Core vaccines are considered essential for all dogs due to the widespread and severe nature of the diseases they protect against. The core vaccines for dogs include:
1. Canine Distemper Virus (CDV): This highly contagious and potentially fatal virus affects the respiratory, gastrointestinal, and nervous systems of dogs.
2. Canine Parvovirus (CPV): CPV is a highly contagious virus that attacks the gastrointestinal tract and can be deadly, especially in puppies.
3. Canine Adenovirus (CAV-2): This virus causes infectious hepatitis and respiratory infections in dogs.
4. Rabies: Rabies is a fatal virus that can be transmitted to humans. It is required by law in most places.
These vaccines are crucial in preventing serious and often fatal diseases in dogs. Consult with your veterinarian to ensure your dog is up to date on their core vaccinations.
