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's 2024 PAW Report*, 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.

This is a long form text area designed for your content that you can fill up with as many words as your heart desires. You can write articles, long mission statements, company policies, executive profiles, company awards/distinctions, office locations, shareholder reports, whitepapers, media mentions and other pieces of content that don’t fit into a shorter, more succinct space.

Articles – Good topics for articles include anything related to your company – recent changes to operations, the latest company softball game – or the industry you’re in. General business trends (think national and even international) are great article fodder, too.

Mission statements – You can tell a lot about a company by its mission statement. Don’t have one? Now might be a good time to create one and post it here. A good mission statement tells you what drives a company to do what it does.

Company policies – Are there company policies that are particularly important to your business? Perhaps your unlimited paternity/maternity leave policy has endeared you to employees across the company. This is a good place to talk about that.

Executive profiles – A company is only as strong as its executive leadership. This is a good place to show off who’s occupying the corner offices. Write a nice bio about each executive that includes what they do, how long they’ve been at it, and what got them to where they are.
