How Often Should I Vaccinate My Pet and Why?

While we understand the importance of immunizations for ourselves, it’s equally crucial to consider them for our furry friends. Pet vaccinations, whether for our canine or feline companions, play an integral role in protecting them from life-threatening diseases. In today’s conversation, let’s delve into the extensive world of pet vaccinations.

Understand Pet Vaccinations

Vaccinating our pets may seem daunting, especially when you’re a new pet parent. However, understanding the importance and necessity of these shots makes the entire process more manageable. Pet vaccinations are preventive measures administered to keep our pets healthy and extend their lifespan. As medical breakthroughs in the pet healthcare realm continue, we now have access to treatments that can control deadly diseases. Viruses like parvovirus in dogs or often lethal panleukopenia in cats can now be prevented through regular vaccinations.

The Necessity of Vaccination

As pet parents, we often wonder, ‘Why do we need to vaccinate our pets?’ Is it because veterinarians say so, or is there more to it? Vaccinations help prime your pet’s immune system to build resistance against specific microbes. Consider them your pet’s shield against disease-ridden arrows shot by harmful pathogens. Immunization sends a false alarm to their body, simulating an attack from these pathogens. The immune system develops antibodies to fight these fake invaders, ensuring they’re ready for the real deal when it happens.

Standard Pet Vaccination Schedule

Much like human babies, puppies, and kittens have their vaccination schedule. Starting from as early as six weeks, initial doses are administered, followed by booster shots at different stages of their life. Tracking these injections in their vaccination record is essential, ensuring that your pet gets their shots on time. Veterinarians usually provide this record and guide you through the process.

Core Vs. Non-Core Vaccinations

Core Vaccinations

These are the essential vaccines recommended for every pet, regardless of their lifestyle or location. They protect against diseases that are widespread, highly contagious, and typically severe or fatal. Below is a list of core vaccines for dogs and cats:


  • Canine Parvovirus: This highly contagious virus affects dogs of all ages but is particularly severe in puppies. It can cause severe diarrhea, and vomiting, and can be fatal. 
  • Canine Distemper: This highly infectious disease affects a dog’s respiratory, gastrointestinal, respiratory, and central nervous systems, as well as the conjunctival membranes of the eye. 
  • Canine Hepatitis (Adenovirus): This can lead to severe liver or kidney damage, and in many cases, is fatal. 
  • Rabies: This fatal disease can be transmitted to humans and other pets, making vaccination crucial.


  • Feline Panleukopenia: Also known as feline parvovirus or feline distemper, this is a highly contagious and often fatal disease in cats. 
  • Feline Herpesvirus: This disease primarily affects a cat’s respiratory system and can lead to severe upper respiratory infections. 
  • Feline Calicivirus: It causes respiratory disease and oral disease in cats. 
  • Rabies: Even indoor cats should be vaccinated against this disease, as it can be fatal and is transmittable to humans.

Non-Core Vaccinations

These are optional vaccines that should be considered based on a pet’s specific needs, which can be determined by factors such as breed, age, health status, and lifestyle.


  • Kennel Cough: This vaccination is recommended for dogs that frequently visit boarding facilities, dog parks, or grooming salons. 
  • Lyme disease: This is recommended for dogs that live in or travel to areas where ticks are prevalent. 
  • Leptospirosis: This disease can be contracted from the urine of infected animals and can be transmitted to humans.


  • Feline Leukemia: Recommended for cats that spend time outdoors or live with other cats that might be infected. 
  • Feline Immunodeficiency Virus: This is recommended for cats that may be exposed to the virus, which is often through deep bite wounds during aggressive fights. 
  • Bordetella: Generally recommended for cats that are boarded frequently or residing in a multi-cat household. Your vet can guide you on which non-core vaccinations suit your pet’s needs. 

It’s crucial to keep a dialogue open with your vet and discuss any lifestyle changes, as these may impact the vaccines your pet requires.

Repercussions of Neglected Vaccinations

Overlooking vaccinations exposes your pets to various diseases. For instance, if left unvaccinated, a pet could contract distemper, a viral illness with severe implications. Rabies, a peculiar concern in unvaccinated pets, is lethal and can also be transmitted to humans.

Risks Vs. Benefits of Vaccines

Vaccinating pets, like any medical procedure, comes with potential risks and decipherable benefits. On the one hand, they significantly mitigate the risk of disease contraction; on the other, there’s a slight chance of adverse reactions. Pets might experience mild fever, sluggishness, or reduced appetite post-vaccination, which usually resolves within a day or two. Severe reactions like swelling of the face or breathing difficulty are rare but warrant immediate veterinary attention.

Vet Parasite Protection and Vaccination

In addition to regular vaccinations, pets also need protection against parasites. This responsibility falls under the purview of overall pet healthcare and can often be addressed during vaccination visits.

Vet Laboratory

Lab tests and screenings are part of a complete veterinary examination, often coupled with vaccinations. These tests help identify health issues that might otherwise remain undetected. For more information about complete pet healthcare, click here.

Vet Internal Medicine

Vaccines and preventatives are part of a wider medical field catering to pets – Veterinary Internal Medicine. This also covers preventive care, diagnostics, and treatments for numerous ailments. It includes managing diseases of the gastrointestinal system, liver, pancreas, and even endocrine disorders. Clinics such as the Bruceville pet clinic provide a comprehensive range of these services.


Navigating through your pet’s healthcare journey might seem overwhelming, but remember, their wellness is dependent on regular vaccinations and overall healthcare. We’re essentially granting them more healthy years to share with us by safeguarding them from disease through vaccination. The real question is not ‘How often should I vaccinate my pet?’ but rather, ‘How can I ensure my pet gets the care it deserves?’
