This is a West Virginia Water Dog. Eddie caught one today. Unfortunately I had to kill it because it swallowed the hook and he couldn't get it out. It was suffering.
It is the first water dog I have ever seen. It was neat. It was about 8 inches long. They grow to about 3 foot or so I have heard. I looked it up on the internet. They can be kept in aquariums. I wanted him to leave it on the hook and use it for giant catfish bait but it was time to come home.
