Number three was the smallest at two feet...the third cottonmouth killed in our front yard (down by the pond). Hubby was just sitting in his lawn chair and our six-month-old Border Collie started barking and having a fit. He walked over to see what it was and BAM got it with a big rock (he said he'd been keeping the rock down there for just this purpose). UGH...he brought it to the house on a stick so I could see it (now I'll have snake nightmares tonight). I am just grateful the dog or the hubby didn't get bitten. The dog that was bitten by the huge cottonmouth earlier this summer wouldn't come close to this one. Smart doggie!
