Will Bio Spot® Spot On® Flea & Tick Control for Dogs still work after my dog gets shampooed or wet in the rain?
Yes. If your dog sometimes gets wet in the rain or you bathe him with a mild shampoo, Bio Spot® Spot On® Flea & Tick Control for Dogs should still work. However, if your dog gets wet often or is bathed with a detergent soap, some of Bio Spot® Spot On® Flea & Tick Control for Dogs’ active ingredients may be washed away, thus reducing efficacy. Bio Guard® Shampoo from Farnam has been developed to wash up your pet without washing out his flea control protection.
