This news item is about: Large-breed dogs like Labradors, Newfoundlands and Rottweilers can suffer from a forelimb lameness when they are puppies, which may result in a significant lameness later in life. One of the more common causes of this disability is a bone problem within the elbow joint called fragmented coronoid process, or FCP. The condition is a result of the ulna (one of the three bones that makes up the elbow) growing faster than the bones next to it, creating extra pressure in the elbow joint and causing the ulna to chip.
