As dogs live longer due to improved veterinary care and nutrition, the welfare needs of senior and geriatric dogs are receiving more attention. Understanding how aging affects dogs helps owners provide the best quality of life in their final years.
Senior dogs face welfare challenges on multiple fronts. Chronic pain from arthritis, dental disease, or cancer is among the most common and most undertreated sources of suffering. The normalization of reduced activity in older dogs means that pain-related behavioral changes are frequently attributed to 'slowing down' rather than recognized as treatable suffering. Cognitive dysfunction in elderly dogs causes confusion, altered sleep-wake cycles, anxiety, and loss of previously learned behaviors - distressing for the dog and often misunderstood by owners. The welfare of end-of-life decision-making is critical: recognizing when quality of life has declined below a reasonable threshold and providing a peaceful, pain-free death through euthanasia is one of the most important welfare decisions owners make.
