Breeding for Results...

Since your dog is a reg old joe out of the liter if he is heavy heavy line are inbred what that is telling you is your dog is as tight as he needs to go much more it will go stale and is begging for a outcross to refresh his family blood so that it can work .

If your old reg joe dog is not heavy heavy family bred and is made up of a bunch of different lines of dogs then it is just a shot in the dark because you don't know which direction to go are were his good came from are were his bad come from. This is the advantages of family line bred dogs you eliminate it down to just one two are three different lines so you can work with it and over time tell which line is giving you what and which line is not. This is why it is such a shot in the dark with best to best sometimes when breeding best to best it is just the roll of the dice , it either works are it don't and if it does work you don't know why till you start a family on the cross you just made .
