AKC 6 Month old black lab - Male in Cherokee, California For Sale

He's an amazing puppy, but my other dog is not taking to him well, apparently she has no patience with puppies. I paid $500 for him and got his shots all utd and he is neutered already, his dad was 90lbs, he is already 45lbs at 6 months. He was the biggest in the litter. He is solid black, super happy and healthy, and like most labs LOVES water :)
Looking for a good home for him, he loves kids and all people and animals. Is fully house trained and is working on sit and lay down.
Asking $400 for him, feel free to make me an offer as well.
His full AKC registration papers will go with him as well. He would make a great hunting dog.
