I always bathe my puppies in warm water and a mild puppy shampoo at just before 8 weeks, drying them thoroughly in a warm place.
The day after their bath I Frontline them as a protection against skin parasites.
Adjust the spray to a fine mist. Dosage is 3 ml per 1kg bodyweight. (Check your frontline dispenser for the amount in ml per pump action). Avoid ears and eyes.
I use Frontline spray every 2 to 3 months, – on adult dogs at a dose of up to 6ml per kg bodyweight. Again avoiding ears and eyes.
This ensures as far as possible that our dogs are free from external parasites.
