Vaccines for pets: should you or shouldn’t you?

There are real risks, and you should be cautious.

Here is something that I think you should be giving to your dog or cat regularly, as it can help support their immune system fight disease- without many of those potential nasty side effects.

The Hidden Risks of Over-Vaccination in Dogs and Cats

As a former holistic veterinarian, I’ve seen firsthand how over-vaccination can lead to chronic health issues in our pets, from allergies and immune disorders in our dogs, to Kidney disease and Urinary Tract disease in our cats. While vaccines have an important role in protecting our furry family members from serious diseases, there’s growing evidence that less can sometimes be more. Here’s what every pet parent needs to know:

1. Too Many, Too Often

Did you know your dog could be getting 6–7 vaccines per year if they’re receiving “non-core” vaccines along with routine boosters? This practice not only stresses their immune system but also increases the risk of vaccine-related side effects.

2. Are All Vaccines Effective?

Not all vaccines provide strong or lasting protection. For example:

• Lyme Disease Vaccine (dogs): Its effectiveness is questionable, especially in areas with low Lyme disease risk.
• FIV/FeLV Vaccines (cats): Often given annually, yet the risk of side effects can outweigh the benefits in low-risk cats.

3. Long-Lasting Immunity Is Real

Studies show that many core vaccines last far longer than previously thought. For example:

• The Canine Parvovirus Vaccine has been shown to protect dogs for up to 7 years – yet it’s often still administered every 3 years. It may even confer lifelong immunity in many dogs.

So, why overdo it when your pet’s immunity is already strong?

4. One Size Does NOT Fit All

Here’s something to think about:

• A 150 lb. Great Dane and a 5 lb. Chihuahua receive the same vaccine dose.
• Smaller dogs often experience more severe side effects – likely due to their size in proportion to the vaccine volume.

Isn’t it time we considered a more tailored approach?

5. Real Risks of Vaccine Side Effects

Vaccine reactions are rare but real. Some examples include:

• Allergies and Immune Diseases in Dogs: Chronic skin issues and autoimmune diseases are sometimes linked to over-vaccination.
• Injection-Site Sarcomas in Cats: A small percentage of cats develop cancer at vaccine injection sites.

What’s the Solution?

I recommend a minimal vaccination approach focused on these principles:

• Administer only core vaccines (like rabies and parvovirus) when necessary.
• Space out vaccines to reduce stress on your pet’s immune system.
• Discuss titer testing with your vet to measure your pet’s immunity levels before giving boosters.

Your pet’s health isn’t about checking boxes – it’s about what’s best for them.
