I would have Molly seen by a vet as soon as possible. It sounds like she has a few things going on at the moment that need to be diagnosed and treated medically . The problems using her back legs could be due to arthritis, or problems with her hips, spine, and/or joints. Drinking a lot more and peeing a lot more can be due to diabetes or kidney disease. That would also cause weight loss. The bad breath could be caused by diabetes and dental disease. Finally, peeing her in sleep could be caused by incontinence. She needs a physical exam, geriatric blood panel, and urinalysis to diagnose what is causing all of her symptoms. Once a cause is found, the vet can discuss treatment options with you.
