Symptoms of Alzheimer’s in dogs

Our dogs live more and more thanks to our care and it is not uncommon to see dogs of 18 or even 20 years. But this prolongation of their lives has consequences, and although few people know, dogs also suffer from an illness equivalent to Alzheimer’s of humans: the syndrome of cognitive dysfunction.

Cognitive dysfunction syndrome affects dogs between the ages of 11 and 15 depending on the breed. It is a progressive neurodegenerative disease that affects the various functions of our dog’s nervous system: memory, learning, awareness and perception may be altered.

In this article of Animal Expert we will tell you the symptoms of Alzheimer’s in dogs so that you will be able to recognize it if someday your dog will suffer from this terrible disease.

Activity changes

It is common to observe changes in the behavior of dogs affected by cognitive dysfunction syndrome: we can observe our dog walking aimlessly at home, or vocalizing for no apparent reason.

We can also see it with our gaze fixed on the void or notice a diminished curiosity, lack of reactions to outside stimuli, or even notice that our dog is apathetic and no longer clean. Another behavior noted by dog ​​owners with Alzheimer’s is excessive licking of objects or the dog owners themselves.

Change in appetite

Depending on the cases, puppies suffering from Alzheimer’s may have a decreased or increased appetite . They may also change food habits, and eat objects.

It is very important to pay attention to this aspect as we should make sure that our dog feeds. To do this we must tell you where the food is and even in some cases we should wait to make sure you eat what you should.

They are perturbado

Sleep periods increase in the dog suffering from Alzheimer’s, and sleep at night is of poor quality. When the sleep cycle is changed, the dog will wake up frequently at night and sleep during the day to compensate. Sometimes when you wake up at night it may bark for no reason.

Modification of social interactions

Alzheimer’s dogs lose interest in their owners, since they are not happy when we get home or when we caress them, do not seek attention and do not seem to be interested in caresses, while at other times they demand constant and excessive attention .

Often these dogs will stop playing with the owner and their toys. They may forget the hierarchy established in the family, and even not recognize their owners , not be receptive, and sometimes their aggressiveness toward other dogs may increase.


A dog suffering from Alzheimer’s loses the sense of orientation and can be lost in places that were previously familiar to him and used to know well both inside and outside the home. It can get locked in a corner or in front of obstacle instead of passing to the side.

Our dog may have trouble finding the doors, or waiting in the door for the wrong doors to get out of the way. He walks aimlessly and seems lost inside a familiar space.

Loss of your education

We might suspect that our elderly dog ​​suffers from Alzheimer’s if it no longer responds to the commands it once knew. They can often forget about customs such as urinating and doing their needs away from home, and they can even go out into the street and go inside and urinate already in the house . In the latter case it is important to prove that it is not some other illness related to old age.

What to do if your dog suffers from Alzheimer’s

If you suspect your dog is suffering from Alzheimer’s, you should call the veterinarian to confirm the diagnosis and give you advice and recommendations for your particular case. As a general rule we should help our dog at all times, especially watching for him to feed himself, be comfortable in the house and we should never leave him loose in the park or other places: it is very important to prevent a possible loss.

We should also try to give her affection and attention, although she probably will not recognize us, try to convey security and encourage the dog to play. Discover in the Expert Animal articles that will be very useful to you if you have an elderly dog:
