Is your dog displaying behavioral changes? Is he or she failing to remember the regular routines? Does your dog appear to be confused or disoriented? If so, then your dog might be suffering from canine dementia. This is also referred to as dog dementia. In this blog post, I will be discussing what is dog dementia? How does it affect canines? What can you as a dog guardian do to prevent as well as care for your dog if he or she is suffering from dementia?

What is dog dementia?

Dog dementia is also referred to as canine cognitive dysfunction (CCD). Dog dementia is specifically a cognitive disorder that affects dogs. Dog dementia is basically an umbrella term that comprises of four different cognitive diseases which cause a decline in the brain function of the dog and wreaks havoc on the canine-human relationship. The four cognitive problems which come under the CCD spectrum are:

Involutive depression

You may not have heard this before but dogs also suffer from depression. There are several factors behind dog depression. However, the primary reason behind dog depression is the non-treatment of the anxiety faced by the dog. The symptoms of dog depression are wandering around the house, cycling or pooping at inappropriate places. These symptoms increase when the dog is kept in confinement or is feeling very anxious. Other symptoms of this form of dog dementia include sleeping disorders, decreased vocalizing as well as a reduction in learning capabilities and increased lethargy.

What is dog dementia?


Dysthemia is mainly observed in case of senior dogs. It often involves loss of awareness of the dog regarding his or her body length and size. Most dogs who suffer from dysthemia tend to get stuck in corners, behind furniture, or any other narrow regions where their body will not fit. To get out of such a situation all the dog has to do is to walk backwards. However, the dogs seem to be unable to comprehend this simple fact.

Other symptoms of dysthemia include excessive whining, increased aggressiveness, repeated growling behavior and finally it disrupts the sleep wake cycle of the dog. If you interrupt your dog while he or she is in the dysthymic state, there is a high chance that your dog may get angry and bite you. The primary reason behind this has been observed to be hyperadrenocorticism like Cushing’s disease as well as long-term therapy involving steroids.

Confusional syndrome

Confusional syndrome in dogs causes a reduction in the dog’s cognitive ability. This disease is the one with symptoms closest to Alzheimers disease in case of humans. In confusional syndrome, dogs do not learn well under any kind of training. They tend to forget the familiarity of their regular lives like other people and pets. When this disease goes into the advanced stages, dogs even start to forget who their guardians are.

Just like in the case of human dementia, the causes of confusional syndrome has not been properly deciphered. However, the accumulation of proteins called as beta amyloid plaques around the neurons as well as breakage of neurons resulting in neurofibrillary tangles has been implicated to be the major culprits. Just as it is observed in humans, these two phenomena work to interrupt the nerve impulse transmission in the brain causing the symptoms.

Hyper aggression

If you have a senior dog who suddenly starts to display aggressiveness for no reason, this behavior could most likely be associated with the dysfunction of structures related to the serotonin neurotransmitter in the dog’s brain. This may be caused due to the presence of cortical tumors is well. Dogs who have this form of CCD lose their capability to communicate with other dogs or animals. They do not give any kind of communication signal to the other animals or guardians nor do they understand the instructions given to them. Such dogs are likely to bite first and warn later.

What happens in the case of dog dementia?

Canine dementia causes aging of the dog’s brain. This leads to changes in the behavior of the dog as well as changes in regions that control comprehension capability, learning as well as memory. Clinical signs of dementia have been found in over 50% of the dog population beyond the age of 11 years.

The current advancements in veterinary medicine have improved the healthcare system for dogs which allows dogs to have a longer life. However, this also increases the incidence of dogs getting affected by CCD. Around 85% of the cases of canine dementia go undiagnosed and unnoticed.

In case you suspect that your dog is suffering from canine dementia, you should take your dog to your veterinarian immediately. Your vet will make a formal assessment and diagnose if your dog is suffering from CCD after he or she has ruled out any other medical cause behind your dog’s disorientation like

Symptoms of dog dementia

According to DISHA, the following symptoms are common in dogs who are suffering from dementia.


Disorientation is one of the primary signs that your dog is suffering from dementia. You may notice that your dog is wandering around the house like he or she is completely lost. The dog may seem confused about the surroundings and even forget the door which leads to the backyard or outside the house. Other signs of disorientation are that your dog may stare at walls, floor, or into the distance for no apparent reason. Your dog will have difficulty maneuvering around furniture and other objects in the house and may stop recognizing people, guardians or other animals in the house.

Interaction changes

If you notice abrupt changes in your dog’s behavior like not showing interest in the activities he or she loved to do on a daily basis, stops being social, and starts to withdraw, these are signs that your dog might be suffering from dog dementia. Your dog may become more clingy or may want nothing to do with you. It can be either of the two behaviors with extreme repetitiveness.

Disruptions of the sleep-wake cycle

This is possibly one of the most uncomfortable aspects of canine dementia. It causes changes to your dog’s sleep-wake cycle. Your dog may stop sleeping at night, roam around the house, bark at nothing, etc and sleep during the daytime. This destruction in the sleep-wake cycle is likely to cause your dog to feel heightened levels of emotions like fear, aggression or agitation.

Other common symptoms of dog dementia are:

However, the sooner you recognize the signs of dog dementia, the sooner your dog can get treated and live longer with a healthy mind.

What are the causes behind dog dementia?

The exact cause behind canine dementia has not yet been uncovered. However, a few theories are available. It is believed that the most common cause behind dog dementia is that with ageing, the physical and chemical changes which occur, cause the brain function to decrease. However, the cognitive decline related to age is not the only cause behind dog dementia. Other factors like brain tumors or genetic predisposition may also make your dog susceptible to developing dementia in advanced years.
