This depends on the flea preventative you intend to use. You can use Frontline Spray in very young puppies as well as the mother. Spot-ons are very concentrated and should not be used in puppies younger than three months old and these puppies need to have an appropriate weight depending on the medication. There are puppy spot ons available. Your vet should have all these available.
