From Dog

Faucitis, which is relatively rare in dogs compared with cats, is defined as an inflammatory response within the fauces, the caudal aspect of the mouth.

The fauces (oropharyngeal isthmus), which contains the swallowing muscles is bound by the soft palate, palatoglossal arches and the caudal aspect of the tongue, and includes the palatine tonsils.

Causes of faucitis include:

Clinically affected dogs usually present with a degree of oral pain (pawing at mouth, pain on opening of jaw), trismus and dysphagia.

Treatment depends on cause, but bacterial infections usually respond to broad-spectrum antimicrobial therapy.
