Most pet parents pack the food, the lead, the favourite toy. Then they board the ferry or pull onto the motorway and realise, somewhere around the first service station, that they forgot the flea treatment. Or the ear cleaner.Or dental care products, Or never actually checked whether their pet's vaccinations were current for the destination country.
This guide is the checklist you will bookmark every summer and actually use. It covers what needs to happen before you leave, what to watch for during the journey, and the section most guides skip entirely: what to do when you get back.

Dogs are routine-dependent but fundamentally adaptable. If their routine travels with them —familiar mealtimes, familiar smells, familiar commands, familiar people — most dogs will settle reasonably well in new environments within 24 to 48 hours. Car travel is generally manageable once dogs are accustomed to it, and a dog who has travelled regularly from puppyhood is usually far less stressed than one whose first long journey happens at age four.
Cats are territory-dependent, not routine-dependent. Their sense of security is tied to the physical environment, not the schedule. Moving a cat out of its territory, even temporarily, is inherently stressful in a way that has no easy equivalent for dogs. A cat who seems calm in the carrier is often in a state of suppressed anxiety, not relaxation.
The practical implication: if you are traveling with a cat, the decision requires more preparation. Cats who need to travel benefit from carrier familiarisation weeks in advance and in some cases veterinary-prescribed anxiolytics for the journey itself. For cats who are genuinely distressed by travel, the welfare calculus of whether the trip is necessary is worth considering honestly.
Requirements vary by destination country, and they change. For travel within the EU and to the UK, the Pet Travel Scheme requires a microchip, a valid rabies vaccination (administered at least 21 days before travel for dogs entering the UK), and an official health certificate or pet passport. Some countries require tapeworm treatment administered by a veterinarian within a specific window before entry.
Check the specific requirements for your destination country with your veterinarian or through the official government portal of your destination at least four to six weeks before travel. Leaving this to the week before departure is the most common source of genuine stress for pet-owning travellers.
This is where preparation most commonly falls short, and the consequences of getting it wrong are real. Travel changes your pet's parasite exposure profile significantly. Different regions of Europe carry different tick species, flea populations vary by climate and altitude, and sandfly-borne diseases like leishmaniasis are endemic across the Mediterranean and are moving steadily northward.
The practical rule is to ensure your pet's parasite protection is active and current before departure, not on the day you leave, which is often too late for products that require time to reach full efficacy. Spot-on treatments, tablets, and collar-based products each have different onset and duration profiles; check the specific timing guidance for your chosen product.
proHibex provides triple-action intestinal support for dogs and is particularly relevant during travel. Changes in environment, water quality, and food routines, combined with the physiological effects of travel stress, often disrupt digestive health. proHibex helps maintain stool consistency by binding and firming loose stools, supports the intestinal flora with both probiotics and inulin (a prebiotic that actively stimulates growth of beneficial gut bacteria), and contributes to the health of intestinal cells. For dogs prone to digestive upset when their routine or environment changes, including it in your pre-travel kit is a simple and effective preventive step.
Travel stress has a measurable effect on the oral environment. Anxiety increases cortisol levels, which can alter salivary composition and pH, creating conditions more favourable to the overgrowth of oral bacteria. Pets with existing gum sensitivity or dental issues may be more prone to flare-ups during periods of stress.
Ideally, dental care should start early as part of a preventive routine, helping to maintain oral health before problems develop. However, it is equally important to recognise that it is never too late to introduce daily oral care — even small, consistent steps can make a meaningful difference over time.
A brief dental assessment before travel — checking gum colour, plaque levels, and any signs of discomfort — is worth doing, preferably a few weeks before departure so there is time to address anything concerning.
Maintaining consistency during travel can be challenging, but there are practical solutions that can help support oral hygiene on the go. Options such as Plaqtiv+ Spray, Orozyme Chews, or Plaqtiv+ Sticks offer convenient ways to continue daily care when regular routines are disrupted.
The risk calculation changes when you cross a regional or national border. A dog who lives in urban northern Europe, given routine monthly flea prevention, is in a very different situation from the same dog spending two weeks in southern Spain, rural Portugal, or coastal Italy.
Ticks are the most significant summer travel risk across Europe. Ixodes ricinus (the sheep tick, which transmits Lyme disease and tick-borne encephalitis) is active from March to October across most temperate regions. Dermacentor reticulatus (the ornate cow tick, which transmits canine babesiosis) is increasingly common in western and central Europe. Rhipicephalus sanguineus (the brown dog tick, the primary vector of Ehrlichia and Rickettsia in dogs) thrives in the warmer Mediterranean climate.
Tick checks after every walk, running fingers slowly through the coat, paying particular attention to ears, between toes, groin, and around the collar are not optional in endemic areas.
Sandflies are small, night-active insects responsible for transmitting Leishmania infantum, a protozoal parasite that causes leishmaniasis, a serious, often chronic disease affecting the skin, joints, kidneys, and immune system. Endemic across Spain, Portugal, southern France, Italy, and the Balkans. Repellent-based collars and topical products with proven repellent efficacy against sandflies are a meaningful preventive measure for dogs traveling to these regions.
Heartworm (Dirofilaria immitis) is transmitted by mosquitoes and has established prevalence across southern Europe, including parts of Italy, Spain, Portugal, Greece, and Turkey. Dogs traveling to these regions without heartworm prevention are at genuine risk, and testing on return is advisable.
The practical rule for travel: consult your veterinarian at least three months before departure to confirm documentation requirements, check transport conditions with your airline or ferry operator, ensure vaccinations and certificates are up to date, and include preventive care in your plan — from parasite control to maintaining daily routines. Bring your pet’s usual food or confirm availability at your destination, pack essential items such as dental care and digestive support, and keep your veterinarian’s contact details easily accessible while you travel.
This is the version that lives in your travel bag, not on your kitchen counter:
Keep the routine as close to home as possible: same feeding times, same walk schedule where logistically feasible, familiar bowls and bedding. Novel environments are stimulating; the routine signals safety.
For car travel, do not feed your pet within two hours of departure : a full stomach significantly increases motion sickness risk. Take regular breaks (every two to three hours for dogs at minimum) for water, movement, and toileting. Never EVER leave pets in a parked car in warm weather, even for a food or toilet-break; interior temperatures reach dangerous levels within minutes.
When You Get Back: The Post-Trip Health Reset (H2)
This section is the one most summer travel guides omit entirely, and it is where problems frequently emerge.
Check for ticks immediately on return thoroughly, including inside the ears, between the toes, in the groin, and under the collar. A tick that has been attached for under 24 hours carries significantly lower disease transmission risk than one found after 48 to 72 hours.
Monitor for delayed stress symptoms. Some pets, cats especially, do not show obvious signs of stress during a trip but decompress afterwards: changes in appetite, altered toileting habits, increased vocalisation, or withdrawal. These typically resolve within a week, but watch for signs that linger.
Reset the oral routine. Travel is the most common reason we see daily dental habits disrupted. The first week back is the moment to re-establish it rather than let the disruption become permanent.
Consider a post-travel check. If your pet has visited higher-risk regions — particularly areas where diseases such as Leishmania or heartworm are endemic — a veterinary review after returning is advisable. Early testing can detect exposure before signs appear, allowing timely management.
Does my dog need parasite protection before a trip?
Yes and ideally not on the day of departure. Many products take 24 to 48 hours to reach full efficacy. Apply at least 48 hours before travel, and ensure the treatment covers ticks if you are heading to rural or coastal areas. Check the specific product's coverage claims — not all flea treatments are also effective against ticks.
How do I calm a cat in the car?
The best intervention is prior habituation. Leave the carrier out at home as furniture for several weeks before travel; feed the cat in it, place bedding in it, let it become a neutral space rather than a threat. For genuinely distressed cats, speak to your vet about safe anxiolytic options before the journey.
Can travel cause dental problems in pets?
Travel stress can trigger or worsen oral inflammation in pets with existing dental disease. Maintaining the daily dental routine during travel — a chewing strip after the evening meal, or a brief gel application — is a two-minute intervention that prevents the weeks of backsliding that often follow a holiday break in routine.
What parasites should I protect against in summer in Europe?
For most of Europe: fleas and ticks at minimum. For southern Europe (Spain, Portugal, Italy, southern France, Greece, Balkans): also sandflies and mosquitoes. Specific product recommendations will depend on your destination, your pet's existing prevention programme, and their health history: your vet is the right person to advise on the combination that covers your travel profile.
My pet seemed fine on the trip but is acting strange since we got back, is that normal?
Behavioural changes in the first week after return are common, particularly in cats, and often reflect decompression from travel stress rather than physical illness. Monitor appetite and toileting carefully. If changes persist beyond a week, or if your pet is not eating, consult your vet.
Do I need a pet passport for travel within the EU?
For EU-to-EU travel, a pet passport is the standard document. For travel between the EU and the UK, the requirements changed after Brexit : your pet will need an Animal Health Certificate (AHC) issued by an Official Veterinarian within ten days of travel, alongside microchip and rabies vaccination documentation. Check the current requirements for your specific destination before every trip, as these can change.
