Hi! My name isXXXXX and I am a licensed veterinarian. I am here to help answer your questions but please remember that advice and diagnosis over the internet can never replace advice given in person after a thorough physical examination and evaluation of lab work.Please be patient as some responses can take some time to type out. In addition, please do not forget to rate our interaction after I have answered all of your questions.
I would like to find out a little more information from you regarding Mickey Curley if you don't mind. Has there been a diet change recently? More people food? Getting into the garbage? These things can cause general GI upset, but normally the vomiting with such will resolve in 24 hours.
Given Mickey Curley's age and symptoms, I think it is a good idea to have him checked out by a veterinarian. There are many things that can cause vomiting and excessive drinking such as diabetes, kidney disease, etc. Even if Mickey Curley has been healthy his whole life, these are things that can begin to show signs acutely.
His veterinarian can run some general bloodwork to check for metabolic disorders at his appointment. Even if the bloodwork is normal, it will serve as a good baseline as Mickey Curley ages further and will rule out some serious diseases. In the meantime, you can try to feed Mickey Curley a bland, easy to digest diet, such as boiled skinless chicken breast with white rice. In addition, you can give a human medication called Famotidine (brand name is Pepcid) at a dose of 0.22 - 0.5 mg/pound body weight every 12 hours. (If Mickey Curley weighs 25 pounds his highest dose would be 0.5 mg X 25 pounds = 12.5 mg famotidine....you could round this dose down to 10 mg). Please feel free to reply with any additional questions and I will get back with you as soon as possible. It would be my pleasure to help you with Mickey Curley!
