It depends on how bad the scrap was.

depends if it is toxic or not

it still works.

The medicine is not only enough to save your dog from the fleas because the other main factor for getting rid of the dogs flea is to wash him using the good flea removal shampoo and washing should be repeat twice a week. in this way the flea can be removed gradually and your dog will feel fresh and better.

You should give your dog baths with flea shampoo and keep on the treatment of medicine.

If your dogs have fleas first you should take your dog for a bath afterwards you must wash your dog with hot water afterwards you must take your dogs to the vaccination center but in my opinion you must buy a fleas shampoos for dogs the fleas will be removed gradually if this happen again consult the doctors for further treatment it will surely help you

the instructions say at least 5 days. so the dogs/cats natural body oils to build up again so the drops can spread how they are supposed to. also it helps to reduce risk of skin irritatio.
