Canine cognitive dysfunction (CCD) is a condition in dogs that affects their mental abilities, including memory, learning, awareness, and problem-solving skills. It is often referred to as "doggie Alzheimer's" or "senility" in dogs. This condition typically occurs in older dogs and is similar to Alzheimer's disease in humans. Symptoms of CCD in dogs can include disorientation, confusion, changes in interaction with family and environment, alterations in sleep-wake cycles, and decreased responsiveness to training and commands. CCD can have a significant impact on a dog's quality of life and may affect its ability to perform daily activities. If you suspect your dog may be experiencing CCD, it is important to consult a veterinarian for a proper evaluation and to discuss treatment options, which may include medication, dietary changes, and environmental enrichment.
