Can Dogs Get Dementia?

Yes. We are all aging - our dogs too. For our beloved geriatric pups aging can present as dog dementia. In dogs, dementia is usually referred to as cognitive dysfunction syndrome or cognitive dementia. Canine cognitive dysfunction is when aging dogs suffer from mental and behavioral decline associated with changes in their brains. This condition is quite similar, but is not exactly the same, as that in Alzheimer’s disease in humans. In humans, the damage in Alzheimer’s disease is permanent and irreparable.

In dogs, however, the outlook is more positive because behavioral signs of dementia are temporarily reversible and the progress of the disease can be slowed down.

Cognitive dysfunction results from changes in the brain associated with aging such as decline in neurons, decrease in cerebrovascular blood flow, or increase of neurotoin deposits. This result in the dog’s decreased responsiveness to stimuli, and decreased ability to learn and remember.

What are the Signs of Dementia in Dogs?

How do dogs act when they first get dementia?

In the early stages of dementia, the signs are often non-specific and are hard to attribute to any specific cause. Some indicators of dementia in dog may look like:

  • A decrease in energy and activity levels
  • Reduced social interaction
  • Loss of interest in play
  • Mild disturbance of sleep pattern
  • Mild increases in fear and anxiety
  • A loss of appetite

What Happens When a Dog has Dementia?

As the disease dementia progresses, you can observe more severe signs in your dog such as:

  • Changes in personality
  • Confusion and failure to interpret sensory information correctly (staring into space or at inanimate objects)
  • Loss of learned behaviors
    • House-training
    • Control commands
    • Food snatching and stealing in front of the owner
    • Elimination in front of the owner
    • Changes in emotionality
    • Worsening of existing fear and phobia problems
    • Increased anxiety
    • Depression
  • Impaired ability to new short-term memory
    • Repetition of behavior (e.g., requests for attention, food or to go outside)
    • Difficulty acquiring new learning (e.g., being house-trained again)
  • Specific neurological impairments
      • Loss of the ability to sense one’s position and movement
      • Central blindness (blindness caused by damage to an area in the brain)
      • Central deafness (deafness caused by defects in the central nervous system)

Caring for Dogs with Advanced Dementia

A Holistic and Alternative Care for Dementia in Dogs

Activity feeding- done by simply scattering dried food or freshly cooked bone for the pet to find. By doing nose-work exercises, your dog is having some olfactory stimulation, which may be one form of cognitive stimulation for your senior pet.

3 Cognitive Exercises to Practice with Dogs with Dementia

Walking your dog- gives your dogs a chance to sniff around and meet other dogs and people. Social interaction and exposure to new stimuli is important for keeping your dog’s cognitive skills sharp. If your dog has arthritis and has difficulty walking, using pet strollers is an option. She may not be getting aerobic exercise by using a stroller but she is using muscles involved in balance and attentiveness.

  1. Swimming- a good way to improve strength and stamina in older dogs that have become sedentary and unfit. Fitter animals can also enjoy more vigorous play and social contact with less risk of pain.
  2. Basic obedience or clicker work or working to teach new or maintain old tricks for 5 minutes 3-4 times per day. Some of the training can be incorporated into daily life (e.g. if getting up the table, you can ask the dog to come with you and sit or wait and offer a paw).
  3. Roll (instead of throwing) balls and Frisbees for your dog to chase and/or retrieve. You can also try rolling food toys, and puzzles. This will serve to enhance and maintain eye-paw coordination and because the toys/puzzles make noise, even dogs that are losing their sight and hearing acuity can benefit.

7 Best Practices aka Tips for Around the House For Dogs with Cognitive Dysfunction Syndrome (CDS)

Aged Dogs with dementia have problems locating and getting to the resources they need. You, as the owner, have to make some simple changes in the house to suit the need of your sick and aging pet:

  1. Provide additional water bowls close to your dog’s resting areas
  2. Provide additional resting sites
  3. Provide steps or ramps for your dog to easily get on and off furniture
  4. Use mats or rugs that have traction to help the dogs get more exercise and have fewer elimination accidents
  5. If your pet has problems with his/her vision, it might be helpful to put some carpets and rugs that will help your dog identify central floor spaces and corridors without bumping into things, place a quiet radio in different rooms close to his/her resources to help the dog identify the location, put different scents to help the dog identify specific rooms
  6. Provide a properly designed bed area, with a well-padded wrap-around basket that is near the night light and place your recently worn clothing to help an anxious or confused pet
  7. Protect the pet from accidents (e.g. falling into the swimming pool, falling down stairs).

How Does Food Quality Help in Preventing or Delaying Dementia?

It has been shown that specialized diets rich in antioxidants can slow down the progression of cognitive dysfunction, improve behavioural function and may have a protective effect [3, 4].A study showed feeding aged dogs with an antioxidant fortified diet (daily dose: 21 mg/kg/day Vitamin E, 1.6 mg/kg/day Vitamin C, 5.2 mg/kg/day Carnitine, 2.6 mg/kg/day lipoic acid w/ fruits and vegetables equivalent to 5-6 servings/day) resulted in a slowing of the rate of decline in cognitive abilities.

Furthermore, if the feeding of the antioxidant fortified food is started at a young age (2-4 years), this will result in significant improvement on a visual discrimination task compared to dogs of the same age that were fed with nonfortified food over the same time period.

This finding means that feeding foods that are fortified with antioxidants at an early age will delay the onset of cognitive decline in dogs.[6]

Dietary Treatment for Dogs with Dementia?

Dietary treatment for dogs with cognitive dysfunction is available. A commercially- available diet formulated for senior dogs (Hills Prescription Diet d/b) has been shown to improve memory, learning ability and clinical signs of cognitive dysfunction [9,3]. The diet is supplemented with antioxidants Vitamins E and C, selenium, beta carotene, and flavonoids and carotenoids, omega-3 fatty acids EPA and DHA. [9]Another diet shown to improve cognitive ability available in the market (Purina One SmartBlend Vibrant Maturity 7+ Formula) contains MCTs (medium-chain triglycerides). When fed to the aged beagles for 8 months, the dogs fed with the said diet scored significantly better on several types of cognitive tasks than did the control group. [1]The best time to implement dietary or supplement intervention is before the dog shows any signs of brain aging (4-5 yrs old for large dogs, 5-8 yrs old for medium dogs, no later than 8-10 years for small dogs).
