How long a mange product takes to work depends on the dog itself. If the dog has an immune issue the mange mites can take a very long time to get rid of and may also require an oral medication. If the dog is very healthy and the case of mange is light it can take 4-8 weeks to get rid of the mange. We do recommend that you seek the advice of a veterinarian to determine what type of mange (either scarcoptic or demodex) your puppy has and what treatments he/she recommends.
