In addition to people having valgus deformity, dogs and cats can have this condition, also.
The neighbor down the street has a dog with this condition.The owner took him to a specialist, who said his problem was double bone growth in the joints. His paws pointed out and he would bite his paws.
Apparently, his case isn't too serious, but he could have surgery. The surgeon would take out some of the bone and then stabilize the rest of the bone. Luckily, he probably will not have any long term effects except arthritis in ten years or so. Lucky dog!
