Dogs get aggressive with age primarily due to underlying medical issues like pain (arthritis, dental), sensory loss (vision/hearing), or cognitive decline (dementia), which makes them fearful, irritable, and less tolerant, causing them to snap or bite when approached or startled, as they can't cope as well. A vet visit is crucial to rule out physical problems, but also to check for mental changes like Canine Cognitive Dysfunction (CCD), similar to Alzheimer's, which impairs memory and awareness, leading to confusion and aggression.
