Reminds me Queen. She was mixed hound--and possibly something else. Her color was dirty black with markings like a Black and Tan. The markings were not a rich tan but creme colored. She had a large white spot on her chest. She started her hunting career as a combination Squirrel and O'possum dog around Okmulgee, Oklahoma. It was said of her that a person could take her to the woods in the evening, tree 25 'possums, and be home and have the skinning done by 9 p.m. That may have been an exageration, but she would tree 'possums and Squirrels.
I was in my lower teens when the older man that I hunted with, Al, bought her for $35. She had just raised a big litter of pups and was terribly skinny and wormy. He promptly wormed her and poured the feed to her. Soon, she was almost too fat, and she stayed that way as long as I knew her.
With her up in good shape, Al drove to the bottom, parked his old Dodge pickup, and opened his dog box. She hit the ground moving and treed within a stone's toss of the truck--a 'possum. By the time Al got to the tree, Ole Blue, a straight Bluetick, started a 'coon trail. Al called Queen off her tree, and she went to Ole Blue. After that first 'coon experience, she stopped treeing 'possums and concentrated on 'coon until she got too old to keep up with other dogs. When they would leave her behind, she would stop and start treeing 'possums. At my age, I understand the move.
But I digress. One evening, while hunting on the Deep Fork, she apparently encountered a Cottonmouth. (We didn't know the kind of snake for sure, but we were in Cottonmouth habitat.) By the time she returned to the truck, her head was "big as a lard bucket."
With no treatment but rest, food, and water, she recovered completely.
During the several years that I hunted with Al and Queen, I had several well-remembered experiences. Once, after Al had a leg broken when a horse fell with him, we went out to a 600-acre bottom west of the Deep Fork west of Okmulgee and took Queen. He was wearing a cast and using crutches. We found a spot near the center of the Bottom, built a fire, and sent the old hound out. She went north and was gone for about an hour. She came back in, walked around the fire and us a while, then headed out south. In about another hour, she returned, walked up near the fire, and sat down. Al said, "Well, we might as well go in. There's nothing movin' tonight." She followed us back to the truck and jumped in the dog box. We drove back into town.
Don't sell Copperheads short when it comes to deadly venom. A friend of mine recently found one of her females dead in her pen. On inspection of the pen, she and her son found a Copperhead in the dog house. And I have lost two dogs in their pens to what I believe to be Copperheads. Snakes will go into the pens after rats/mice that feed on dog feed. That is especially true if self feeders are used. And I've known of people who spent as much as two weeks in the hospital after a bite by a Copperhead.
I have found snakes, and other animals, dead in pens: my Boston Terriers had dispatched them. I have a mean strain of the little screwtail dogs.
