A Terrier, Terrier: the Border Terrier has the head of an otter and the spirit a cobra, fearless and fast.

A working Terrier, medium sized, tough as nails at the field and different to other Terriers for its head similar to an otter’s. The working Border Terrier stands between 33 and 39 cm. and the female between 29 and 35. It has a medium bone structure, sturdy, although it is relatively narrow around the shoulders, body and hindquarters. One of its traits is the hard coat, very resistant and close-fitting (never wavy or curly); the Border Terrier is displayed at its natural state, only slightly groomed. The eyes are described as “full of fire and intelligence”. The ears are small and “V” shaped; are not high inserted, but fold forward, close to the cheeks. The muzzle is short and full; a moderately wide curve is desired over the stop. The neck is clean cut and muscled, widening gradually towards the shoulders. The back is strong and doesn’t sink behind the shoulders.  The ribcage is well let back, not too rounded; the inferior outline is quite straight. The tail is moderately short, thick at the base and narrowing. The hinds are strong and typical; the femur is long. The Border Terrier can be red, gray and tan, blue and tan or wheat; a dark muzzle is desirable; white is allowed at the chest but not the feet.
Be it inside or out of the house, the Border Terrier loves to be close to its people and protect them from vermin. Although it has a temper, the Border Terrier is a sensitive company dog.

This simple and brown dog is one of the best kept secrets. The Border Terrier is a fantastic family dog, unusual, full of charm and life. Since it is 110% Terrier, it is an exterminator and will chase mice, rabbits, squirrels, etc. Although the family cat is safe, other small company animals aren’t. The owner must have a fenced yard (high enough so it can’t jump, and with the fence well underground so it can’t dig out). Extroverted, reliable, sensitive, friendly and affectionate, the Border Terrier is a free spirit and likes to make its own decisions. Its training needs to begin early. Due to its free hunting spirit, it believes it has to look for its own dinner, for which walking it is interesting. Since it doesn’t have bad habits or character, the Border Terrier gains fans amongst the sensitive type, which are not moves by a plush coat or fad. Many owners opt for a second specimen, to keep the first one company.
Choose a puppy with a balanced structure at eight weeks. Normally after ten or twelve weeks the legs can seem shorter, but it will soon outgrow this phase.

The Border Terrier weighs 280 g. at birth. It matures slowly for a small dog, and doesn’t reach its complete adult structure until after a year and a half, although in some lines, a little before. Growth differences can show that a puppy will not be a show quality specimen. The buyer should seek a well balanced puppy. A Border Terrier weighs between 1.750 and 2.5 kg after eight weeks. The typical rough coat should be present after three months, although it turns harder as the dog grows and sheds its puppy hair. Character changes are usually not a problem, although consistent socializing (with people and dogs) is vital to prevent it from becoming introverted. A shyness period is frequent, and the owner should simply be patient and stimulate it, while it continues socialization. However, the owner should avoid excess stimulation to prevent an unruly teenager, who could continue that way as an adult. Testicles could take six months to descend.
The Border Terrier matures slowly, and white patches at the chest diminish with age. Avoid white patches at the fingers for a show puppy.

The Border Terrier is a fun canine partner, with 15 year longevity.
With a good socialization and abundant constructive exercise, including biting bones, the Border Terrier is a happy dog, with a good temperament.

Besides the necessary Terrier “stripping”, the Border Terrier is easy to care for, due to its small size as well as its resistant nature. Congenital heart problems have been reported as well as hip dysplasia and progressive retinal atrophy; and, although its incidence is low, we should demand X – rays of every reproduction specimens. Puppies should be examined at early age and after every year for heart murmurs and other possible problems.

When small the puppy is brown and the tan undercoat gradually grows in.
