ok so heres how I do my vinegar rinse, I use either plain filtered ACV or the white vinegar, either one is fine for the rinse. ( I use the ACV with the mother in their food , just about a cap full or tsp in a meal, because I found we were wasting it in the water).
for the rinse, in a gallon jug I put 1 cup of white vinegar to 1 gallon water. Shampoo , rinse, and then pour vinegar mix over pooch. leave on do not rinse off. dry and enjoy the smell while your best friend is enjoying their new skin feeling. It makes a huge difference , you won't believe the clean feeling
