Phenergan can be used in dogs under the direction of a vet for allergic causes or for sedation for hypersensitivity disorders. It is not used to treat diarrhea in dogs, so no I would not give it to Cleo. You can try a home remedy before needing to take her into a vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
