Hello. It is best not to force anything into a vomiting pet. This could just cause her to vomit more. She will not become seriously dehydrated if you are going to have her examined tomorrow. What you can try is to rub some Karo syrup on her gums, perhaps a teaspoon or two every few hours. This will help to keep her energy levels up, but is she vomits even after you do this, then it is best just to leave her be until your vet can evaluate her tomorrow. Thanks for using Petco Pet Education Center, formerly Petcoach.

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Laila. I always tell clients that if abnormal signs persist, worsen, or other signs develop they need to have their pets assessed right away. If you cannot get her seen right away and the vomiting continues, pull the food and water up just for tonight. Fasting her shouldn't hurt her and it will give her stomach/intestinal tract a slight break. But, if you offer her a little water in the morning and the vomiting returns, you should have her evaluated right away. Just offer a small amount of water in the morning. If she drinks (less than 1/2 cup) and is able to hold the water down for 1 hour, go ahead and give her a small meal of her regular food. Again, if she vomits get her evaluated immediately. Vomiting has many causes including intestinal worms, inflammation, infection, dietary problems (including dietary indiscretion or eating things pets are not supposed to eat, food sensitivities/allergies), ingestion of foreign bodies or exposure to toxins, bacterial overgrowth in the gut, problems in the stomach, intestines, or even problems outside of the intestinal tract/stomach including pancreatitis, kidney/liver problems, metabolic disease (diabetes,etc), endocrine diseases (thyroid or other hormone problems), etc. Usually, in puppies, we worry about intestinal parasites, infection, foreign body ingestion or dietary indiscretion. A thorough history and physical exam with resultant diagnostics such as fecal tests, blood tests, imaging studies such as x-rays/ultrasound can be done to try to determine what is going on. Good luck.
