LOL well, see, my child was born and many rotties came after, a few while she was an infant or toddler. But you are a breeder, I am a breeder, we have systems worked out and tons of experience. But that said, my child came first and I know that the pups I kept did not get as much attention as those that came after she was past the toddler stage. We adjusted, but was it ideal? No.
And when I am placing a rescue or my own, and I can choose between a family with a baby or equally good family without one, I'll go with the no baby. If they get pregnant after the fact, the pup is settled into the routine.
In fact one of my best owners flew from WA state to GA to pick up her pup. Less than 6 wks later found out she was pregnant. But she had more Rottweiler experience than I had, grew up in Germany doing schutzhund with her dad. In fact, she was the ONLY person I felt competent to take my male Rottie if I died before him. However, even in her home, HER pup ended up being her son's dog because he was the one (due to her being pregnant and then the baby) who actually gave the dog most of his training and attention.
Like I said, there are exceptions. But do you really think it is ideal to have baby and NEW dog or puppy?
