The BO here arranged for the vet to come out today and he's going to scope her. It's a constant trickle but gets worse with exertion. Vet hopes it's an ulcer somewhere in her nose or airway and not GPM.
She's also got a swollen lymph node. Since they have to sedate her they're going to see if her teeth need floated and if so, do it then and there.
So please wish us luck that it's something simple, treatable and not GPM or anything more serious.
