Swelling on One Side of a Chihuahua's Face That Drains Pus
by Jom
A swelling on one side of the face that drains pus is often an abscess, and in small dogs a common cause is an infected tooth root in the upper jaw. Bite wounds and foreign bodies are other possibilities.
Please see a vet. Antibiotics alone often don't cure a tooth root abscess, so your vet may recommend dental X-rays and treating or removing the tooth.
See dog eye infections for eye-area swelling.
