P.S. Don't Allow any further Vaccinations for your Yorkie.....Period!
Hi Savannah......What your describing is either a Bacterial infection or Yeast Infection.....I think the Yeast smells the worst!
First, you need to find her a new Vet that will take this issue seriously! She is miserable and needs to be treated.....The Vet can actually do a skin scrap of the lesions and send it off to a lab to determine which problem it is.....Antibiotics are used for Bacreria (Usually Staph) and antifungals are used for yeast.....
The medicated shampoo will help if it is for Yeast, also. It will read Malassezia or something like that on the label....A Vinegar Rinse can be used....You want to mix about 30% vinegar to 70% water.....Poor it on after the bath....It will kill the yeast on her skin...
Food plays a vital role in skin problems....What do you feed? If it is a grain heavy diet, you need to change! You want NO wheat, Corn, Soy, By-products, Chemical preservatives, or coloring agents....Read the label on your food....Basically, you want a grain free diet as grains turn to sugar in the system....Yeast feeds off of sugar.....SHe needs a high quality diet that you CANNOT purchase at a discount center or grocery store....Only speciality stores or buy online....
There are many other things to try, but you need to start at another Vet....She needs medication to get this under control!
Adding a good Probiotic to her food daily will help, alot....I don't know which ones are available to you since you are not in the states......A health food store would be the place to find a good one....Your dog would need 1/4 - 1/2 Human dose, daily....
Hope some of this helps.....Good luck.....Karla
