my cocker spaniel has had varying colors of diarrhea over the last 6 days.  Today she started whining and draging her bum on the carpet.  When I went to look at her sphincter, she yelped and tried to bite me, but I could see what looked like a bunch of hemerrhoids protruding about a half of an inch.  right now she's sleeping next to me, but I wasn't sure if I should take her to the vet for hemerrhoids or if I should wait...
