How to diagnose arthritis in rottweilers
Take notice of any limping.
Most signs of arthritis are related to mobility. Often one particular joint is affected more than the others, and this can lead to your dog limping or standing with less weight on the sore leg than his other legs.
However, in the early stages, your dog can often run freely and forget about the discomfort when he sees something to chase after. Therefore, it can appear that the lameness comes and goes and is worse before a walk than during the walk.
