![At the end of a few steps, however, the fore paw of the operated side doubles up under the body and the animal falls on this side. In all these movements the fore paw of the injured side appears feebler and less mobile than that of the healthy side. At rest during abdominal decubitus it is nearly always in supination. ]Many more days are necessary before the animal can pass from this imperfect position to a position on its four paws; before it succeeds there are numerous attempts. The front legs always being in abduction, the posterior portion of the body is at first only half sustained, and more on the healthy side than on the operated side, where the rump is nearer the ground. As soon as a fore paw is lifted, the body falls down. Little by little, the Fig. 41. The same dog at the moment of a fall, the left fore paw being put suddenly in adduction. (After a photograph.) posterior half of the body is lifted higher above the ground, but for a long time, for several weeks even, it is upon an inferior plane to the anterior half of the body. Fifteen days after the operation, equilibrium can be main- tained on the four paws for a short time, after which the tremor and oscillations of the trunk, either antero-posterior or transverse, reappear and entail a fall. The fall is still inevitable if one paw leaves the ground. Fatigue rapidly supervenes. During the posi- tion on the four paws it is not uncommon that the front legs separate as if the paws slipped on the ground. It is from this moment that the animal makes serious efforts to walk. The anterior paws are wider apart than in normal standing. The one of the operated side is the more in abduction, and is usually the first to be lifted.
