Just like us, dogs go through many changes as they age. There will be a graying around the muzzle, they may need more sleep, the step is not as quick as it used to be. With some dogs, you may also see significant behavioral changes. Canine Cognitive Dysfunction Syndrome (CDS) is caused by physical and chemical changes that affect brain function in older dogs. Although not identical, pathological changes in the brains of dogs with CDS are similar to those seen in human Alzheimer patients.
Dogs with CDS may show behavioral changes such as confusion and forgetfulness, and may be less responsive to their owners. Advances in veterinary medicine have made it possible for our companion animals to be with us longer, which is a wonderful thing. However, these advances have increased the population of geriatric pets, resulting in more dogs with CDS, and requiring us pet parents to become more knowledgeable about the syndrome.
The classic signs of CDS in old dogs include:
· Reduced activity
· Changes in sleeping patterns
· Reduced responsiveness to people
· Lack of interest in surroundings
· Confusion, disorientation
· Pacing, wandering
· Inability to recognize familiar people
· Increased thirst
· Excessive panting
· Difficulty eating or reduced interest in food
· Loss of bladder and bowel control
· Difficulty navigating their environment
There are a few things that may help dogs with CDS. Studies have shown an improvement in most dogs within one month of starting to receive L-Deprenyl (Anipryl). CDS is often associated with the depletion of dopamine, and this drug works by helping to prolong dopamine activity and by reducing the amounts of free radicals in the brain. Dietary changes may also help to alleviate CDS. Therapeutic diets containing antioxidants, mitochondrial cofactors, and omega-3 fatty acids are recommended.
Environmental stimulation in conjunction with dietary change, is good for elderly canines. You CAN teach an old dog new tricks, and you should, to keep your dog’s mind working. We’ve all experienced or heard stories about older dogs becoming more lively with the introduction of a puppy into the household. Use caution with that because a very old dog might not adjust well to such a dramatic change.
Finally, the best things we can give our old dogs are love and understanding. Learning about CDS will help us to understand why our old dog has changed. And, love will help everyone to get through a difficult period in our friend’s life.
