Dog Dementia: Does Your Dog Have Canine Cognitive Dysfunction?

dog dementia

Just like you, your dog’s brain ages and wears out just like the rest of his body.

But in some dogs, the brain wears out quicker than in others. This causes a spectrum of symptoms that we call Canine Cognitive Dysfunction (CCD), or simply, dog dementia.

The degenerative changes in the brain tissue that cause dementia in dogs aren’t well understood. We do know that the number of nerve cells reduces as dogs age. A build-up of neurotoxic deposits in the brain may also be a contributing factor. High levels of free radicals also appear to lead to decline in cognitive function.  

So, how common is dog dementia and how do you know if your dog has it?

How Common Is Dementia In Dogs?

Canine cognitive dysfunction is more common than most dog owners realize! In one study, approximately 50% of dogs over 11 years of age displayed at least one sign of CCD. Another study showed that 68% of dogs between 15 and 16 years of age may show at least one sign of CCD.

Another important thing to note is that CCD is a progressive disease. More than half of the dogs with at least one clinical sign will develop more symptoms within 12 months.

The older your dog, the more likely he is to develop CCD. That said, giant breeds age more quickly and may develop CCD as early as 5 to 7 years old. Also, it seems that neutered dogs have a slightly higher risk.

Signs Of Dementia In Dogs

Dementia in dogs can be easy to miss for a
couple of reasons:

#1 Dementia is very slow to develop. The symptoms come on so slowly that they just seem to be part of the normal.

#2 There’s a myth that it’s normal for old dogs to get a bit strange. Many people write it off as a ‘normal’ part of the aging process (it isn’t).

So how can you tell if your dog has dementia? We’ll use the acronym “DISHA” to look at the common symptoms of dementia in dogs.

1. Disorientation

This can include staring into space or getting lost in familiar surroundings. This can include not being able to find his way in and out of the house, getting stuck in corners or under tables. Your old friend may seem confused all the time. Some dogs will forget you’ve fed them. You may also see anxiety develop with a range of triggers. He may start barking at nothing. Continual pacing is another common symptom.

2. Changes In Interactions

Your old dog’s ability to maintain healthy relationships may decline. He may either show decreased affection or become overly attached and stick to a particular person like glue. Some will become irritable and grumpy.

3. Sleep-wake Cycle Changes

This is where sundowner syndrome can kick in or sleep patterns will become affected. Your old friend may start to become unsettled in the evenings or all through the night. Some dogs with dementia won’t sleep at all and others will wake often, be restless, etc. They will often bark in the night for no clear reason. And sometimes they’ll sleep all day and be up all night, wanting your attention.

4. No Longer Housetrained

Your dog may forget all his housetraining and start messing in the house. This can also happen because he can’t find his way outside at all, or in time. You may also see a lack of response to commands and an inability to perform tasks that he once could do with ease.

5. Reduced Activity Levels

Your old friend may not want to do anything much at all (sometimes not even eat). On the flip side, you’re likely to see restless behavior with continual pacing or aimless wandering around. Some dogs will develop obsessive-compulsive behaviors like licking floors.

Act Early To Prevent Dementia In Dogs

Yes, dementia in dogs is a progressive, degenerative disease. It gets worse over time, BUT there’s plenty you can do to slow it down, and often reduce or sometimes even clear the symptoms altogether.

Keep an eagle eye out for any symptoms. If you see any subtle signs, it’s time to kick into overdrive and take action. I can’t stress enough that the prognosis is good if your dog’s dementia gets diagnosed early, and poorer if diagnosed late.

The sooner you act, the better the results will be.


To help delay the onset of dementia in dogs or prevent it altogether, you should feed a healthy, complete, whole food diet. Raw is usually best, but some older dogs do better on a home cooked diet if their digestive fires are burning low.

You’ll also want to consider adding some (or all) of the following supplements:

  • High-quality omegas-3s. (EPA and DHA play an important role in brain health).
  • Give plenty of vital antioxidants (these help lower toxic free radical levels in the body). One great antioxidant supplement is blueberries. Another is green tea steeped in cold water for 12 hours.
  • CBD oil is the best medicine I’ve ever seen for dementia in dogs. I had one dog who had kept his mum awake every night for a year sleep through the night after just 3 days on CBD. I have consistently seen obvious reductions in symptoms with the use of CBD Oil.
  • PEA (Palmitoylethanolamide) is another non-toxic, natural and highly effective medicine. You can use it alone or alongside CBD oil.
  • I have found that many dogs with dementia have significant undiagnosed pain (usually from arthritis or back pain). When treated with appropriate pain relief, the symptoms often improve significantly. Natural medicines such as turmeric (golden paste) and green-lipped mussels can make a big difference.

Other supplements that are of value include:

  • SAMe (S-Adenosylmethionine)
  • Ginkgo biloba
  • Melatonin
  • Vitamins C, and E
  • B Vitamins
  • Gotu kola
  • Resveratrol
  • Valerian root

Please note: if your old dog is nearing the end, palliative use of any and all prescription pain relief medications that help may be necessary.

Other Ways To Help Prevent Dog Dementia

Hands-on bodywork can be a huge help with increasing quality of life by reducing anxiety and pain while increasing connection. Acupuncture or acupressure with Traditional Chinese herbs can be a great support for dogs with dementia.

When caring for a dog with dementia, there are also a host of proprietary remedies out there in the wild. I encourage you to seek a holistic vet or a skilled animal naturopath. They can help make sure that you give your old friend the best treatments for his needs.

And last, but definitely not least, is enrichment and gentle exercise and affection. Do things with your old dog: simple games, gentle training sessions, intentional touch and regular light exercise. This will help give him mental stimulation.

Be sure to keep the house uncluttered and all the furniture in the same place. And enjoy every moment, with heaps of love, tons of cuddles and a heart full of compassion!
