The 65g dog shampoo bar has been formulated to work with the PH of most dogs skin and fur, however, like most products, results can vary or not be positive with individual animals. 
When using, be sure to thoroughly wet down the pet and then rub the bar over them. It's low bubbly formula is designed to clean but not dry out the coat and skin and easily rinses with little to no residue. A very slight fragrance of lavender is designed to not be so strong it bothers the sensitive noses of dogs, but rather give off a slight pleasant aroma.
