Human cognitive abilities slow down as we age, and the same happens to dog brains. Here's a look at dog dementia and some natural remedies that can help your older dog ...
What Is Dog Dementia?
The medical term for dog dementia is canine cognitive dysfunction - or CCD. It’s a condition that mostly affects older dogs, and it’s similar to Alzheimer’s in people. Here's how to recognize symptoms and use natural remedies for dog dementia, to keep your dog’s brain healthy as long as possible.
Symptoms Of Dog Dementia
Research at University of Copenhagen found that 14% to 60% of dogs over 8 years old suffer from canine cognitive dysfunction (1). There are a few signs of CCD to look for if you’re worried your dog may be suffering from dog dementia.
Does your dog often seem confused about where she is? You may see her looking nervous and disoriented. She may have difficulty using stairs and doors, get lost in familiar places, or stuck in corners or behind furniture.
On its own, anxiety is not an indicator of CCD. Dogs can be anxious for a variety of reasons and may act out in different ways, including barking, whining, and chewing more than normal. But if your dog is often anxious and also has other symptoms listed here, she may have dog dementia.
Sleep Pattern Changes
You may notice changes in your dog’s normal sleep cycle. Not sleeping when she normally sleeps or sleeping for shorter periods could be a symptom of CCD. Sleeping during the day and restlessness during the night can be common in dogs with dementia.
Changes In Activity Level
It’s normal for dogs to be less active as they age. But if you notice a big change in your dog's energy level, keep an eye out for other symptoms as well. If your dog doesn't want to play or isn’t interested in going outside or on a walk, this can be a sign of CCD.
Accidents In The House
If your housetrained dog is starting to have accidents indoors, it may be a sign of CCD. She may have “forgotten” her training or just be confused about where she’s peeing or pooping.
Interacting Differently Than Usual
Dogs with CCD may become less social or change how they interact with you, other pets, and their environment.
So ... what causes dog dementia?
Causes Of Canine Cognitive Dysfunction
As dogs age, there are certain changes in the brain that lead to behaviors associated with CCD.
Oxidative stress is thought to play a big role in the degeneration of brain tissue. This happens when dangerous free radicals damage your dog’s cells. Free radicals develop as part of your dog’s normal metabolic processes, but if they’re uncontrolled, they can be harmful.
Lack of essential nutrients may also contribute to CCD. Your dog needs enough of certain vitamins including Vitamins A, C, D, and E as well as essential fatty acids to keep her brain membranes healthy.
Stress is another factor that can lead to cognitive decline. Chronic stress can affect your dog's hormones and immune system. That can lead to inflammation, and problems like digestive upset.
Finally, many holistic veterinarians believe that exposure to electromagnetic radiation (from wi-fi, cellphones, and other electronics) can impair cognition. This was evidenced by 2018 research in rats at Banaras Hindu University in India (2). So it’s a good idea to turn off wireless routers, cellphones, and other electronic devices whenever you’re not using them, especially at night or when you leave your dog alone in the house.
If you catch the symptoms of CCD early enough, you can intervene to slow you dog's decline.
Supplements For Canine Cognitive Dysfunction
Drugs prescribed for cognitive issues often come with side effects and need to be taken continuously or else the symptoms return. Before you resort to pharmaceuticals to help your dog’s cognitive issues, try a safer, natural approach.
1. Probiotics And Prebiotics
There's a relationship between the good bacteria in your dog's gut and her brain. It’s the reason the gut is called the second brain. As shown by research at several Mexican and US universities , there is an important substance called brain-derived neurotrophic factor (BDNF) that’s needed for cognitive functions (3, 4). Prebiotics and probiotics can help provide a healthy balance of friendly bacteria in the gut, which modulates inflammation and may activate the release of BDNF.
Feeding a raw whole food diet is the best option to ensure your dog gets all her ssential nutrients. Include antioxidant-rich foods to keep her brain safe from free radicals. Foods that specifically support brain health include …
- Blueberries: blueberries are high in antioxidants and 2011 research by Krikorian et al at University of Cincinnati found they improve memory in people (5). Another study by Miller et al, at Tufts University and University of New Mexico, showed that blueberries improved cognition in older adults (6).
- Lion’s Mane Mushroom (Hericium erinaceus). Lion's Mane mushrooms are neuroprotective, and can help brain cells grow and thrive. Several studies show that Lion’s Mane can prevent or slow cognitive decline, including 2015 research by US Department of Agriculture’s Western Regional Research Center that showed this mushroom improved anxiety, cognitive function, and depression (7, 8)
- Brain (organ meat): holistic vets recommend feeding your dog the organ she needs to support. Feeding fresh brain supplies your dog with the essential omega-3 fatty acids DHA and EPA that promote brain health.
- CBD Oil: CBD oil for canine cognitive dysfunction is often an excellent choicel. It can help regulate your dog's sleep-wake cycle and lower symptoms of anxiety and disorientation.
- Vitamin D may be particularly important in cognitive decline. Several studies, including a review at University of Exeter, show that low vitamin D levels are associated with dementia and Alzheimer’s (9). Consider adding a Vitamin D3 supplement to your dog’s diet.

There are many other natural supplements that may help your dog with cognitive issues, including omega-3 fatty acids, melatonin, and a supplement called palmitoylethanolamide (PEA).
3. Stimulate Your Dog’s Mind
Make sure to introduce your dog to new games, toys, and puzzles. Offering mental stimulation by keeping your dog curious, interested, and trying to figure new things out may help stimulate her cognitive abilities.
Research shows that CCD does not affect longevity. That's good news meaning that dog dementia isn't likely to shorten your dog's lifespan. However, it could reduce her quality of life... and yours. So, for both of your sakes, make sure you do your best to protect her brain health with some of these natural remedies for dog dementia.
