Border Terrier
BOR-dur TAIR-ee-ur
Affectionate, Happy, Plucky, Obedient. Originally bred for fox bolting (following foxes into their dens).
An adult Border Terrier weighs 13-16 lbs (male) or 11-14 lbs (female), needs 330-620 calories daily, and lives 12-15 yrs. As a small breed, every calorie and every ounce of body weight matters proportionally more. The breed's primary health watch is patellar luxation. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Border Terrier needs 330 to 620 calories per day. An average male (14 lbs / 6.6 kg) needs around 490 kcal; a female (12 lbs / 5.7 kg) roughly 440 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
Smaller breeds generally live longer than large breeds, and the Border Terrier benefits from this with a life expectancy of 12-15 yrs. Their compact frames create their own set of vulnerabilities. The breed's primary health concerns are patellar luxation and hip dysplasia, which responsible breeders screen for before breeding.
Exercise and activity
45-60 minutes daily. Surprisingly athletic for their size. Enjoys long walks, hiking, and earth dog trials. Terriers are diggers, chasers, and independent thinkers. The Border Terrier will investigate every hole, chase every squirrel, and test every boundary you set. Provide outlets for natural terrier behavior: digging pits, earth dog trials, agility, and puzzle toys that require problem-solving. Without sufficient exercise, the Border Terrier is likely to develop destructive behaviors, excessive barking, or anxiety. This is a breed that needs daily commitment to physical activity.
Care and traits
Border Terriers have a wiry, dense, weather-resistant coat. Origin: Anglo-Scottish border region.
One of the healthiest terrier breeds. Their wiry coat needs hand-stripping twice yearly but is otherwise low maintenance. Good all-around family terrier with fewer attitude problems than many terrier breeds.
Their small size makes them suitable for apartment living, but they still need daily outdoor exposure and socialization. Small dogs are vulnerable to injury from rough handling, falls from furniture, and confrontations with larger animals. Supervision around young children is essential.

Frequently asked questions
A healthy adult Border Terrier requires between 330 and 620 calories daily. A 14-pound individual falls near the middle of that range. Small breeds have higher metabolic rates per pound than larger dogs, so they need calorie-dense food relative to their size. Active dogs need more; seniors and less active individuals need less. Use our calorie calculator with your dog's actual weight for a personalized number.
Males typically weigh 13-16 lbs (5.9–7.3 kg). Females run lighter at 11-14 lbs (5.0–6.4 kg). Small dogs hide extra weight under their coat. Pick them up regularly and feel for rib coverage as your most reliable body condition check. Run your hands along the ribcage: you should feel ribs under a thin layer of flesh without pressing hard. From above, look for a visible waist narrowing behind the ribs.
Among Border Terriers, patellar luxation is the condition most frequently diagnosed. Patellar luxation (slipping kneecap) is common in this size range. Maintaining a lean weight reduces stress on the knee joint. Moderate, consistent exercise strengthens the surrounding muscles. Severe cases may require surgical correction. Other conditions seen in the breed include hip dysplasia, heart defects, seizures. Not every Border Terrier will develop these conditions, but knowing the breed's tendencies helps you and your vet monitor proactively.
This breed needs genuine exercise, not just a quick walk around the block. Aim for 45 to 60 minutes daily. Good activities for this breed include digging games, earth dog trials, fetch. Indoor play and training sessions count as legitimate exercise for dogs this size. An under-exercised Border Terrier will find outlets for pent-up energy, often in ways you will not appreciate: chewing, barking, digging, or restless pacing.
