Here is MY opinion, for what it is worth.
Yep take a good look at the parents and see how they interact with you when you visit. Do NOT try to make the deal happen. Be prepared to walk away if you can see anything that isn't quite right. Also when you pick up the pup, do the same with the pup in mind.
We had (3) labs in our lives.
The first one was a male that we did a non-existent job of socializing him with people AND other dogs. As he got older, he became very aggressive to others. He eventually ended up biting a little girl and we put him down. WE FAILED HIM.
Our second dog was a female that we socialized the dickens out of both with people AND other dogs. She was the most friendly dog and was an awesome hunter. I wish she was still with us she was that good. To this day, I still get remarks from people that knew her on how they miss her and how she was such a nice dog.
Our third dog was a female that we did a little different on. We decided to let the breeder keep her for the first 6 months and train her as I thought my work was too time demanding away (at the time) from home that she wouldn't get the training she needed. Perhaps I was wrong with my thinking. (?). Anyway to cut to the chase, they did an awesome job of training her as she knew commands like no body's business. But they NEVER socialized her with people and spent LITTLE time with her. She spent a lot of time with other dogs her own age. Anyway she was great around other dogs but had ZERO to do with people. She was scared of them. I worked hard with her for over a year but couldn't get her to become acclimated to people more, but wasn't having much luck. Bottom line, I took her back to the breeder and he gave me my full money back. It was so hard taking her back. But I thought it was the best for our family. ? Hard when no one else in the house felt comfortable taking her anywhere by themselves. Even on a leash. She was that scared of people.
My friend had a chessie/lab mix male. He said it was a very dominant dog. An awesome hunter. It listened to him. But would try to put his wife in her place. (Who is the top dog?) He said he would never get a chessie or chessie/lab mix again.
2400, so you do with my comments as you like. I wish you the best.
My broad advice is to get your pup at 8 weeks. Make it a house dog if at all possible to get it the most human interaction available. Then take it everywhere you go and get it to see people and other dogs. Start doing that right away at 8 weeks. Don't put it off. MAKE special trips to get it out and socialize.
Personally I would go with a pure lab. And not go with the mix.
Good luck my friend.
