After using a cattle prod Sunday while help my SIL work his cattle I'm not sure I'd use one on a dog. When I had to prod a 1100 Lbs cow to move her into the squeeze shoot, & she was NOT pleased but moved when I just poked her with a plastic paddle. A cow's hide is much thicker than a dog's skin so I think it might be too much of a shock. Sending many get wet wishes to you & Betty. I'm with Jennifer that maybe the other dog has a medical problem.
