A fully developed bog spavin is shown on the left leg in the right hand 

 illustration, while the one in the left illustration shows a large ringbone 

 at the base of the pastern. 



A clean, clearly defined hock appears in the photo on the right shown 

 from the point of view most likely to discover bone spavin. The photo to 

 the left shows this, as a spavin may be clearly seen at the inner base of the 

 right hock.
