Is There Such Thing As A Dog Fish?

The name dogfish is applied to a few different fish in the sea.

Mostly it's used as part of the common names of a small number of species of sharks. The relevant animals occur in the Mediterranean, Pacific and Atlantic. Very common in UK waters is the Lesser Spotted Dogfish (also called the Small Spotted Catshark), which reaches a length up to 1m long. Basically, it's a small spotty shark.

Many other sharks are called dogfish. This common name does not denote any true relation between the different sharks that get it. But usually it refers to relatively small species.

Dogfish may also refer to a fish in the Bowfin family, Amia calva. This is a primitive fish (not a shark) that has not changed since Dinosars walked the Earth. It lives in the North Atlantic, can grow up to 1 m long, and is a popular sporting fish, because it puts up a terrific fight in order to be caught (it is not considered tasty, however).

Yes there is.

... Hmm, caught a fresh water fish "once" that looked similar to a bullhead cat fish but wasn't. Bullheads, northern pike, crappie and turtles were a common site and catch in the lake.  The difference in the two of this once time only catch was the head was large, it had roundish cheeks with what looked like whiskers, and made a sound like a dog bark.  I didn't know what it was.  Others were there and said it was a dogfish. Sound Odd? It's no where on record with in that U.S. State nor anywhere else thus far, and I've never seen it again. However, I've seen what ever it was, once.
