Couldn’t help but grin when I read your post about the dog fish. When I was about 7 or 8 years old I was over in the “bottoms” in pool # 7 fishing for bluegills. I latched unto something that about jerked the pole out of my hand. Low & behold it was a dog fish, that much I knew. I grabbed him behind the gills and he cooperated with me 100% by opening his mouth so I could get my hook out. Like a dummy, I made the mistake of getting a little too close to that trap. Just as I was unhooking the hook, Fido clamped his jaw down on my finger. As luck would have it, his teeth slid down my finger nail and that of course allowed him to clamp onto that piece of flesh there at the end of my finger. I’m here to tell you now, I’m 71, that hurt worse than anything I ever encountered any time the rest of my life. Needless to say, I never got that close to a dog fish again, ever!
