Fleas and Ticks: How to Protect Cats and Dogs Year-Round

Fleas and ticks in dogs and cats never really take a break. Warm weather may boost their numbers, but these external parasites can infest your pet all year long, even indoors. Understanding their life cycle and the risks they carry helps you set up effective, ongoing protection instead of just reacting once the scratching starts.

Fleas and ticks: discreet but ever-present parasites

Fleas are small jumping insects that feed on your pet's blood. They reproduce extremely quickly: what looks like a minor infestation at first can soon spread through the animal's coat, then into the carpet, sofa or bedding around the house. Ticks, on the other hand, are arachnids that latch onto the skin, often after a walk through grassy, wooded or bushy areas, and feed on blood for several days if they aren't removed.

These parasites don't just cause itching: they can also transmit diseases that are sometimes serious, which is why regular prevention matters far more than a one-off treatment after the fact.

Warning signs to watch for

• Frequent scratching, excessive licking or nibbling at the coat
• Small black specks (flea dirt) visible when parting the fur
• Redness, scabs or patches of thinning fur
• A visibly swollen tick, often around the head, ears or between the toes
• Unusual tiredness, loss of appetite or a change in behaviour

Health risks from parasite-borne diseases

Beyond the discomfort they cause, fleas and ticks can carry diseases that affect pets, and in some cases conditions that may also concern the humans living alongside them. That's why prevention isn't just about comfort or appearance: it protects the health of the whole household.

An untreated flea infestation can also trigger a skin allergy in some animals, causing intense itching, scratch wounds and localised hair loss. In young or weakened animals, a heavy infestation can also contribute to general debilitation.

External parasite treatments: which options should you choose?

Several types of external parasite treatments are available today, each with its own advantages depending on your pet's lifestyle:

• Spot-on treatments applied to the skin, usually monthly
• Flea and tick collars with long-lasting action
• Oral tablets with systemic effect
• Sprays for quick action, often used as a complement
• Anti-parasite shampoos for one-off coat treatment

The choice of product and how often to apply it should take into account your pet's age, weight, health status (pregnancy, chronic illness) and lifestyle (outdoor access, contact with other animals, young children in the household). A poorly dosed product, or one not suited to the species, can be ineffective or even dangerous: treatments designed for dogs should never be used on cats without professional approval.

Asking a professional for advice remains the best way to choose the protection best suited to your pet. You can browse the directory of vets for dogs or vets for cats to set up a personalised, season-appropriate parasite prevention plan.

Protection tailored to every season

Contrary to popular belief, flea and tick prevention shouldn't stop once winter arrives. Fleas survive very well inside heated homes, and some ticks stay active as soon as temperatures turn mild again.

Spring and summer

• Check your pet more often after each outdoor outing
• Favour open areas during walks, steering clear of tall grass
• Check sensitive spots: ears, armpits, between the paw pads

Autumn and winter

• Keep up regular treatment even if your pet goes outside less
• Wash and vacuum bedding, rugs and fabrics regularly
• Stay alert if your pet lives alongside other animals that spend time outdoors

Prevention over cure: good daily habits

1. Check the coat regularly, especially after a walk in nature
2. Remove a tick as soon as you spot it, without delay, using a proper tick-removal tool
3. Stick closely to the recommended application schedule for your chosen external treatment
4. Treat all pets in the household at the same time to prevent reinfestation
5. Regularly clean your pet's living environment (bed, rugs, car)

Should you still treat a pet that never goes outside?

Yes: fleas can be brought into the house on shoes, clothing or another animal, even if your cat or dog never sets a paw outdoors. Regular prevention is therefore still recommended, at a pace that can be adjusted based on a professional's advice.

Since every animal has specific needs depending on its age, weight and lifestyle, it's always best to have your chosen parasite prevention plan approved by an animal health professional, who can fine-tune the frequency and type of product to your pet's actual situation.
