My pup is 3 months old. She ate a lot since she was with me. I de wormed her last month and there was few worm out. Last few days I de wormed her again half of the tablet she took last month. After 1 one day she feel ill already and vomiting a little water like only a saliva and she never eat anything at all. Seems her stomach is aching. Wanted to vomit but she can't. What will I do to this?
