Essential Vaccinations for Dogs and Cats: The Complete Owner's Guide

The importance of vaccination.

Vaccination protects companion animals from serious, often fatal diseases, while also contributing to public health. Through the development of immunity, the spread of infectious diseases in the animal population is reduced.

The choice of vaccines is based on the animal's lifestyle, age, geographical area, and risk of exposure to pathogens.

Dog Vaccines

Dog vaccines are divided into core and non-core.

Core vaccines:

*Canine Distemper. *Parvovirus. *Infectious Canine Hepatitis (Adenovirus). *Leptospirosis (considered a core vaccine in many countries due to risk to humans). *Rabies (mandatory in many countries).

Non-core vaccines:

*Infectious Tracheobronchitis (Kennel cough - Bordetella). *Leishmaniasis (in endemic areas).

Indicative schedule:

First vaccination: 6–8 weeks of age. Boosters: every 3–4 weeks until 16 weeks of age. Annual or triennial booster, depending on the vaccine.

Cat Vaccines

Similarly, for cats, there are core and non-core vaccines.

Core vaccines:

*Feline Panleukopenia. *Herpesvirus (FHV-1). *Calicivirus (FCV). *Rabies (where required).

Non-core vaccines:

*Feline Leukemia Virus (FeLV). *Chlamydia.

Indicative schedule:

First vaccination: 6–8 weeks of age. Boosters: every 3–4 weeks until 16 weeks of age. Annual boosters or as per veterinary instructions.

Factors affecting vaccination.

The decision for a vaccination protocol is not the same for all animals. The following are taken into account: *Whether the animal lives indoors or outdoors. *Contact with other animals. *Travel or relocation. *The presence of endemic diseases in the area.

For example, a dog living in an urban environment with limited contact has different needs than a hunting dog.

Safety and side effects.

Modern vaccines are safe, but mild reactions may occur such as: *Slight fever. *Decreased appetite. *Local swelling at the injection site. *Serious allergic reactions are rarely observed, which is why monitoring after vaccination is important.

Conclusion.

Proper vaccination is fundamental to the health of dogs and cats. Collaboration with the veterinarian is essential to tailor an individualized program that will ensure maximum protection.
