As I sit here at home writing this blog, the tears are running down my face. My beloved old girl Zoe, is currently navigating the painful reality of Parkinson's Dementia , and it's a journey that has deeply impacted my heart. Watching her-once full of life and spark-now struggle with the confusion and forgetfulness that comes with cognitive decline has made the reality of Dog Dementia, or Canine Cognitive Dysfunction (CCD), feel all too real. In this blog, i'll share the signs, and symptoms of dog dementia, how to manage it, and the lifestyle changes that can improve your dog's quality of life. Unfortunately, it also brings the heartbreaking decision of knowing when it's time to say goodbye. Through Zoe's journey, I hope to shed light on this difficult experience and offer comfort to those facing the same challenegs with their furry companions. You're not alone in this.
So what is Canine Cognitive Dysfunction (CCD)- Doggie Dementia?
Canine Cognitive Dysfunction (CCD), if often referred to as dog dementia, is a condition in older dogs that causes a decline in brain function, similar to dementia or Alzheimer's disease in humans. It is a progressive, age-related disorder that affects a dog's memory, learning, perception and their behaviour.
Dogs with CCD may exhibit symptoms such as:
Confusion
Disorientation
Disrupted sleep patterns
House soiling
Increased anxiety
Changes in their interactions with their owners and environment
Depression
Slowed movement
Rigid Muscles (stiff, inflexible muscles)
Loss of smell
Swallowing problems
Tremors in one or more legs
Fidgeting or restlessness
In Zoe's case, her changes are reflective of how CCD can manifest in a dog's daily routine and interactions. My girl Zoe now exhibts anxiety in certain situations, that once would have never phased her, a behaviour that is uncharactertistic for her. Zoe now experiences restlessness, especially at night, with broken sleep patterns and pacing around the house. This disruption to her nighttime routine can be a sign of disorientation or discomfort, both of which are common in dogs with cognitive decline. In addition, Zoe's previous close bond with Shadow, a relationship that was her anchor after my beautiful soul dog Chase passed (10 years) seems strained. She has become grumpy and more easily irritable, even with people she has loved and trusted for years. This can often be attributed to the confusion or frustration dogs feel when they struggle to process the world around them.
Another key sign of CCD in Zoe is her eating habits, sometimes forgetting she has eaten. Her once enthusiastic enjoyment of scrambled eggs on Sunday mornings, a cherished ritual, has become a thing of the past. She struggles to eat it, and now once she has finished eating her dinner she immediately rushes to the toilet, This could be a sign of disrupted digestion or an inability to process food in the same way, both of which are frequently seen in older dogs with cognitive dysfunction.
Additionally, Zoe has a tendency to walk into a room and forget what she is doing, another classic symptom of CCD. This kind of disorientation is heartbreaking, as it reflects a gradual loss of memory and the ability to follow familiar routines.
Despite the challenges Zoe faces with Canine Cognitive Dysfunction, there are still moments of joy and familiar pleasures that continue to light up her days. Zoe’s love for the beach remains unwavering. There’s a sparkle in her eyes when she gets near the water, and even though she may be slower now, she still loves to take a swim, letting the cool waves wash over her as she wades in, or rolling around in the sand, just like she used to. These simple pleasures seem to ground her, offering a sense of peace in the midst of her confusion. Another of Zoe’s enduring favorites is sardines—she still devours them with the same enthusiasm as always, reminding us that some tastes never lose their appeal.
Her daily walks may be slower, but Zoe still enjoys her quiet strolls down the street to the park, where she takes her time sniffing the air and exploring the familiar scents around her. It’s as if she’s savoring each moment, even if the pace is gentler now. Treats are another highlight of Zoe’s day; she may move with more caution, but the moment she hears the crinkle of a treat bag, she’s right there, tail wagging in anticipation. One of her favorite pastimes, especially on warmer days, is playing under the hose. The cool spray on her coat and the fun of trying to catch the water stream still bring out her playful side. And, of course, the simple act of getting pats—gentle strokes and attention—always makes Zoe feel safe and loved, even if she sometimes seems a little distant. These cherished moments, though sometimes fleeting, remind us that her heart is still the same, full of love for the things that have always made her happiest.
When managing a dog like Zoe with Canine Cognitive Dysfunction, it’s crucial to make several lifestyle changes to help support her cognitive health and overall well-being. One of the most important dietary changes is to add more omega-3 fatty acids, particularly DHA and EPA, to her meals. These essential nutrients have been shown to support brain function and slow cognitive decline in dogs. Omega-3s not only help maintain cognitive function but also provide benefits for joint health, which is important as Zoe’s activity levels decrease with age. You can incorporate omega-rich foods like fish oil, sardines, or flaxseed into her diet, or consult your vet for high-quality supplements designed for senior dogs. Ensuring that her diet is rich in antioxidants, vitamins, and other brain-supporting nutrients can further enhance cognitive health and overall vitality.
In addition to dietary adjustments, lifestyle changes that offer both physical and mental comfort are essential. Dogs with CCD, like Zoe, can often become disoriented or anxious, so providing a calm, structured environment can help reduce confusion. When Zoe seems lost or agitated, it’s important to gently comfort her and, when possible, redirect her attention to something familiar and soothing. This might involve guiding her to a favorite spot, offering a comforting object, or engaging her in a low-stress activity, like a leisurely walk or a light play session. Keeping her routine as consistent as possible—such as regular feeding times, walks, and quiet play—can also reduce anxiety. Additionally, providing cognitive enrichment through simple puzzles, scent work, or gentle training sessions can help keep her mind active and engaged. Offering a comfortable, supportive bed, especially one designed for senior dogs, can help with any joint pain, ensuring she gets the rest she needs without discomfort. As Zoe’s needs change, being patient and attentive while adjusting her routine can help her feel secure and cared for during this challenging time.
Regular vet visits are absolutely essential when managing the health and well-being of an older dog like Zoe, especially when dealing with conditions like Canine Cognitive Dysfunction. Zoe had her check-up this week, and it was reassuring to know that her heart is still in great condition, and despite some arthritis, she is doing well overall. Her vaccinations were up to date, and she received arthritis injections to help ease any discomfort she might be feeling. What stood out most during the visit was how attentive and compassionate the vet was in listening to all of my concerns about Zoe’s changes in behavior and her declining mental health. I may be an "over-the-top dog mum," but having a vet who listens carefully, takes your concerns seriously, and acknowledges the steps you've already taken to support your dog’s health is incredibly valuable. It helps you feel like a team working toward the same goal—ensuring Zoe’s quality of life remains as good as possible.
During the visit, we discussed some potential trial treatments and medication options to help with Zoe's anxiety and disrupted sleep patterns. The vet suggested some medications that might provide her with extra comfort during particularly tough moments. It was also reassuring to hear the vet say that, despite her age and arthritis, Zoe "looks amazing," a reminder of how well she's been cared for over the years. Having that positive feedback, coupled with actionable advice, gave me renewed confidence in the steps I’m taking to support her. Knowing that her medical team is both thorough and empathetic makes a world of difference in managing her cognitive dysfunction, and it’s a reminder of how important it is to keep the lines of communication open with your vet, especially during these later years.
Knowing when it’s time to put your dog to sleep is one of the hardest decisions any pet owner will ever face. It’s not just about whether your dog is in physical pain, but whether they still have a quality of life, and whether they’re still able to enjoy even the smallest joys they once did. It’s an incredibly personal choice, and sometimes it involves weighing whether to help your dog peacefully pass at home, surrounded by their family, or at the vet’s office, where they can be more comfortably cared for in a clinical setting. Both choices carry emotional weight, and no decision feels "right." The grief that follows is indescribable, an ache that doesn’t just fade with time. People who haven’t experienced it may brush it off by saying, “It’s just a dog, get over it,” but those words couldn’t be further from the truth. Studies (The Human-Animal Bond and Pet Loss" - Journal of Social and Personal Relationships (2011)) have shown that the loss of a pet can sometimes hurt even more than the loss of a human, likely because animals offer a kind of love that’s pure and unconditional, a love that’s often unwavering and entirely dependent on you. The bond with a pet like Zoe is unique—uncomplicated, unwavering, and rooted in mutual trust. So when they’re gone, it feels like you've lost a piece of your heart. The grief isn’t just about saying goodbye to a pet; it’s the loss of a friend, a companion, and a source of unspoken love, and it’s a pain that can’t easily be understood unless you've been there.
Canine Cognitive Dysfunction is a heartbreaking reality for many aging dogs, and watching Zoe navigate the challenges it brings is a constant reminder of how fleeting our time with them truly is. We are monitoring her closely, doing everything we can to ensure she feels comfortable and loved, while cherishing every moment we have left with her. It’s difficult, though, knowing that the day will come when I will have to say goodbye. The anxiety, panic, and tears that come every time I think about it are overwhelming, and the thought of that moment is crippling. Unfortunately, our dogs don’t stay with us forever, but we must make the most of the time we have, filling their days with love, joy, and peace. When the time does come for Zoe, I will find comfort in knowing she’ll be reunited with Chase, the love of our life, and together they’ll be running along the beach, just like they used to. They’ll be watching over us, and the bond they shared will live on in our hearts. Until then, I’ll continue to hold Zoe close, savouring every wag, every paw on the sand, and every precious moment we still get to share.

Reference: Melson, G. (2011). "The Human-Animal Bond and Pet Loss." Journal of Social and Personal Relationships, 28(5), 671-688.
Key Findings: This study suggests that pets play a unique and irreplaceable role in the emotional lives of their owners. The bond between humans and pets is often deeper than with some human relationships, primarily because pets provide unconditional love, emotional support, and companionship without judgment. The emotional distress of losing a pet can therefore be profound, and in some cases, pet loss is experienced as more intense than the loss of a human. The emotional pain stems from the lack of societal recognition for the grief of losing a pet, which can make the experience even harder to cope with.https://www.vet.cornell.edu/departments-centers-and-institutes/riney-canine-health-center/canine-health-information/cognitive-dysfunction-syndrome
