Great tread , we used to hunt with an old guy 20 years ago he has passed awey now he told us about hunting otters years ago, he was a water bailiff and used an irish terrier to hunt otter when he was out doing his rounds, he said that the irish terrier was a great dog for otter but he always said that no dog was able for an otter when it took to water he saw an otter take an irish terier under the water and spin him around until the dog was nearley dround he had to wade out and save the dog before the otter drowned it.
