I learned a few years ago that field mice actually have a similar scent to pheasants. A trainer friend of mine taught me this. He said it was very common for young dogs to point field mice because of that. Really helped me have better patience when my pup started working field mice.I was hunting with a good friend and his new German Shorthair. This dog was still in the training phase, and had little field time. He did keep his nose to the ground, but that day the only thing he would hunt, and find, were field mice! I was teasing my friend how he had a pretty good mouse dog on his hands. Sadly, that dog developed serious health problems and had to be put down less than a year later. I have only had the chance to hunt with dogs about a half dozen times. I will say that I got more enjoyment watching the dogs work than I did in shooting pheasants.
