The 81 Percent: Rethinking Parasite Prevention

Every month, millions of dog guardians use flea and tick treatments - not out of carelessness, but out of care.

Because they want to protect their dogs.
Because that’s what they’ve been told.

But what if that story is incomplete?

Why “The 81 Percent”?

According to the PDSA, 81% of UK dog guardians use these treatments routinely — without signs of infestation.

That’s a lot of chemicals being used “just in case.”

Treatments, Not True Preventatives

Most products don’t stop bites.

They work after the bite — using pesticides that circulate in your dog’s system.

If it kills a parasite, what else might it affect?

The Bigger Picture

These chemicals don’t stay on your dog.

They move into homes, waterways, and ecosystems — contributing to wider environmental impact.

Why This Campaign Exists

This isn’t about blame.

It’s about more informed, individualised decisions.

Because not every dog has the same risk —
and care shouldn’t be one-size-fits-all.
