My Jack Russell, Abbey, was throwing a fit night before last beside the garage. I went outside to see what she had cornered. I saw the snake trying to scoot across the concrete pad just outside of the garage. It was moving like a sidewinder, but wasn't getting a lot of traction. She was grabbing it's tail and pulling it backwards and as it was trying to strike. It was a 20" Copperhead snake. My Blue Heeler Buster, just barked a bit far enough back to stay out of the snakes range. He had been bit the year before and stayed overnight at the vet's office. His head got so big, and it didn't go down completely for about 3 days.
I just scooped Abbey up, and took her in the house because she intended to kill it. I knew she would get bit in the process, so I put a stop to her fun.
I find Copperheads around the house quite often as I live in the middle of nowhere, and there is a ditch filled with running water that surrounds the property.
When the hay is cut, on the other side of the pasture, there are always quite a few dead ones found close to the ditch area where the disc mower cuts them up.
I can always tell when Abbey has killed a snake because she will have red whip marks over her body. she She does pull a lot of the skin off and I think she may roll on it. She could be slinging it back and forth and it hits her body. I have not caught her in the act yet. She looks like a red brindle dog.
