Yes. We are all aging - our dogs too. For our beloved geriatric pups aging can present as dog dementia. In dogs, dementia is usually referred to as cognitive dysfunction syndrome or cognitive dementia. Canine cognitive dysfunction is when aging dogs suffer from mental and behavioral decline associated with changes in their brains. This condition is quite similar, but is not exactly the same, as that in Alzheimer’s disease in humans. In humans, the damage in Alzheimer’s disease is permanent and irreparable.
In dogs, however, the outlook is more positive because behavioral signs of dementia are temporarily reversible and the progress of the disease can be slowed down.
Cognitive dysfunction results from changes in the brain associated with aging such as decline in neurons, decrease in cerebrovascular blood flow, or increase of neurotoin deposits. This result in the dog’s decreased responsiveness to stimuli, and decreased ability to learn and remember.
