How long do yall keep a pup before culling

I had a litter last July I kept 3 of the 5. I named them Captain Gus and Lori from lonesome dove and they have really lived up to their names.

Captain is the hardest goin gameiest pup I have ever owned he has yet to strike his own hog but is always right there when it happen. He's a good hard working dog!

Gus is the laziest dog I have ever owned don't wanna do anything. The other night the dogs bayed and as I was walking up he came outta the bay Justa wagging his tail!

Lori is nothing but a white trash whore she hunts hard for a little while then will try to lay up on ya but will go to every bay and bay hard and look like an old pro. She has bad kennel manners like I have never saw before she will crap all over the place in her barrel in her food and water bowl it is insane!!!

Captain is a keeper!
Gus is more than likely getting culled July 5th unless he improves drasticly
Lori is more than likely gettin culled due to kennel manners.

I'm goin to wait til they are all a year old.
What I'm gettin at here is there are way more factors in the culling game than just huntin ability.
