If its my litter, I want to wait it out as long possible before I decide which ones I like.
If its not my litter, I dont want to pick after 9 weeks. I like my pup with me earlier.

I like to take them out and see how they react and play with them a little. get them to chase the toys... look at the different builds of the dogs and see which ones are built like or structured like certain family members. My last litter I could tell differences at 6 weeks based on how they were acting with eachother in the pen. But I mean, everything is subject to change cuz they are just pups. If I only got one choice though, I aint gonna select the one with the attitude and demeanor i like the least out of all thats available.
