OK, back on subject. I have heard of people who breed every heat (which I completely disagree with) and some who breed as you plan on with great success and no problems and then some who breed every other cycle. I myself chose every other cycle because I wanted to make sure Trixie had plenty of time to recover, let loose and be a rowdy dog....not that she
wasn't rowdy while prego

.....anyhoo...
I thing the back to back or skip a cycle would differ from dog to dog...depending on the ease of whelp w/ the bitch, time in between cycles, etc. Just ,02 from another 'beginner.'
Can't wait to see pics of your future pups.
