Should young or small pets receive a smaller dose of vaccine?
The entire dose of a vaccine should be given at one time. Vaccines are not developed to give different doses to different size animals, except in some cases, it is recommended that the dose of intranasal vaccines for kittens be reduced. Small breeds of puppies should receive the same dose of vaccine as puppies of larger breeds. All puppies regardless of age, body weight, breed, and gender are given the same vaccine dose.
