If you are asking how to choose which ones to keep and which ones not to keep...... I personally would wait until they are old enough to try on a hog, about 4 months old. Some people cull earlier but I like to see how they react the first time they encounter a hog. Then at around 6 to 7 months, take them to the woods with an older finished dog to see if they will get out and hunt or not. That is how I cull. Hope this helps.
