I just finished a quick read through of "Total Recall" and have a couple of questions. 1. Is there a reason why 5 pips are suggested for recall? Three seems a lot easier, but I expect there is a reason for recommending 5. I just don't know what it is. 2. How do you deal with this pretty detailed training in a two dog household. We normally train, walk and play with our two dogs together. It is not hard to work on Sit, Stay, Down etc. with both dogs close together, but I don't think that will work with recall, at least not in the early stages where there are supposed to be no distractions.
