Short Legged Terriers

This section explains the short legged construction of terriers whose legs have been shortened to allow the dog to bear his weight on his chest, leaving the legs free to dig. These terriers' bodies also had to be extremely flexible, allowing them to work within the confines of tunnels like the setts created by badgers, as the section below explains.

The Short Legged Terrier Breeds

Here are the 12 terrier breeds which have front legs shortened to varying degrees. The following list in descending order is from from those with the deepest chests to those which are built on top of their legs (which should be perfectly straight much like the long legged terriers). This is especially evident with the last breed on the list, the Jack Russell Terrier, where the shape and lack of depth of the ribcage is clearly enunciated in the Breed Standard by the requirement of "spanning a terrier".

Glen of ImaalGlen of Imaal

The most extreme is the Glen of Imaal, where the chest is so deep the front legs are allowed to have a slight bow. The Scotty is next where the breed standard calls for this dog's ribcage to be 'hung between the forelegs'. Then comes the Dandie and Skye to the Sealyham whose chest is placed just between the forward facing forelegs. The remainder of the breeds are built more on top of their legs.

How Short Legged Terriers Dig

Those terriers with the deepest chests have a unique digging action whereby they lie on the spot where the hole is being dug and move the dirt to the sides of their body and then wriggle through. The anatomy of a short legged terrier has to also allow the dog to retreat with the long gradual slant of the sternum also helping it to slide more easily over rocks and tree roots[1]. Thus when a dog has a deep chest, a slight bow in their front legs actually assists with unique 'side digging' action[4]. This digging action is particularly useful when the dog is working within the confines of a burrow as the dog only has to not only make his way into the burrow, he also has to be capable retreating backwards.

With the exception of the Glen of Imaal, the remainder of the short legged terriers should have front legs as straight as is possible with the elbows working close to the sides just above or level with the sternum.

The digging action between terriers with deeper chests differs from the remainder of the terriers, both short and the long legged which, when digging push the dirt backwards between their widely placed back legs.

Judging a Short Legged Terrier

Although all these Breed Standards except the Glen of Imaal call for the front legs to be as straight as possible, the slight amount of bow or outwards turn of the front feet referred to is only to be tolerated on the Scotty, Dandie Dinmont, and the Skye.

Achondroplasia or DwarfismAchondroplasia or Dwarfism

But excessive bow of the front legs can cause the front feet to turn out too much as shown. This is undesirable in any terrier and could indicate the presence of the genetic abnormality of achondroplasia or dwarfism[2].

So, it is extremely important that that breeders and judges always check the depth of chest of short legged terriers and look for legs as straight as possible. Because excessively deep chests can also cause this incorrect bow in the front legs[3].
