Fleas and ticks

Fleas and ticks have been shown to spread a number of diseases, some of which can be a serious health risk to humans such as Lyme Disease and Bartonellosis.

Successful tick and flea protection not only removes the irritation for your dog but it is also essential to stop the spread of disease. 

Find out more about the parasites that your dog might be carrying and how to protect your four legged friend and your family from some of these unwanted pests!

Why protect against fleas?

Ever see your dog scratching and it makes you itch too? Fleas are notoriously difficult to get rid of; once you have them, and they can easily be picked up by dogs all year round, so it is important to make sure that your best friend is protected.

Not only do they cause your dog to itch and scratch but they can also carry nasty diseases and infest your home!

Why protect against ticks?

With 1 in 3 dogs1 found to be carrying them, ticks are probably more common than you think. Not only are they unpleasant but they are known to carry harmful pathogens which are potentially fatal.

These diseases can be transmitted to your pet quickly and ticks can be difficult to locate on your dog as they deliberately find places where they are less likely to be disturbed or found.

Therefore it is recommended to protect against ticks rather than wait to remove them.

Big Flea and Tick Projects


We have worked to research the most common parasite threats to the nation’s dogs and cats: fleas and ticks. Working closely with vets and practices up and down the country, we have created The Big Tick Project and The Big Flea Project – the biggest initiatives of their kind.

Working with the University of Bristol to study the parasites, these projects are leading the way in evidence-based understanding of ticks and fleas in the UK and are raising awareness of their prevalence and of the diseases they may carry.
