Last weekend I bought Vita Hound because my dog has rash problem or skin problem. The rash would get so bad that she has to take antiboatics. She has been taking Vita for six days and the last four days she has gotten sick. She would vomit yellow fluid. When she gets sick there is no warnings and there is a lot of yellow fluid. I followed the guidelines on website on how much to put the supplement on her food. I don’t know what to do now. Also I have her on science diet food for sensitive skin.
