We remember the times we shared and are often saddened by the changes we see. As our companions age, they undergo both physical and metabolic changes that affect our interaction with them. These physical and metabolic changes can often manifest themselves as behavioral changes. The aging dog undergoes many physical changes as time passes. Within the Musculoskeletal system these changes can be profound.
Many older dogs develop arthritis in their joints and spondyliti changes the spine.
Geriatric dogs also show a decrease in muscle mass. These changes may be accompanied by outward physical manifestations that the owner can see. When arthritis is present, the animal may limp or hold up the affected limb, or the joint may be painful to movement or touch. In the case of spondylitis, the animal may be unwilling or unable to go up and down stairs, jump on furniture, or even sit comfortably. These changes in mobility can then affect the dog's behavior.
