My new dog is due to have an application of the above in the next few days ( paperwork that came with him said due on 17th - not sure how critical the timing is). This will be my first time in applying it, the vet told me that it leaves a greasy mark where applied which is waterproof. However what I need to know is as Alfie is due for a bath/grooming session should I wait a few days before doing this after the Frontline or should I get the bathing/ grooming done first and then apply Frontline
According to Frontline you can bathe your dog after it has been applied as long as you wait 24 hours after applying. This gives it time to spread and dry after that it stays on even with bathing and shampooing.
Make sure when applying it that you get as much on the skin as you can, even if this means applying it in lots of little spots on the back of the neck. Usually, if you apply it all in one spot too much of it gets on the hair shafts and won't spread properly.
