Hello and welcome to Petco Pet Education Center, formerly Petcoach. Vomiting can be caused by many different conditions including gastritis (upset stomach from eating something like garbage, raw food, bones, or dead animals in the park, etc.), pancreatitis, obstructions in the gut, as well as kidney/liver/metabolic diseases. Very often amoxicillin will do nothing to help the vomiting, and can make it worse as antiboitics are hard on the guts. I recommend feeding a bland diet of boiled/boneless/skinless chicken breast and boiled rice in small frequent meals (4-6 meals a day of 1/2 cup size meals). If the vomiting continues, or if Mui is lethargic or weak, then I would see a vet right away. If the vomiting stops and she is eating and acting normally then she is likely OK. I would not give any amoxicillin. Best of luck with Mui.
