How to treat arthritis in rottweilers
Watch your rottweiler move around.
With arthritis, your rottweiler's joints start to break down and become inflamed. The subsequent pain and discomfort will likely keep him from being able to move around like he used to.
For example, if he used to run and greet you at the door, he may now walk slowly towards the door or just stay where he is. If he used to walk up and down the stairs easily, arthritis may make him more cautious about using the stairs.
