Parasite prevention

Fleas, ticks and seasonal protection

📅 January 20, 2025 ⏱️ 11 min read
At a glance
  • Parasites are prevented before you see them: once you notice fleas, the infestation is already in the house.
  • Fleas, ticks, sand flies and mosquitoes carry different diseases, some of them serious.
  • Protection starts when the vet advises it and follows a seasonal calendar, house cleaning included.

Parasite control in the Staffordshire Bull Terrier is predictable and almost entirely effective, as long as the calendar is kept. The flea you see on the dog is only about 5 per cent of an infestation; the rest lives in the house as eggs, larvae and pupae. The breed's short coat makes fleas and ticks easy to spot, but its skin is prone to allergy, so flea allergy dermatitis is common. Ticks carry babesiosis, ehrlichiosis, anaplasmosis and Lyme disease; sand flies and mosquitoes carry leishmaniasis and heartworm. Puppies are born with roundworm from the dam and are wormed every two weeks from two weeks of age until two weeks after weaning, then monthly until six months. Adults are treated every three months, more often if they scavenge or live with small children, with a faecal examination to check the schedule. A guide by Del Piccolo Diavolo, a Staffy breeder in Ostellato (Ferrara, Italy) since 2013.

Why prevention beats treatment

Parasite control is one of the few areas of dog health where the correct approach is entirely predictable and almost entirely effective. Nearly everything that matters can be prevented with a calendar and a small monthly cost, and nearly every serious case seen by veterinarians involves a dog whose prevention lapsed.

For the Staffordshire Bull Terrier there is one breed-specific consideration worth stating early: the short, dense coat makes fleas and ticks easier to spot than in a long-coated breed, which is an advantage. But the same coat, combined with skin that is prone to allergic reaction, means that flea allergy dermatitis is disproportionately common and disproportionately miserable. A single flea bite can trigger weeks of scratching in a sensitised dog.

Fleas

The flea you see on the dog represents about 5 per cent of the infestation. The remainder (eggs, larvae and pupae) is in the carpet, the bedding, the sofa and the cracks in the floor. This is the single most useful fact about fleas, because it explains why treating the dog alone repeatedly fails, and why an infestation appears to return a fortnight after it was solved.

Signs to look for: scratching concentrated at the base of the tail and along the back, small scabs, and flea dirt, which looks like specks of black grit and turns rust-red on damp white paper. That test is definitive and takes 10 seconds.

Treatment means treating every animal in the household on the same day, plus the environment. Beds, throws and blankets are washed at 60 degrees; vacuum thoroughly, under furniture, along skirting boards and in the cracks where larvae hide, every day while the infestation is active, emptying the bag outside straight away. Carpets and sofas are treated with steam, and heavy infestations need an environmental product with an insect growth regulator (IGR), used as the label says, airing the room well and keeping puppies and people out for the stated time. Repeat after 3 weeks to catch the generation that hatches from pupae, which are resistant to everything.

Ticks

Ticks matter less for the bite than for what they transmit: babesiosis, ehrlichiosis, borreliosis and, in parts of southern Europe, hepatozoonosis. In Italy, babesiosis in particular can be rapidly life-threatening, and it is the reason we treat tick prevention as non-negotiable for dogs that walk anywhere near long grass.

Check the dog after every walk in grass or woodland during the season, which in most of Italy now runs from March to November and in mild coastal areas effectively all year. Run your hands slowly against the coat, feeling for small lumps: ears inside and out, neck, armpits, groin, between the toes and around the anus.

To remove a tick:

  1. Use a tick hook or fine-pointed tweezers, gripping as close to the skin as possible.
  2. Pull slowly and steadily, without jerking and without crushing the tick's body. A hook is designed to be turned gently as it lifts; tweezers are not: pull straight out.
  3. No oil, alcohol or flame on an attached tick: a distressed tick regurgitates, which is precisely how pathogens are transmitted.
  4. Disinfect the spot with chlorhexidine or povidone-iodine and wash your hands well.
  5. The tick can be kept in a small jar of alcohol, if the vet wants to identify it.
  6. Note the date, and watch for fever, lethargy, lameness or dark urine over the following 3 weeks.

Intestinal worms

Roundworms, hookworms, whipworms and tapeworms are the common group. Puppies are effectively born with roundworm from the dam and must be wormed on a strict schedule: every 2 weeks from 2 weeks of age until 2 weeks after weaning, then monthly to 6 months. This is the breeder's responsibility for the first part and the owner's thereafter, and the dates should be written in the health record you receive.

Adults are typically treated every 3 months, adjusted upwards for dogs that hunt, scavenge or live with small children. Tapeworm is transmitted by ingesting fleas, which is one more reason the two problems are managed together rather than separately.

Signs of a burden: a dull coat, a pot-bellied appearance in puppies, weight loss despite good appetite, visible segments like grains of rice around the anus, and scooting, which is more often anal glands but is worth investigating.

Heartworm and leishmaniasis

These are the two that owners in southern Europe cannot afford to treat casually. Heartworm (Dirofilaria immitis), transmitted by mosquitoes, is endemic in the Po Valley and much of northern Italy, including our own area of the Po Delta, as well as around lakes and along the coasts. The adult worms live in the heart and pulmonary arteries, and untreated the disease is fatal.

Prevention is a monthly treatment, tablets or spot-on, through the whole mosquito season, usually from April or May to November or December. In a puppy, prevention starts early, when the vet says so, and the test is done from seven months on. In an adult dog whose history is unknown, the test comes first, because giving a preventive to a dog that is already infected can be dangerous. The test is then repeated every spring, before starting again.

Leishmaniasis, transmitted by sandflies, is endemic across the Mediterranean and expanding northwards. It is a serious, often lifelong disease. Prevention combines a repellent collar or spot-on with proven anti-feeding action, avoiding outdoor exposure at dusk and dawn during the season, and, where recommended by your veterinarian, vaccination. Any dog travelling to or from southern Italy should be protected before the journey rather than after. Documents, car, train and air travel: the practical rules are in the guide to travelling with a Staffy.

A practical annual plan

Monthly: a combined product covering fleas and ticks, chosen with your veterinarian (in winter, decide with them whether to continue), plus heartworm prevention through the mosquito season. Every 3 months: intestinal worming, or more often for at-risk dogs, and in puppies the schedule is checked against a faecal examination. Weekly: a hands-on check of coat and skin, which takes 2 minutes and catches most problems early. Annually: a veterinary check that includes discussion of the local parasite picture, because it changes.

One caution on products: never use a preparation formulated for cats on a dog or the reverse, and never use permethrin-based products in a household with cats. And be sceptical of natural alternatives such as garlic or essential oils. Garlic is toxic to dogs, several essential oils are also toxic, and none of them prevent babesiosis.

The year, season by season

How protection against parasites changes through the year, season by season:

PeriodRiskWhat to do
Spring and summer (March-October)Greatest pressure: the critical period for ticks and fleasRegular treatment, every 4 weeks or as the product specifies; a careful check after every walk in long grass, woods or parks
Autumn (October-December)Adult ticks are particularly activeFull protection, above all in rural, hilly or mild areas: no time to ease off
Winter (December-March)In heated homes fleas stay active all yearDecide with your vet whether to keep full cover; where leishmaniasis or ticks are endemic, twelve months of protection

A reminder on the phone calendar does more than any good intention.

Choosing a product: three formats

The first treatment is chosen by the vet, for the puppy's exact age and current weight.

FormatAdvantagesLimits and how to useMinimum age
Spot-on (pipettes)Practical, work against fleas and ticks for about 4 weeks, suitable for puppiesOn dry skin between the shoulder blades, where the dog cannot lick; no bathing for 48 hoursOften 8 weeks: the age on the product is the one that counts
Chewable tabletsAct quickly throughout the body, not washed off by baths or swimmingSome cover only fleas, others ticks too: check the spectrumPuppy formulations, respecting the minimum weight
CollarsRelease for 6-8 months, broad cover, inexpensive; in the right formulation they repel sandflies tooWorn continuously, with two fingers of slack; can cause local skin reactionsOften 7 weeks: the age on the product is the one that counts

Three rules without exceptions: never use a product for adult dogs on a small puppy; never swap products between dog and cat, because many dog products contain permethrin, which is toxic to cats even through contact with a freshly treated dog; and never combine products without asking the vet.

When to call the vet

Fleas: persistent, intense itching with compulsive scratching, scabs or bald patches, flea dirt in the coat, pale gums in a heavily infested puppy. Tick-borne disease: a temperature above 39.5 °C within three weeks of removing a tick, marked lethargy, loss of appetite, intermittent lameness or swollen joints, small red spots on the gums or belly. A reaction to a product: vomiting or diarrhoea within hours of application, tremors, heavy drooling, unsteadiness, or dermatitis where a spot-on was applied. Red or brown urine, very pale gums, difficulty breathing, collapse or seizures are an emergency: go straight to the nearest emergency clinic.

Frequently asked questions

When should parasite prevention start in a puppy?

Worming starts very early, from two weeks of age, because many puppies are born carrying worms passed on by the mother: it is repeated every two weeks until two weeks after weaning and then monthly until six months. For external parasites, fleas and ticks, treatment usually starts from eight weeks, but the product depends on weight and age, and some active ingredients have precise limits below a certain threshold. The rule is that the vet chooses the first treatment, not the supermarket shelf. A puppy from a breeder who does things properly should arrive with a health record listing the dates of every worming, and ideally the report of a faecal examination: from there you carry on without interruption, because a gap of a few weeks is enough to restart an infestation.

How do I remove a tick correctly?

With fine-pointed tweezers or a tick hook, gripping the tick as close to the skin as possible and pulling with steady, even traction, without jerking; a hook is designed to be turned gently as it lifts, tweezers are not. What must not be done is the whole repertoire of home remedies: oil, alcohol, a flame, petroleum jelly. Suffocating the tick makes it regurgitate into the dog, which is exactly when pathogens can pass. After removal, disinfect the spot and write down the date: most tick-borne diseases have an incubation period of weeks, so if fever, apathy or intermittent lameness appear in the following twenty to thirty days, tell the vet and remind them of the date of the bite.

Which parasite products are best for puppies?

There is no best in absolute terms, only the right one for that puppy, and it depends on age, weight, region and lifestyle. The main families are three: spot-ons, simple and suited to owners who do not need to treat often; chewable tablets, which are not lost with bathing and suit dogs that spend a lot of time outdoors or in water; and collars, which cover long periods. Where leishmaniasis is present, you need products with a repellent action against sandflies, which not all parasite treatments have. Avoid swapping products between cats and dogs, and avoid natural remedies without proven effect, which give the illusion of protection while the dog stays uncovered.

How often should treatments be given?

It depends on the product and the season, and the correct answer is on the leaflet: a spot-on usually covers four weeks, some tablets up to twelve, collars several months. The real mistake is not the choice of product but the winter break: with today's mild winters, ticks and fleas stay active even in January, and in the Po Valley year-round cover is now the norm. Heartworm is different, because prevention is seasonal and has to be in place before the mosquito season starts, after a test in dogs whose history is unknown. Keep a note of treatment dates: nobody notices when a month is skipped, and reinfestations at home are far more tedious to solve than to prevent.

My dog never leaves the garden. Does it still need prevention?

Yes. Mosquitoes carrying heartworm and sandflies carrying leishmaniasis do not need the dog to travel, they come to the garden; ticks can be carried by hedgehogs, birds and other animals that pass through; and flea eggs arrive on shoes, clothing and visiting pets. A garden-only dog therefore needs the same protection as any other, adapted to the area where you live. What changes is not whether to protect but how much to check: a dog that never goes into long grass or woodland needs fewer tick checks than one that does, but not a lower level of prevention. Ask your vet which parasites circulate locally, because the picture changes from one area to the next.
