With the degree of vomiting you report over the past few days, I am concerned.There are many causes for vomiting in a dog - infectious causes, an upset stomach (gastroenteritis) metabolic causes (kidney, liver, etc.), BUT - there can also be causes of vomiting such as pancreatitis and even a bowel blockage which is life threatening.What can we try now?You can try to offer small amounts of water or diluted pedialyte for hydration and electrolytes. You can even purchase a dropper from your local pharmacy to offer the water/pedialyte mixture by mouth.But I do think that seeing a veterinarian and testing such as belly x-rays is a very good idea here to make sure there is not a more serious cause such as a blockage.I hope this information is helpful!_____________________________________________Please click "ACCEPT" if the information I have provided has been of help so I receive credit for my work.
