I am still learning, but one guess I have would be that you sheltered your pup from developing a natural immunity while young. If I understand correctly, the nosodes should be used (and of course Dr. Falconer mentioned preparation and quality of the nosodes is very important) as a support while the puppy is given intentional controlled natural exposure (in dog parks for example) starting around twelve weeks. The goal here is to allow the puppy to develop a natural lifetime immunity (not from the nosodes, but from controlled regular exposure), so you do not have to be dependent on nosodes. They can be used for support in the future, but hopefully puppy has already developed natural life-time immunity by 9 months. Is this correct, Dr. Falconer?
