Dogs do not need every available vaccine, but they do require a core set of vaccinations (Rabies, Distemper, Parvovirus, and Adenovirus) to protect against fatal diseases. Non-core vaccines (such as for Lyme disease, Bordetella, or Leptospirosis) are based on lifestyle and risk.

What vaccines do dogs absolutely need?

Absolutely necessary dog vaccines (core vaccines) protect against deadly, common diseases and include Rabies, Canine Distemper (D), Adenovirus (Hepatitis - H), Parainfluenza (P), and Parvovirus (P), often combined as DHPP or DAPP, plus Leptospirosis, depending on location/risk. These are essential for all dogs due to the severity and prevalence of these illnesses, with Rabies often legally required.
