If his foot is turning outward, please consider taking him to see an orthopedic vet - one whohas had some experience wiht bassets. It could - and i say *could*, mostly because I find it hard to belive that a basset fed a high-quality food could have rickets - be something more serious, like ununited ancoineal process. This is when one of the two bones in the lower forleg stops growing too soon. This causes the other bone to curve inward, bowing the leg, displacing the joint, and often causing the foot to turn outward. It can be very painful for the dog, and is sometimes seen in bassets. It most commonly first appears between 12-24 weeks of age, but can occur later.
