WHAT YOU NEED TO KNOW ABOUT FLEAS, TICKS AND THE OTHER PARASITES THAT CAN HARM YOUR PET WHEN YOU TRAVEL

The trouble with travel 

If a pet travels to an area with parasites that aren’t found in their home country, they risk picking up ‘exotic’ diseases that they aren’t prepared for and could bring parasites back with them on their return journey.  

For example, researchers in Germany found that 12.2% of dogs imported from the Mediterranean countries or that had travelled there with their owners were positive for leishmaniosis, a dangerous disease transmitted by sandflies and which is not supposed to exist in Germany¹. 

In the UK, the Tick Surveillance Scheme analysed ticks from animals returning from a trip abroad, mainly dogs (92.3%). 44.1% were Brown Dog Ticks, which can transmit a host of diseases to our four-legged friends, including babesiosis². 

As vector expert Laura Kramer:

“OWNERS TRAVELING WITH THEIR DOGS WITH THEIR CATS GO TO AREAS ENDEMIC TO CERTAIN DISEASES THAT MAY NOT BE PRESENT AT HOME”

A whole host of parasites can target your pet and spread diseases like babesiosis and heartworm. Find out why they’re spreading, and what you can do to keep your dog or cat parasite free.

Many illnesses are spread directly from one person to another, like colds and flu. But others need a means of transport to get to their intended victim, whether that’s you, me, or our pets. This is the case for parasitic diseases.

There are hundreds of different parasites, but some of the most common ones include:

These species vary considerably in their basic structure: for example, mosquitos are insects, while ticks are arachnids (the same class as the spider). Their ‘mode of attack’ varies too: mosquitos and sandflies fly to reach their target, while fleas jump and ticks latch onto host animals as they brush past.

What they all have in common, however, is that they serve as vectors for disease. In other words, they transmit infections when they bite their host animal.

Why nice weather means fleas on cats and dogs for longer

Changing weather and seasonal shifts are affecting where parasites can be found, and at what time of the year.

Parasites are often tiny and capable of travelling only short distances. But they can travel hundreds of miles in the coats of animals or in human shipments.

Until recently, these species faced a natural barrier: the warm, humid climates they need to thrive could only be found in certain parts of Europe, and at specific times of year.

However now temperatures are rising across Europe. This means the so-called ‘parasite season’ has extended all year-round and many species are able to thrive in areas which would previously have been too cold.

What this means for our pets

For cats and dogs, there are several specific consequences to bear in mind:

• Year-round threat. In most areas there is no longer a ‘parasite season’: common threats to companion animals, like fleas in cats or dogs, are now being discovered all year-round.
• Geographic spread. Many parasites that were previously limited to southern Europe, and even further afield, are now being discovered in northerly countries like Holland, Germany and the UK.
• Introduction of exotic species. A parasite that was once considered exotic, like the Tiger mosquito, can now be found in the northern parts of Europe.

This means that parasites have more time to spread diseases, and each European country is having to deal with new species bringing diseases which haven’t been seen there before.

Many pet diseases, such as leishmaniosis, which can cause organ failure in our pets, are now endemic in certain parts of Europe. Others, such as babesiosis, are spreading fast.

Keep your pets safe – wherever they are

If you are travelling with your pet, speak to your vet to make sure your pet is protected against parasites and diseases in your destination. Our free newsletter can help keep you up to date with the spread of parasites and provide you with best-practice scientific information so you can keep your pet out of reach of parasites – whether they’re at home or abroad.
