change very quickly.

It is unlikely to be a big bite or sting because those should get big initially and then shrink over a few hours. Not the other way around.

I recommend to get Reese into the veterinarian tomorrow morning. They'll get a better idea what this is from a physical exam.

Soak her food warm water until it softens. Make her food and water room temperature. Take away any chew toys to avoid any further potential trauma.

I hope this helps and that things get figured out quickly!
