Dogs age faster than humans and may spend a significant portion of their lives in a geriatric state. Recognizing the welfare needs of senior dogs and providing appropriate care is one of the most important responsibilities of dog ownership.
Senior dogs are often invisible in welfare discussions focused on shelter animals and factory farming, but the welfare of elderly companion animals in homes represents an important and personal dimension of animal care. Undertreated pain from osteoarthritis is the single most common welfare failure in elderly dogs — owners frequently attribute reduced activity to "slowing down with age" rather than recognizing it as chronic pain. Canine cognitive dysfunction causes genuine distress including nighttime waking, disorientation, anxiety, and loss of learned behaviors. Both conditions are treatable to meaningful degrees. Providing attentive, medically informed care to a senior dog is a significant welfare commitment — and for many people, among the most intimate acts of care for another being they will ever undertake.
