Aging dogs experience various structural and functional changes in their brains. These changes can include the shrinkage of brain tissue, especially in the cerebral cortex and hippocampus, which are responsible for memory and learning.
Dogs, like humans, can experience cognitive decline with age, impacting their memory and problem-solving abilities. This condition, known as canine cognitive dysfunction, shares similarities with Alzheimer's disease in humans.
Reduced sensory perception
Aging in dogs can result in reduced sensory perception, affecting their hearing, vision, and sense of smell. This decline can impact their ability to navigate and engage with their surroundings.
Changes in sleep patterns
Older dogs may exhibit altered sleep patterns, sleeping more during the day and experiencing disrupted sleep at night, likely due to changes in brain chemistry and hormones.
As decreased activity, reduced interest in play or exercise, and increased irritability or anxiety. These changes can be linked to the natural aging of the brain and the potential development of age-related conditions.
Dogs face an increased risk of neurodegenerative diseases like canine cognitive dysfunction, Parkinson's-like conditions, and dementia. These conditions can worsen cognitive decline and present other neurological symptoms.
