Core vaccines are essential for all dogs, regardless of their lifestyle—unless a specific medical condition prevents vaccination. According to the 2022 AAHA Canine Vaccination Guidelines, these core vaccines include the Distemper / Adenovirus / Parvovirus / Parainfluenza (DAPP) combination, the Leptospira vaccine, and the Rabies vaccine. These vaccines play a vital role in protecting dogs from serious, potentially life-threatening diseases and are a fundamental part of keeping your pet healthy and safe.

Although vaccinations are vital, adverse reactions can occur, such as facial swelling, skin rashes, vomiting, diarrhea, and, in rare cases, sudden collapse.
