No, Spot on product should be applied on dry animals, on dry skin and coat. It is recommended that they are applied after 2-3 days from bathing as the skin needs a period to regain its natural balance of oily substances and pH. All the spot on products are carried on the surface of the skin by the skin’s oils.
In cases of frequent water exposure the persistent efficacy may be reduced. In these cases do not retreat more frequently than once weekly. If a dog requires a shampoo bath it should be administered at least 2 weeks after application, to optimise efficacy of the product.
