Dog dementia presents with a wide range of symptoms ranging from mild to severe. These symptoms are progressive and worsen over time. The most common symptoms of dementia in dogs include the following:

  • Confusion and disorientation (particularly in a familiar setting);
  • Failure to remember the training, house rules, and even routines;
  • No longer responding to their name or commands they previously learned;
  • Zoning out or staring blankly – at walls or even at nothing in particular;
  • Aimless wandering;
  • Irritability;
  • Anxiety;
  • Loss of interest in play;
  • Decrease in grooming;
  • Loss of appetite;
  • Changes in sleep patterns.

Diagnosing dog dementia

When you spot the signs that your dog is beginning to behave a little strangely, head to the vet for further investigation. Various other conditions can cause similar symptoms to dementia in dogs, so it's best to let your vet investigate to make sure. Conditions that can be mistaken for dog dementia include, but are not limited to:

Your vet will use the acronym DISHA to make a formal diagnosis and will ask you various questions about your dog's behavior:


This is the most noticeable sign of dog dementia. Disorientation includes behaviors like wandering around, seeming lost in a familiar setting, as well as zoning out or staring into space, at walls, at the floor, and at nothing in particular. Other behaviors include failing to recognize people they know and having trouble moving around objects like coffee tables, lamps, etc.

Interaction changes

Include things like your dog no longer wanting to be petted and spending more time away from the family. Dogs may appear much less into being social with humans or other animals, or they may become extremely clingy and anxious at being separated from their humans.

Sleep/wake cycle disruptions

Your dog may begin to display changes in his sleep/wake cycle. This leads to a situation where your dog cannot sleep through the night and so will end up walking around the house, barking, and even whining while the family is trying to sleep. As they're awake at night, your dog may sleep more during the day.

House soiling, memory, and learning

Well-house-trained dogs will often begin to have accidents in the house. They don't alert you to the fact that they need to go and then go in various areas throughout the house. Commands or tricks your dog used to respond to no longer elicit any reaction from your dog; in fact, it seems harder and harder to get your dog's attention.

Activity changes

Your once active and energetic pup is now less interested in exploring or reacting to the usual things that would excite them. Things like other dogs, birds, people, and neighborhood noises that used to get a reaction, now no longer appear interesting at all. Things like grooming become less frequent, appetite decreases, and your pet may seem a little restless.

Treatment and prevention

Sadly, there is no cure for dog dementia, but there are several treatment options to consider in managing the condition. These may include medication, diet changes, supplements, and even surgery in some cases. The sooner you begin these, the better the prognosis.

They say prevention is always better than cure, so what can you do to prevent canine cognitive dysfunction in your beloved dog?

As there's no clear cause for dementia in dogs, it's hard to know how to prevent dog dementia. But, maintaining a physically and mentally active life may help to prevent dementia in dogs. Aim to include things like:

  • Keep teaching new tricks;
  • Playtime is essential, as is regular exercise;
  • Maintain a balanced diet;
  • Choose supplements for brain health;
  • Regular socialization and new experiences.
  • Install the interactive pet camera to watch what your pup is doing over the day.
