my 13 year old Labrador has developed a swollen looking muzzle

This answer was rated:

my 13 year old Labrador has developed a swollen looking muzzle and seems to be trying to lick it by tossing her head slightly . she doesn't seem to be in pain . I noticed it this morning ,I cant imagine what might have caused it as a sting or bite doesn't seem likely ,
I just wondered if you might have any other possibilities.
thank you *****
Aloha! You're speaking to Dr. Michael Salkin
You've described angioedema - a hypersensitivity reaction which can arise from an envenomation as you mentioned but also a food intolerance, environmental allergens such as pollens, molds, dust, or dust mites, etc., vaccination, drugs, and even environmental variables such as temperature and humidity. In most cases these reactions will abate within 36 hours unaided but an antihistamine such as chlorphenamine (Piriton) dosed at 4-8mg/dog every 12 hours if necessary can be helpful. In severe cases, an antihistaminic glucocorticoid such as prednisone can be prescribed by her vet.

Please respond with further questions or concerns if you wish.
