I am going to be taking a look at a 4 week old litter of British labs, of which we have pick of the litter of the 3 yellow females this weekend. Do the pups show any personality or character at 4 weeks old yet? I'm not sure if the breeder is going to push for me to pick one out but I would think it would be best to wait. At what age have all of you picked your pup out? I will be bringing it home at 7 weeks. Thanks for any advice or help!
