We had this conversation some time ago. I was asking the same thing. My boy smelled like a spoiled, sour wash cloth. I tried everything... Then I switched his foods and the smell is gone!!! I don't know exactly what was in the food that caused this, I just know my dog smells way better now!!!coco said:LOL, he is just smelly!!! He is my little shiz tu, so he butt is close to the rest of him. I am going to find some one to drain those bad boys and see if that is what it is. He just smells, kinda sour all the time. Well, may be I can talk my husband in to doing it. Sounds easy, just nasty!!!!!
