Dogs need a series of core and non-core vaccines throughout their life to stay healthy and protected from serious diseases. Here’s a clear breakdown of the necessary shots and when dogs typically receive them:
🐶 Core Vaccines (Essential for All Dogs)
These are highly recommended or legally required because they protect against deadly diseases:
| Vaccine | What It Protects Against | Schedule |
|---|---|---|
| Rabies | Fatal virus affecting the brain, required by law in most states | 1st dose at 12–16 weeks, then boosters every 1–3 years |
| DA2PP (also called DHPP) | Distemper, Adenovirus (Hepatitis), Parainfluenza, and Parvovirus | Starting at 6–8 weeks, boosters every 3–4 weeks until 16 weeks, then booster at 1 year, then every 1–3 years |
💉 Non-Core Vaccines (Based on Risk, Region & Lifestyle)
These are optional, but recommended in certain situations:
| Vaccine | What It Protects Against | Who Should Get It |
|---|---|---|
| Bordetella (kennel cough) | Highly contagious upper respiratory infection | Dogs that board, groom, or go to daycare/dog parks |
| Leptospirosis | Bacteria from water, can cause kidney/liver damage | Dogs that go outside, hike, or live in wet/rural areas |
| Lyme disease | Tick-borne illness | Dogs in high-tick areas (NE, Upper Midwest, PNW) |
| Canine Influenza | Dog flu | Dogs in crowded settings or outbreak areas |
| Rattlesnake vaccine | Reduces reaction to bites | For dogs in desert or rattlesnake-prone areas |
🗓️ Puppy Vaccine Schedule (Typical Timeline)
| Age | Vaccine(s) |
|---|---|

| 14–16 weeks | DA2PP (3rd), Rabies, Lepto/Lyme (optional) |
