Is There A Good Shampoo For A Stinky, Itchy Dog?

From the symptoms you described, Happyflowerlady, it sounds like she may have a yeast infection. I have noticed that she frequently licks or chews at her paws or toes. I see the dog all the time because she mainly stays on my front porch during the day while my brother is at work. (My brother's house and mine are close together). The smell is also horrific. It's not a regular dog smell, it's something else that's hard for me to describe and sometimes the smell is worse than at other times. Maybe this depends on what she has eaten. I'll tell my mom about the vinegar and hydrogen peroxide, and hopefully that will help her. Thanks for the information and link to the video.
