The F-Litter pups are enjoying the taste of a good deer liver. They are 6.5 weeks old. I am still teasing them with the livers. I also extend the liver a short ways away from them and hide it. I want to see the pups use their noses to find it. At this age that is what they do. They are not looking with their eyes to find it. That is what we are are after. So far I am happy with all of their progress.
