Thank you for that advise. I have 3 rottweilers that stay indoors.Replied by Suseeq (Sydney, Australia) on 05/26/2016
Should start killing fleas straight away. Apply once a day day for seven days then back off - once or twice a week. Then only when you see evidence that they have come back. I personally can't remember when I had to retop my dogs.
