Oh he looks JUST like my Nala with her wonky leg. Unfortunately thatís not a knuckling situation and correctable only through surgery. Itís an Angular Limb Deformity (ALD) likely caused because one leg stopped growing before the other. The best thing you can do is keep your dogs weight down, try to lessen the impact on the front legs as much as you can (try to limit jumping down as much as you can) and supplement - I give Dasaquin but glucosamine supplement will help.
Hope that helps!
