Dog breed · Ireland
The Glen of Imaal Terrier (Irish: Brocaire Uí Mháil) is a rare Irish dog breed from County Wicklow, Ireland, and one of four original Irish terrier breeds native to Ireland. It is sometimes called the Irish Glen of Imaal Terrier or the Wicklow Terrier, and the name of the breed is often shortened by fanciers to just Glen.It is bred for hunting vermin and general farm work, the Glen is known for its strength, low stature, and unusually quiet nature for a terrier. The breed was recognised first by the Irish Kennel Club in 1934 and most recently by the American Kennel Club in 2004. The Canadian Kennel Club voted to fully recognise Glens in 2017 after the breed spent years on the Miscellaneous list; approval by Agriculture Canada is pending.
Once nearly extinct, it was revived in the 20th century and is now still considered to be one of the rarest breeds of dog (in the US, living registered animals number in the hundreds) and the least-known Irish terrier breed. It is considered a vulnerable native breed by the UK's Kennel Club, which tracks breeds in which fewer than 300 puppies are registered each year. The current global Glen population size is estimated at 3100.
Temperament And Behavior: Glen of Imaal terriers can be energetic and tenacious, but they tend to be more even-tempered, more easygoing, and less vocal than most other terriers. While they love activity, they are not demanding, and are happy to relax by their owner's side.
Their bark is deep and authoritative, like that of a much larger dog, and they are said to be good watch dogs.
The "Glen sit," in which the dog sits on its hind end and holds its entire body vertical, is a posture not commonly seen in other breeds.
As terriers, Glens can have a stubborn streak, but they are intelligent, learn quickly, and socialize easily. They are typically fearless and loyal, and are superb with people, including children. However, some can be dog-aggressive, especially when provoked.
Appearance: A "big dog on short legs," the Glen of Imaal Terrier is an achondroplastic dwarf breed. It is more substantial than might be expected from photographs; a typical adult Glen weighs about 36 pounds and stands 14" tall at the withers. The AKC breed standard specifies a height of 12" to 14" and a weight of "approximately" 35 pounds for males and "somewhat less" for females, with a length-to-height ratio of 5:3. Many champion Glens are larger than breed standard, with some individuals exceeding 40 or even 45 pounds. With three growth stages, a Glen can take up to four years to reach full maturity.
Glens have a large head, with rose or half-prick ears; short, bowed legs; and a straight topline that rises slightly toward the tail. The shoulders, chest, and hips are sturdy and muscular (the AKC breed standard specifies an impression of "maximum substance for size") and the front feet are turned out. The breed is considered unrefined, with antique features that were common in early terriers but which have since fallen out of favor with fanciers and breeders.
On their back, Glens have a unique double coat that is wiry with a soft undercoat. The head, sides, and legs have only the softer coat, which typically develops a degree of waviness. The color of the coat may be wheaten or blue (the latter usually with brindling), with both wheaten and blue encompassing a range of shades. Other colorings do occasionally occur in Glens (including a mixture of wheaten and blue referred to as "grizzle" and a "blue and tan" that is blue on top with wheaten furnishings) but these rare variations, while not disqualifications, are not favored by fanciers.
Wheaten Glen of Imaal puppies often have black highlights in their fur, and when young may show a "dorsal stripe" of darker fur down the middle of their backs, but this usually does not appear in their adult coat.
Health: A genetic test is available for progressive retinal atrophy (type crd3), a congenital disorder that gradually results in blindness beginning at about five years of age. As blindness from this cause did not become apparent until well into the breeding years, it was difficult to breed out this trait before the advent of the test. Completely eliminating the defective gene will be tricky even now, as breeding only clear-to-clear would severely restrict choices in an already small gene pool. It is straightforward, however, to produce litters that will never be affected by this type of PRA, even though some individuals in the litter may carry the gene. (Because the trait is recessive, animals with only one copy of the defective gene do not develop PRA, and it is necessary only that one parent be clear to achieve this.) Responsible breeders use the test to plan PRA-free litters and continue to test their animals' eyes annually to validate the test and to monitor for other eye problems.
Heart problems are virtually nonexistent in the breed. Some Glen of Imaal Terriers suffer from allergies and skin itching, especially on paws, the typical problem with paws is redness, itching and sores during spells of wet weather. The Glen is not generally affected by the back problems common in certain other long-backed breeds. Hip dysplasia, though occasionally seen, is usually mild, and does not often result in lameness due to the breed's typically muscular build. Responsible breeders use OFA or PennHIP evaluations to ensure that their breeding stock's hips are healthy.
Because they are front-heavy and achondroplastic, young Glens are particularly susceptible to growth plate injuries that can significantly affect the development of front leg bones. Owners are advised to discourage their Glens from jumping off sofas, chairs, and beds until at least a year of age and to consult a veterinarian at the first sign of limping.
After the age of 12 months, Glens generally do best on a diet lower in protein than other breeds.
