i would never get another puppy until the older dog was at least a year old... this is just my personal prefrence because i wont have to deal with two puppy puppies at the same time, the older one can "mother" the yonger one, and i wouldnt want them to get too attached to each other like they are littermates and leave me out of the "inner circle"

... again this is just my personal preference and i honestly dont think i will ever have two dogs at one time again (even if i did have teh opportunity)...... too much to deal with at one time with two dogs with everything else in my life
