An added note, in case the vaccine dosage is worrying you: vaccines are different than medications such as antibiotics that are dosed by (approximate) body weight.

Vaccine doses are quite tiny, since their purpose is only to stimulate the body’s immune response, not to cure a disease. A tiny amount of the vaccine is injected into the body, and (absent an allergic reaction, of course, which is generally not related to the size of the recipient) the body slowly — over the course of several weeks — develops an immune response to it.

The point is that you don’t need to worry that a standard vaccine dose (generally 1 ml) is too much for a tiny toy breed puppy, because it’s not. It’s a tiny dose for all puppies, because the immune response only requires a tiny dose.

You’ll be in the same situation if you go get a vaccination against the flu, or covid, or shingles. Adult humans might range in size from 100 pounds to 400 pounds, but they all get the same dosage of vaccines, because the dosages required are tiny.
