Question 1

When should I vaccinate my puppy in the US?

Accepted Answer

AAHA guidelines: first DHPP at 6–8 weeks, boosters every 3–4 weeks until 16 weeks old (usually 3–4 visits total). Rabies at 12–16 weeks (legally required in most states). Optional: leptospirosis, Bordetella (for daycare/boarding), Lyme (tick-heavy areas), canine influenza. Boosters at 1 year, then every 3 years for core vaccines; annually for non-core.

Question 2

What do US puppy vaccinations cover?

Accepted Answer

The core US combo vaccine is DHPP — distemper, hepatitis (adenovirus), parvovirus, and parainfluenza. Rabies is a separate legally-required vaccine. Non-core add-ons (leptospirosis, Bordetella, Lyme, canine influenza) depend on your dog's lifestyle and region — your vet will advise.

Question 3

When can my puppy meet other dogs safely?

Accepted Answer

One to two weeks after the final puppy booster (usually around 17–18 weeks). Before then, socialize in controlled settings — carry them in public areas, host playdates with fully-vaccinated friends' dogs at home, and avoid dog parks, sidewalks with unknown dogs, and any contact with stool.

Question 4

How much do puppy vaccinations cost in the US?

Accepted Answer

Plan on $100–$300 for the full DHPP series (3–4 visits), $20–$50 for rabies, and $30–$80 each for non-core add-ons. Annual boosters typically run $50–$150. Low-cost vaccination clinics at shelters and pet-supply stores can be significantly cheaper.

Question 5

Are annual boosters really necessary?

Accepted Answer

AAHA guidance has shifted toward 3-year intervals for core vaccines (DHPP, rabies) after the initial puppy series plus 1-year booster. Non-core vaccines like leptospirosis and Bordetella still need annual boosters. State laws may override AAHA guidance for rabies — check your state.
