Still working with my first pup, she was born Feb 16th of this year and I picked her up in April on the school vacation week. She came to work with me everyday from mid April until mid June. I was fortunate enough to be able to bring her with me and I trained 2-15 sessions each day, obedience is always, but more formal things, sit/stay, whistle training, heel and such. I read books from Milner and Wolters and followed a lot of their suggestions.
Long story short, Pearl has done outstanding to date. She will be 9 months Nov 16th and has 63 retrieves this year both inland and coastal.
I would look and buy now and your pup will be even more ready and stronger come next fall than waiting until spring and hunting a younger dog. Once spring and summer hit you could really start water traing and such too. Just my two cents from a new lab owner.
Pearl came from Labman63 here on the forum. He did a duplicate breeding of Pearl's and I believe has only two females remaining, from a litter of 12.
Here are a couple a pictures of Pearl, just to get the juices flowing. By the way, she is a family dog too with great temperment.
