Because of loss of muscle mass, the older dog may need a softer place to lay down and may no longer be able to lay on a hard floor. This too needs to be considered so that the dog can join in with the family. These musculoskeletal changes can make it difficult for older dogs to walk on smooth or slippery surfaces such as wood, tile, or linoleum floors. Non skid area rugs strategically placed may enable the dog to navigate the home. Changes in the animal's joints can often be accompanied by pain.
Some dogs show very little evidence of pain, while others become irritable.
In consultation with a veterinarian, medications can be given to decrease pain and therefore increase the dog's ability to interact with people. Accommodations in sleeping arrangements and walking surfaces need to be considered to maximize the dog's comfort and minimize pain. Decreased mobility also affects how the pet may react to stressful events. Previously, the dog may have moved away from such a situation, but in its present condition, a lack of mobility or an unwillingness to move may require the dog to stay. This can result in a fearful situation for the dog that leads to aggression.
