when do newborn puppies get their first shots
A study of a cross section of puppies showed that at 6 weeks, only 25 percent of puppies vaccinated were effectively immunized. At 9 weeks, that increased to 40 percent. At 16 weeks, 60 percent responded to the vaccination, and at 18 weeks, that number increased to 95 percent.
This will depend on the type of vaccine, your pet’s age, medical history, environment and lifestyle. For puppies: If his mother has a healthy immune system, a puppy will most likely receive antibodies in mother’s milk while nursing. Puppies should receive a series of vaccinations starting at six to eight weeks of age.
