Otters live both on land and in water. Their breeding dens are located in some secluded spot by the side of a lake or river, with easy access to water. Their dens were often co-habitated by water rats or other vermin. Otters are capable of remaining for a considerable time under water, where they skilfully take great numbers of fish, one at a time.
An Otter Hunt

At the slightest threat, the otter would dive into the water and rapidly swim to escape. Sometimes huntsmen, together with terriers entered the otters' den as pictured. When hunted with dogs, the brave, older otters would obstinately defended themselves, biting the dogs and not quitting however badly they might have been wounded. But, with the assistance of Otterhounds, the vermin was driven to swim towards the huntsmen, positioned wading at least knee deep in water within the rivers or streams, with nets or spears.
An Otter Hunt
The hunt could go on for hours. Eventually, an often exhausted otter, usually accompanied by water rats was eventually caught by either by the dogs or in huntsman's nets. The brave otter's courage made them the victim of blood-thirsty 'sports' popular in Britain during the 1800's. So in 1906, otter hunts were banned in UK.
An otter's legs are short, but remarkably strong and muscular. On each foot there are 5 toes connected by strong membranes, like those of a waterfowl. The otter has an oval-shaped head which is broad, and the eyes placed so they can see every object above it. Its ears are short with a narrow orifice. Their tail tapers to a point so it can be used as a rudder. Their fur is deep brown.
Because the otter lives mainly on fresh fish, it destroys them in great numbers. While chasing a fresh fish, it will even swim against the current. Once a fish has been caught, the otter immediately drags it to the shore, and unless very hungry, devours only the body, leaving the remainder in pursuit of another fresh, whole fish.
There are many recorded cases where otters have been tamed. If taken sufficiently young, sometimes even suckled by a bitch, they would follow their masters, even answering to their name. Used by huntsmen to catch fish, they could take around 8-10 salmon a day! A tame, well trained otter could even work with dogs, driving trout and other fish towards the net.
The Role of the Terrier
Otterhound c 1886
Otter Hunting was founded on these two types of dogs:
1.The type of terrier that existed in the North of England at that time, which was adept at entering otter dens and bolting its quarry.
2.The Otterhound, a hairy powerful hound with large ears and an oily water repellent coat somewhat like the dog on the right that was often used for hunting otters in the streams at that time. In Devonshire, the description of this dog was he had:
'a Bulldog's courage, a Newfoundland's strength in water, a Pointer's nose, a Labrador's sagacity; the speed of a Foxhound, the patience of a Poodle, and the artfulness of a sheepdog.'
How the Terrier Worked
Airedale Terriers c 1900
In the streams around Yorkshire, huntsmen required a terrier that filled the dual role of having the instinct of going to ground as well as being capable of swimming. The terrier was required to enter otter's den and bolt any vermin, which usually included both otters and water rats, into the stream. This gave rise to the terrier and the Otterhound being crossed, which became the Airedale Terrier we know today.
