What does waterdog mean?
Waterdog is an uncommon noun with several established but distinct uses. One modern use denotes a North American aquatic salamander of the genus Necturus, a group that includes mudpuppies. In older North American usage, it was also a name for the river otter. A third, largely historical sense referred to a dog trained or bred to hunt otters in water, a sense associated especially with British and earlier English hunting traditions. The word is therefore best understood through its context: a modern wildlife term, an old name for an elusive mammal, or a piece of hunting vocabulary. Although waterdog can sound like the name of a modern breed, that breed is identified separately as the Portuguese Water Dog. Its particular interest lies in this layered history, preserving both the language of otter hunting and a compact label for creatures closely associated with life in fresh water.
nounAn aquatic salamander of the North American genus Necturus; also, historically, a North American river otter or a dog bred for hunting otters in water.
- An aquatic salamander of the genus Necturus, especially a mudpuppy, chiefly in North America.
- A North American river otter, especially in historical usage.
- A dog trained or bred to hunt otters in water, now chiefly a historical sense.
"The guide identified the large, spotted amphibian as a waterdog, commonly called a mudpuppy."
"Wildlife guides may call the mudpuppy a waterdog because it is an aquatic salamander with external gills."
"In older hunting literature, the waterdog was valued for pursuing otters in rivers and streams."
The regular plural is usually written as one word; historical writing also commonly uses the open form “water dogs.”
"Researchers found two waterdogs in the shallow water."
The word has named both the hunter and the hunted: a waterdog could be an otter-hunting dog, while the river otter itself was also called a waterdog.
