don't know if this would help. although it about a gsd, it has somewhat simler problems,

But in my opinion if the problem isnt sorted now while the pup is young,
its going to have problems later in life, it could end up putting stress on the other toes,
and joints.
thanks chook...i`ve had a look, doesnt help me much , but i will look into that ester c . hes been on dried puppy food and raw minced chicken meat and bones since we brought him home....hes growing well and has great structure for a pup....its just them
