Hi, I have a cavalier King Charles and he has been vomiting profusely for almost 24 hours, will not eat or drink, has diarrhea, and has no energy. He is never like this. What should I do or what do you think this might is?

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting, inappetence and diarrhea can be observed with conditions such as gastroenteritis, pancreatitis, dietary indiscretion, gastrointestinal foreign body ingestion and obstruction, among other possibilities. For this reason, I highly recommend that you have Finlay evaluated by a veterinarian for further assessment and treatment as soon as possible as I am afraid he is likely becoming dehydrated. They would be able to check for these possibilities and also check his hydration status and give him medications to make him feel better. Good luck!
