A sudden swelling under the jaw could be an abscess. Typically these need to be seen by a vet; as they often need to be lanced/drained to get the pus and infection out; then started on antibiotics. Pain medication may be given as well. If he isn't eating, if he's acting lethargic or otherwise not feeling well (vomiting, diarrhea, any change in breathing) seek emergency care. If your vet's office is closed, they likely have a message with who to call or where to seek after hours care in the case of an emergency. If he's still eating and acting ok, you can call and make an appointment at the first possible time. I hope that helps you! Thanks for asking Petco Pet Education Center, formerly Petcoach!
