My puppy, a 5 mo. old rat terrier/shitzu mix has been constantly scratching but no sign of fleas. I came across Nzymes.com which discussed rabies shots which change the Ph in the body and pave the way for yeast infection. They discuss diet, No corn, corn gluten, brewers rice and other items which add sugar to the system and increase the problems. So far, I can't afford to help him but have started him on plain yoghurt which has helped. But he still smells horrible. Check this site out to see if it will help.
