How old have to be the puppy when you can put frontline? My puppies (10 puppies) are 1 month old,and my vet said to me that they can treat with frontline already (because they got fleas ) and I do it yesterday.But today I heard that it is too early and I´m scared now.They are acting normal,everything is the same as 3 days before,they look fine,but I don´t know what consequences might be.Can anyone tell me did I do the terrible mistake?
Fronline???
