I doubt many hunting dogs are abandoned. They have to much time and money invested in them. Some hunting dogs are almost like children to them. Of course there are exceptions. Most, not all, hunting dogs will have a "tracking collar" on it. Sometimes people will take the "tracking collar" off just so the hunter cannot find their dog. I found mine in a river one time. If there is no way of tracking them, then it may take a while to find them. Many times they have more than one to find. If the dog follows somebody away from the area, that makes it worse.
