Hi. It sounds like Molly is pretty sick and weak. She should be checked out immediately. She could be constipated, have eaten something she shouldn't have, or have a severe kind of infection making her not feel well. With her being unspayed, we worry about pyometra. This is a life threatening infection in the uterus due to hormone changes that causes lethargy, vomiting, weakness, increased water drinking, and even death if not intervened quickly. The treatment is to spay her on an emergency basis. You diagnose it by history, bloodwork, x-rays /- an ultrasound. Get her in right away.

    Any sick un-spayed female dog has a pyometra (uterine infection) until proven otherwise. I would consider this an emergency. Please get her to the vet ASAP for an exam and some testing. Best wishes.
