The author is a proud parent of a Boston Terrier. She enjoys sharing her knowledge on various researched topics on the canine world.
My Boston Terrier has always been a happy-go-lucky dog with a busy disposition. However, things have changed since she’s entered her senior years. At age ten, she no longer likes to play roughhouse, nor can she jump on the bed without tumbling to the floor. It’s not uncommon: Both scenarios are quite typical and a natural state for aging dogs.
For pet owners who might witness this gradual physical shift in a dog’s life, it’s normal to feel a sense of foreboding as one considers the inevitable heartbreak of losing a pet to old age.
What’s even more disconcerting are the strange and disturbing behaviors that my dog has shown in the last few months. These inexplicable changes prompted me to do an online search and set up a visit to the veterinary clinic for a geriatric condition known as Sundowners Syndrome in dogs.
If you’re like me, concerned and want to know whether your dog has this type of health issue, then let’s go over this debilitating condition.
What Is Sundowners Syndrome in Dogs?
In simplified terms, Sundowners Syndrome (also known as Canine Cognitive Dysfunction) is a common degenerative and progressive dementia experienced by aging dogs that impairs a pup’s awareness and responsiveness to their once normal setting.
According to Dr. Becky Lundgren, a schooled veterinarian and partner for Veterinarian Information Network—in her research article Senility in Dogs—a recent study reveals that out of 69 dogs, 32% averaging the 11-year mark had Sundowners whereas 100% at 16 years or older suffered from this deteriorating condition.
Given these statistics, it’s no wonder why so many pet owners overlook the earliest stages of cognitive dysfunction, mistaking the disorder's subtle signs for a natural aging process.
So how do you determine if your dog suffers from canine senility?
There are quite a few key behavioral changes that can help you determine whether your dog has reached this point. Perhaps the most noticeable change by far is the disruptive onset of nighttime anxiety. Let’s look at the following table compiled with several common signs and symptoms.
Common Symptoms of Canine Sundowners
Excessive or Excited Barking
Aimless and Incessant Wandering
Unable to Process Tricky Situations (Getting Stuck)
Disorientation & Malaise
Blank Stare (Fixated at Wall or Floor)
Nighttime Anxiety and Panting
Disruption of Sleep Cycle
Lack of Response to Trained Commands
Increased House Soiling
Pacing in Circles
Difficulty Recognizing Family Members
Sundowners a Slow Degenerative Condition
Sundowners develops over time, yet remains progressive and persistent. Even though the cause behind cognitive dysfunction (changes in the brain) remains unsolved in dogs, some researchers relate the condition to several plausible scenarios such as doggie fatigue, changes in hormone levels, visual impairments, or the biological clock going awry.

According to research attained by the Lap of Love Veterinary Hospice, as noted in their educational pet disease series, 50% of dogs over age 10 will exhibit one or more symptoms of the syndrome. As the symptoms increase and the dog advances in senility, their behavior can compare with humans suffering from the neurological and physiological complications of both Alzheimers and Parkinson's.
Old dogs, like old shoes, are comfortable. They might be a little out of shape and a little worn around the edges, but they fit well.

Management of Sundowners
Any pet owner dealing with the stress of managing a senior dog with cognitive issues may have to alter their lifestyle to help ease the severity of the said condition.
- If possible, walking your dog three times a day eases restlessness in the evening hours.
- Set up a slumber routine that allows for a full night’s rest without a potty break (earlier meals and watering hours)
- Most dogs crave the comfort of human contact. Incorporating a daily massage toward the evening, readies your dog for sleep and allows them to relax in a more blissful state.
- Ensure your pet has a warm sleeping location to help regulate body temperature.
- Opt for orthopedic bedding such as the type my pet uses. Erognomic beds help reduce muscle aches and joint pains, and promote a better rest for your senior dog.
- Playing peaceful music may help soothe anxiety and lessen restlessness.
- If your dog suffers from visual impairment, installing a nightlight might be another option to help reduce anxiety because of confusion.
Possible Treatment Options
Note: If you suspect your pet has Sundowners, the very first thing to do is schedule a visit to your local veterinarian. Do not start any of the below meds or diet changes beforehand.
According to Camille Schake, the founder of the Good Pet Parent Blog, an author, and former Registered Veterinary Technician who wrote an informative piece Sundowner Syndrome in Dogs, she explains there are a few treatments that your vet may suggest:
- Prescription of Selegiline, a medicine that triggers higher dopamine levels in the brain and reverses changes caused by canine cognitive dysfunction.
- Anti-anxiety medications to help lessen the more severe symptoms associated with the dysfunction.
- Dietary changes or supplements that increase the amount of Omega-3 fatty acids and antioxidants your dog consumes.
- Melatonin, a supplement that balances hormone levels and can help regulate sleep irregular patterns.
My Personal Story
If you’re a senior dog owner looking for answers and dealing with this disorder just like me, then I’m certain you’re ready to do anything you can to help your pet.
First, know that you cannot fix the problem on your own. However, there is hope.
First thing’s first, make an immediate appointment to see your local vet. I cannot say it enough. Note that there is no cure for the syndrome, but your vet can help you with proper medications and supplements, and a better healthcare regimen. Do not wait. Your dog needs the love and care it deserves. You and your family deserve a break! I know. After endless nights, trying to care for my pooch without the proper sleep, the amount of anxiety and stress had taken a toll on my morale. I had no choice but to see my vet. Since then, my senior dog has made excellent progress and there’s less all-around anxiety and stress in our home.
