My 8 year old border collie just got over a tape worm infection two weeks ago and now she has been vomiting about once a day for three days and her stool is very runny. What should I do?

Withhold food for 24 hours, allowing small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with one tablespoon of food every hour and gradually increase the amount if there is no vomiting. Feed bland until the vomiting has stopped and the stool is normal then transition slowly to her regular diet. If the vomiting or diarrhea persist or if she develops lethargy, loss of appetite or abdominal pain, have her rechecked by your veterinarian. Tapeworms are spread by fleas, so you will need to treat her and the environment for fleas and repeat the deworming in 2 weeks.
