At least that’s my best guess, based on what my vet said and also a little online research.

Now the question is, will the infection respond to antibiotics, or is there an impaction that will necessitate the surgical removal of the gland?

I’m hoping the former.

Atlas concurs, especially after looking at these photographs of a five pound chihuahua under the knife (not for the squeamish, I warn you).

For now we wait.
