Dementia in dogs  

With an increasing life expectancy and general good health in dogs, symptoms like human dementia have been noted. It is estimated that 14-35% of all family dogs are affected, and about 50% of dogs over 14 years old. 

Previously, these behavioral changes were simply attributed to old age, but a clear pattern has now been identified in this group. Dog dementia, also known as cognitive dysfunction, involves a gradual degradation of brain tissue, which impairs the dog’s ability to perceive and interact with the outside world.

Early diagnosis and treatment are important! Some age-related changes are obvious, while others develop slowly over time and are therefore difficult to detect. A senior pet should have health checks at the vet. This can ensure a longer and better life. 


Your senior dog needs help with daily life. This can include:

  1. Dietary supplements 
  2. Changes in diet 
  3. Exercise – physical movement 
  4. Mental stimulation 
  5. Medication 


Talk to your dog’s veterinarian  

There are products and medications with several positive effects on circulation, heart, organs, and joints.

Regular exercise 

Make sure your dog’s mobility and coordination are challenged with regular exercise and play. 

Contact a specialist if necessary! 

For example, hydrotherapy treadmills, laser therapy, electrostimulation, and acupuncture can be efficient to ease dementia. 


Help your dog so it can easily get into the car, avoid slippery floors, and remove obstacles that the dog has difficulty handling.
