Do you understand that these puppies will not be vaccinated. I use nosodes and recommend that puppies only get one Distemper and Parvo vaccine at 16 weeks old. A naturally raised puppy has a strong and healthy immune system. The reason for waiting till 16 weeks, is because the puppies have immunity from their mother and it doesn't run out till then.
For Rabies, you need to wait till one year old. Look for Thimerosal free rabies vaccine.
detox after vaccines
Tractor supply pet vet clinics offer the Thimerosal free rabies vaccine.
