Life with a Border Terrier
The Border Terrier is an active breed that needs plenty of exercise and mental stimulation to stay content. As a small dog (5–10 kg as an adult), it is quick to learn and usually responds very well to training, which matters most in the first year while good habits are being formed. It also will bark to alert you but is not usually excessive.
Coat care is a big part of day-to-day life with this breed: its coat benefits from a regular weekly brush to stay tidy, and it sheds a moderate amount, with heavier shedding at coat-change times. Around the home, the Border Terrier has a reputation as an excellent family dog and is typically gentle with children and usually settles in fine alongside other pets with proper introductions, though every individual dog is different and early, positive socialisation makes a real difference.
Weather is worth planning for too – this breed manages moderate warmth reasonably well but still needs care on hot days. Whatever your plans for exercise, feeding or budgeting, the tools below are pre-loaded with typical figures for the Border Terrier so you can get a quick, personalised estimate.

Daily exercise needs
As a working, sporting and herding breed-type dog, the Border Terrier typically needs about 90–120 minutes of exercise a day, split across one or two walks plus some off-lead time or play where possible.
Puppies, seniors and dogs recovering from illness need much less – see how much exercise does my dog need for a plan by age and health.
Estimated UK costs
Ongoing costs (food, insurance, routine vet care, flea/worm treatment, grooming and extras) for a Border Terrier typically run to around £81–£110 a month, or roughly £12,150–£16,500 over an average 12.5-year lifetime, not including one-off costs like purchase price, neutering or equipment.
These figures are UK averages and will vary by region and lifestyle. See our cost-of-ownership guide for a full breakdown you can adjust yourself.
Health conditions to be aware of
Like all breeds, the Border Terrier has its own set of conditions vets keep an eye out for. Knowing about them ahead of time means you can ask the right questions, consider health screening, and choose insurance cover that suits.
- Canine epileptoid cramping
- Heart murmurs
A breed being prone to a condition does not mean your pet will get it. Ask your vet about screening and insurance.
