Good morning, I woke up this morning and discovered my 13 year-old Yorkie had lots of watery diarrhea. She was laying down and her hind legs were very weak. She is refusing to drink water.

I am sorry to hear that Dazzle isn't feeling well. There are a few possibilities for diarrhea with weakness, intestinal parasites, dietary indiscretion, bacterial or viral infection, stress colitis, autoimmune disease, systemic disease (liver, kidney, pancreas, diabetes), pain, among others. Pain and weakness in the hind can be caused by disc issues in the back. If she refuses food or water, she may also be experiencing nausea. Continue to offer her fluids (water or pedialyte) and some bland food (boiled chicken breast, cooked white rice, cooked egg). If she doesn't start to perk up in a few hours, I would recommend that she be evaluated by an emergency veterinarian. After a thorough physical exam, the vet may recommend bloodwork, x-rays, or abdominal ultrasound to try to get to the root of her illness.
