Yes, Dawn will kill the fleas that exist on the dog, but so will any shampoo. It doesn’t have to be marketed to kill fleas. They will die from ingesting it. However, Red is right, Dawn does not actually do anything to repel them and over time using Dawn too much, will cause your dogs skin to dry out. This is knowledge I got while working as a bather at a grooming salon.
