SWOLLEN MOUTH

Question
MY ENGLISH SETTERS MOUTH IS ALL SWOLLEN UP. ANY IDEA WHAT MAY HAVE CAUSED THIS AND WHAT WE SHOULD DO???

Answer
May be an allergic reaction to a spider bite or bug bite.  Best thing to do is to take him to the vet for treatment as the swelling could progress and affect his breathing.  There may be something else going on like a tooth infection but the doctor can determine the problem upon examination and the appropriate course of action.
