I've had a Yellow Lab for 5 years now. The first year I had limited time to work with her before the opener. She was 9 month old when we got her in Aug. 2000 from one of the dog rescue organizations here.
The young guy who had her and a male Y. Lab had supposedly planned to breed her and sell the pups. Instead, we were told he kept her and the male lab locked in a closet with a screen door on it all day and the idiot chased girls at night. The dogs were obviously neglected, until the dad of this 20's guy called the rescue place to come get the dogs.
Molly (our lab) took to hunting, retrieving (water and land) and learned to obey and worked "like a dog". Even when she'd be tired at the end of the day she still wants to get out of the kennel when we stop to get out at the next hunting slough or field. I couldn't ask for a harder working, better dog. She's a sweet temperment dog with people and most other dogs, too.
She has a heart and will to please. I wouldn't give her up for any money.
I'd give Yellow Labs a look, too, if I were you.
