My boyfriends mother has a basset hound and he smells really bad. When I first seen his neck, it was all red from him scratching it. Also I noticed that he had a foul odor coming from him. She told me that he has a yeast infection in neck. I mean there are days where you can't even go by him because he smellls so bad. And he has this green/yellowish stuff in his eyes. What can cause all of that? I mean can dogs really get a yeast infection on their necks or any part of their body?
