Bad paws/wrists

[Pit Bull Committed]

My 4 month pup has some sort of deformed paws. I am not sure if this a genetic issue or a diet/environmental issue. My pup is on a raw diet since the day I got him at 8 weeks old. The raw diet consists of chicken quarter leg/ with bone, beef intestine, chicken heart/liver/gizzards, one whole soft boiled egg with the shell, fish oil, plain yogurts & a multi-vitamin pill for puppy (GNC brand). I keep him in my house in a crate when I'm at work and I let him out to play in the house when I'm home. I work 12 hour shift so when I leave for work it's still dark out and when I returned home it's dark already too. Due to my work schedule I understand that my pup don't get very much direct sun light especially now that it is winter and I live in MN. Does anyone know if his flat/splayed/outward paws is a genetic issue or is it something that I'm doing wrong? If it's something that I'm doing wrong can my pup's paws be fixed and have normal paws/wrists again?
