How to Know If Your Dog Has CDS and the Ways You and Your Veterinarian Can Help
Did you know that dogs are generally considered “seniors” at seven years of age? The adage that one dog year equals seven human years isn’t too far off. Some changes can be expected as a dog ages – osteoarthritis, dental disease, hearing loss – and your veterinarian is the best resource to navigate these changes to help make your dog’s senior years as happy and comfortable as possible.
However, there are some changes associated with aging that are part of a clinical syndrome known as “Cognitive Dysfunction Syndrome,” or CDS. CDS can affect both dogs and cats, but for the purpose of this article, we’ll be focusing on dogs.
If your dog has recently been diagnosed with CDS or you suspect it due to some recent behaviors, this article should help. Below, we’ve rounded up some information on:
- Some signs of Cognitive Dysfunction Syndrome in dogs
- What you can do at home to alleviate CDS symptoms
- How your veterinarian can help with CDS
Signs of Cognitive Dysfunction Syndrome in Dogs
Comparisons between CDS and Alzheimer’s disease in humans show that many of the changes at the cellular level in the brain are similar between the two, so you might have heard CDS referred to as “Dog Alzheimer’s.”
The signs of CDS can be summarized by the acronym “DISHAA”:
- DI – Disorientation
- S – Sleep/wake cycle disturbances
- H – House soiling
- A – Activity changes
- A – Anxiety
Many owners will notice changes as their dog ages that indicate CDS.
Some signs of CDS that are often noticed by dog owners are:
- Trouble sleeping
- Pacing (especially at night)
- Vocalizing inappropriately (howling or crying suddenly, especially at night)
- Staring off into space
- Getting stuck in corners or areas of the house that were previously navigated normally
- Having accidents in the house
These changes were previously thought of as “normal” age-related changes, but now we know that they indicate a disease process that can, in many cases, be addressed by your veterinarian.
What You Can Do to Lessen Symptoms of CDS in Dogs
When a dog is experiencing changes associated with CDS, you can make a variety of environmental changes to alleviate their symptoms.
Some things you can do to help your dog with CDS are:
- Keep a predictable routine to help lower anxiety
- Maintain furniture positioning in the house to reduce disorientation
- Encourage frequent trips outside or introduce soiling pads, which can decrease the frequency of accidents in the house
How Your Veterinarian Can Help Your Dog with Cognitive Dysfunction Syndrome
Feel free to ask us about dietary supplements and prescription diets that have been shown to reduce symptoms or slow the progression of CDS. Some medications have been shown to do the same that are explicitly targeted to CDS, and others are general anti-anxiety medications that can be added to help improve the quality of life of a dog in the early or late stages of cognitive dysfunction. Your veterinarian is the best resource to evaluate your pet for CDS and determine what treatment tools will benefit your pet and improve their quality of life.
Having a senior pet certainly comes with its share of challenges. The best way to navigate these is to have routine physical exams and diagnostic testing performed (especially after seven years of age). Metro Paws Animal Hospital offers a Senior Wellness Package for all pets receiving annual vaccines, which includes a broad bloodwork panel to evaluate internal organ function and full body X-rays to screen for problems that may appear on an X-ray before your pet is showing outward symptoms.
If you suspect your pet is experiencing symptoms of CDS, diagnostic testing will be recommended to rule out any other potential causes (such as metabolic diseases that cause increased urination, etc.) before treatments for CDS can be explored. Here is an excellent tool for evaluating your pet for possible cognitive dysfunction—free to bring this assessment to your veterinary appointment. Although CDS currently does not have a “treatment” or cure, there are many things you and your veterinarian can do to ensure your pet’s quality of life remains as high as possible well into their senior years.
