Ca/phos normal. Dog is of a decent weight too. Rads are stuck on a comp currently.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/83319?ContentTypeID=1Thu, 14 Feb 2013 14:13:35 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:3da36c39-3820-4cac-8237-4d2dd051596dNicola Lawlor<p>How strange. Hopefully someone with something useful will be able to help advise. It looks to me like the dog is abnormal with his hind limb stance too - he seems to have his hocks very low in some of the video with a plantigrade stance, though he does seem to be on the paw at other times. Perhaps this dog has some sort of collagen issue?? The whole R fore looks really wrong in how the dog holds it and places it. Is the leg deformed to look at when the dog is at rest as again to me in the video it seems that way. What about rickets?? Have you run Ca/Phos levels? Maybe you could post the xrays too for the orthopods here to take a look at?</p><div style="clear:both;"></div>
