Arnie the homeless dog needs to be examined to make a diagnosis

In December, the dog appeared from nowhere at an enterprise near Moscow. At first, everyone thought that he got lost while hunting, but the search for the owners did not bring results. The guardian noticed that the dog was walking strangely and dragging his ass. Arnie was taken to the clinic. The X-ray showed the destruction of the elbow joints of the forelegs and fusion of the vertebrae. To make an accurate diagnosis and prescribe treatment, you need to do an MRI scan of the spine.
