I have used this shampoo for YEARS on all my dogs, large and small, and it is probably the best flea shampoo I've ever used. Kills them instantly if use non-diluted and it only take a few minutes if you dilute the solution. Love it, they smell clean and are bug free for at least a week after using this.
