I agree. Lucy was losing a little hair from one side of her nose. Her vet had me put a little antibiotic ointment where her tear stains run (but not right at the eye). He said that sometimes there's a little bacteria in the running tears.

I did it for a couple of weeks and it cleared right up.

I would have a vet look at your dog though because that's quite a lot gone.
