A. Problems with walking in the front legs can be caused by a large number of things. Arthritis in older dogs can cause joint pain and stiffness which may make walking hard. Nerve or muscular damage may also cause problems.
With nerve or muscle damage there is often a loss of muscle tone in the affected limbs. Limbs may look skinnier than unaffected ones, and may lose overall muscle mass. In some cases, treatment for pain or soreness may help improve symptoms some. Depending on the severity of the damage, some dogs may recover while others have permanent damage.
It may also be that if your dog was putting all his weight on one front leg to help the other, that the good front leg is now stiff and sore. Restricting exercise, giving a supplement to help joints and bones and following your veterinarian's recommendations for care can all help your dog to feel a little better.
