I also had a friend's Jack Russel that used to go coarse fishing with me and he would watch the float or rod tip and any movement he would bark. When I retrieved any fish, he would dive in and grab them in the shallows and I will never forget when he did this with an eel. As hard as he gripped, it would still slip through his jaws and I can still see his eyes and the muscles on his jaws bulging in an effort to keep hold. In the end, he let it slip to the ground, turned and pissed on it. Honours even!
Terry.
