I am 63 now and have had Dogs all of my life but have never understood them in the way I am starting to now that I am going through the training. I lost my last 2 dogs a year ago and am moving through this so that I will be prepared when I chouse my next Best friend, It will be a Pup and the right breed for RV travel and a verity of climates and suitable for Hiking (my favorite pastime). I'm so happy to have found this information when I did. JB
