Pecos21, I have gotten ringnecks from these dogs out of every litter I have ever had. Not every pup, but several ringnecks in each litter. My dogs are cow bred but I used them on both. I managed a ranch here in Fla for years, running 500 cow/calf pairs. We used the same line of dogs for cattle as we hog hunted. In fact, they were often littermates.
Here is a pic of my Spur male, a yellow ringneck. He is coming 2 years old, is sired by my Monkey dog (which is Partin bred) and out of my old cow dog female Chelsea(who is now deceased). Spur doesn't have the bite my other dogs have, but he will probably live a long time because of that......he is more of a bay dog and less of a rough catchy dog like I am used to. He is out of Monkey's first litter.
Hate to hear about you losing your dog, if you saw my pens you would know why they are the way they are. When I put one in my pens, they will be there when I get home......no chain link pens here. Heavy duty welded panels, on concrete floors with tops on the pens. I lost one dog years ago (the best cow dog I ever owned) by her getting out of a pen and I swore that wouldn't happen again.
