Border Terrier

Temperament & personality

Borders are cheerful, affectionate and remarkably level-headed for a terrier. They bond hard with their people and genuinely want to be part of family life, not shut out in a kennel. Most are good-natured with children and tolerant of the noise and chaos that comes with them, though as with any dog you supervise toddlers and teach both sides some manners.

They are game and courageous, a trait bred in for a reason, so a Border will happily chase anything small and fast. Squirrels, rabbits, next door's cat and the occasional low-flying pigeon are all fair targets. Recall can be reliable with work, but many owners keep a long line in place near roads and livestock because a hunting terrier in full flight has selective hearing.

Sociable with other dogs in general, Borders usually settle well into multi-dog homes and often do fine at daycare or the park. They are not natural guard dogs. A Border may bark to announce a visitor, then invite them in for a fuss. Left bored and under-exercised, though, a Border will dig, chew and find its own entertainment, so give the brain a job as well as the legs.

Vaccination schedule

Border Terrier puppies follow the standard UK core vaccine plan. The DHPP combination covers distemper, hepatitis (adenovirus), parvovirus and parainfluenza, and is usually given as a first dose around 6 to 8 weeks, then a second dose 2 to 4 weeks later. Most UK vets complete the primary course between 10 and 12 weeks of age, and your puppy is not fully protected until roughly a week or two after that final injection.

Rabies vaccination is not legally required for dogs living in the UK, but it is mandatory for pet travel under the Animal Health Certificate scheme. If you plan to take your Border abroad, book the rabies vaccine well ahead, as it must be given at least 21 days before travel.

Leptospirosis is now a core vaccine recommended for every dog because the bacteria live in water and soil; an outdoorsy, water-happy terrier faces even higher exposure, which is one reason the annual booster matters. Kennel cough (Bordetella) vaccination is worth discussing if your dog uses boarding kennels, daycare or group training. After the puppy course, your vet will set a tailored booster plan. Under current guidance, core components are typically given every three years while lepto is boosted annually, but your vet decides the right interval for your dog.

Best food & diet

Feed a complete, good-quality diet formulated for the right life stage, puppy food while they are growing, then an adult small-breed formula. Borders are active little dogs with a good appetite, so protein and fat levels that match their working-terrier metabolism suit them well. Split the daily ration into two meals to keep energy steady.

Weight is the single most important thing to watch. Borders have a reputation for being greedy and will happily convince you they are starving, but excess weight strains their joints and their heart. Feed by body condition rather than by the label alone. You should feel the ribs easily under a light covering and see a waist from above. Keep training treats small and subtract them from the daily total.

There is nothing exotic needed here. Fresh water always available, sensible portions, and a consistent routine. If you feed a raw or home-prepared diet, get it balanced by a canine nutritionist so it is not short on calcium, minerals or key vitamins.

Common health problems

Borders are one of the more sturdy small breeds, but a handful of conditions turn up often enough to know about. The most breed-specific is canine epileptoid cramping syndrome, widely known as Spike's disease, a paroxysmal movement disorder. Affected dogs have episodes of muscle cramping, trembling, difficulty walking and an arched back, while staying fully conscious throughout. It is often mistaken for a seizure but is a different mechanism. Many affected dogs improve on a gluten-free diet, so ask your vet about trying an elimination diet.

True idiopathic epilepsy also occurs in the breed and causes genuine seizures with loss of awareness. If your Border ever has a collapse or convulsion, film it on your phone if you safely can, because that footage helps your vet tell a seizure apart from a cramping episode and pick the right treatment.

On the orthopaedic side, hip dysplasia turns up in the breed, and like many small dogs a Border can develop patellar luxation (slipping kneecaps), both of which cause lameness or an odd, skipping gait. Your vet may also hear a heart murmur at a routine check; most are harmless flow murmurs, though a few need follow-up. A yearly exam catches most of these early, when they are easiest to manage.

Allergies & skin

The Border's dense, wiry double coat is fairly weatherproof and less prone to problems than many breeds, but skin issues still crop up. Environmental allergies (atopic dermatitis) to pollen, house dust mites or grasses show up as itching, licking paws, rubbing the face and recurrent ear infections, usually starting in the first few years of life.

Food sensitivity deserves special mention in this breed because of its overlap with Spike's disease. Some Borders do noticeably better on a gluten-free or novel-protein diet, and a properly run elimination diet under veterinary guidance is the honest way to test that rather than guessing with over-the-counter foods.

Flea allergy dermatitis is the other common trigger, where a single bite sets off intense itching, so year-round flea control matters even for a mostly indoor dog. Keep the coat hand-stripped rather than clipped where possible, since stripping preserves the harsh protective texture that helps shed dirt and water. If you spot persistent scratching, hair loss or sore skin, get it checked before it turns into a secondary infection.

Flea, tick & worm prevention

A Border out working hedgerows, long grass and woodland picks up parasites easily, so a steady prevention routine beats reacting to an infestation. Use a vet-recommended flea and tick product on a regular schedule, options include monthly spot-ons, sprays and tablets, and some combination products cover several parasites at once. Ticks are a real concern for a ground-hunting terrier, and prompt tick removal lowers the risk of Lyme disease and other tick-borne infections.

Worming covers roundworms and tapeworms, with lungworm a growing threat in much of the UK. Lungworm is carried by slugs and snails, which a nosy terrier may eat or lick accidentally, and it can be serious, so make sure your parasite plan specifically includes lungworm cover. Most adult dogs are wormed every three months, though your vet may adjust that based on lifestyle and local risk.

Puppies need worming more often, typically every two weeks until around 12 weeks old, then monthly to six months. Check every product against your dog's current weight, and never use a cat product on a dog. If you are travelling abroad, tapeworm treatment is a legal requirement for re-entry to the UK within a set time window before return.

Medications & dosing

Because Borders are small, dosing accuracy matters more than in a big dog, since a small error is a large proportion of the correct dose. Almost every canine medication, from wormers and painkillers to antibiotics, is dosed by body weight, so an up-to-date weight from the vet scales is the starting point for getting it right.

Never give human medicines without veterinary direction. Common painkillers such as ibuprofen and paracetamol are toxic to dogs, and even canine anti-inflammatories need the correct dose and a check that the kidneys and liver can handle them. This matters even more in a breed prone to idiopathic epilepsy: a dog on anti-seizure medication needs consistent dosing and regular blood monitoring.

Keep a simple record of what your dog takes, the dose and the date, especially if more than one person feeds and medicates. Finish prescribed antibiotic courses fully, and store all medication out of reach, a determined terrier will chew through a pill packet if given the chance.

Grooming & coat care

The Border's coat is short, dense and wiry over a soft undercoat, designed to shrug off mud and rain. It sheds relatively little day to day, which keeps everyday maintenance low, a weekly brush with a slicker keeps it tidy and removes loose hair and debris.

The one job that defines Border grooming is hand-stripping. Twice a year or so, the dead outer coat needs to be plucked out by hand (or with a stripping knife) rather than clipped. Stripping keeps the correct harsh texture and the weatherproofing that goes with it, whereas clipping softens the coat over time and can dull the color. Plenty of pet owners learn to do it themselves, others use a groomer who knows terrier coats.

Beyond the coat, keep on top of the basics. Check and clean the ears, especially in an allergy-prone dog, trim nails when you hear them clicking on hard floors, and brush the teeth several times a week to hold off the dental disease small breeds are prone to. Bath only when genuinely dirty, over-washing strips the coat's natural protective oils.
