I refer to them as puppies for much longer. And it is a bonus plan when they will live together for a little extra time. I don't put a lot of stock in it in the long term but it does give the warm fuzzies to see them fire up early on.

The last litter I had was fine til the last two were together. Three and four in the pen all was fine. Down to two and it looked like both were trying to establish themselves. 12 weeks and they were taking hold like grown dogs with bad intentions. Stayed mad for a long time after they were separated. The male has been 'grown' since then, or at least he acts that way.
