Science is learning more about the aging process for humans and companion animals.With advances in veterinary care and knowledge of the importance of nutrition, dogs are living longer and, therefore, are experiencing more age-related issues, some that are even similar to humans.Forms of dementia are occurring with various symptoms in canines, previously called Canine Cognitive Disorder (CCD) but now named Cognitive Dysfunction Syndrome (CDS).Behavioral issues can result from CDS.As animals age, the body gradually loses its ability to regenerate cells and develops a slower metabolic rate.So we see loss of muscle mass, decreases in renal functionality, decline in cardiac efficiency, decreased oxygen in the blood, and degradation of the senses of sight, smell, taste and hearing.Studies also show that age-related changes may have a nutritional component. One theory proposes that as free radicals accumulate in the body, immune system responsiveness declines.
What are the symptoms of CDS?One of the first signs may be incontinence.When a dog who rarely has accidents in the house begins to eliminate in the house more frequently, it can be either a health-related problem, or possibly that he is forgetting where he needs to go. Another typical symptom is disorientation.The dog may get ‘stuck’ in the corner of a room, cannot find the door to come in from outside, does not recognize his family, wakes up in the middle of the night and paces or performs other repetitive behaviors such as licking and barking, and does not respond to his name or other commands.A dog who previously greeted his family at the door when they came home and now does not also can be a sign of trouble. Finally, older pets may begin to exhibit signs of separation anxiety.They may whine and bark or eliminate in the house when left alone.
What can you do?First, consult your veterinarian to ensure the issues are not related to an illness.Your veterinarian may prescribe medications to help the symptoms.Other things you can do to cope are:
1. Provide your dog with a diet high in antioxidants and omega-3 fatty acids.
2. Play games and teach your dog new tricks.Like humans, the brain stays healthy if it is exercised.
3. Maintain a consistent routine, ensuring you aren’t changing the dog’s schedule too much.Changes can cause confusion.
