> I can't say 100% but I'm pretty sure that mumps isn't communicable between man and dog.
It's very rare.... but happens
Published research paper stated cases (not sure if link will show more than abstract as I'm a member)
Known as parotiditis (sp??) swelling/infection of the Parotid gland.
I should'nt worry until you've seen your Vet and know what your dealing with as it could be any number of things as already said from stings to infection.
As it's near her airway your best bet is to keep an eye on her if the swelling is still ongoing.
Best wishes for the Vet visit x :)
(lovely to see the Macedonian flag! BTW)
