I used web-dmv when our puppy came down with strange paralysis. I entered the symptoms and it was spot on. My holistic vet was stumped (and nearly killed her). Fortunately, my vet's partner sent us to a world class neurologist who quickly figured it out and saved her life. (Today she has special needs, but is able to enjoy life and do normal things.) I would use web-dmv again and I believe for a fee you can consult with a real vet (not just the computer).
He prayeth best, who loveth best, all creatures great and small.
