Puppies need a lot of stimulation and attention. As they age, maintaining their cognitive health is just as or more important than ever. And nutrition can be a great aid when it comes to their health.

In this blog, we'll tackle the best dog dementia diet.

Just like humans, dogs' cognitive health can decline over the years. You'll notice your senior dog to be more lethargic and not getting excited anymore.

All dogs tend to slow down during their senior years. However, as dog parents, we should help them and try ways to prevent cognitive problems such as dog dementia or cognitive dysfunction syndrome (CDS).

Proper diet and supplements can play a huge part in helping canine cognitive functioning and aiding with a dog's aging brain.

Nutrition is one of the most essential factors a pet owner should look into. Foods for dogs with dementia are easy to find, but they can be a bit costly.

But together with exercise and training, the proper diet holds a big picture on a dog's overall health.

In this blog, we'll talk about foods and supplements that are best suited for dogs with CDS. These are foods not only for dogs that have dementia but also to prevent CDS in their senior years.

But first, let's discuss what is Cognitive Dysfunction Syndrome or Dementia in dogs.

dog dementia stages

Dog Dementia Diet: What is Cognitive Dysfunction Syndrome?

Dog Dementia, also known as Canine Cognitive Dysfunction or Canine Cognitive Dysfunction, is a cognitive issue in dogs that is equivalent to Alzheimer's disease in humans.

This disorder is related to the dog's brain, causing behavioral changes and greatly affecting memory, learning, and comprehension.

According to research, dogs' risk of dementia increases by 50% every year! By the age of 15, about 68% of dogs get CDS.

Unfortunately, the exact cause of dementia in dogs is still currently unknown. However, it is often caused by physical and chemical changes that happen with the aging process, predisposed by brain tumors and injuries, or simply inherited from those developing the disease.

Cognitive Dysfunction Syndrome Symptoms

The acronym “DISHAAL” is often used to describe the symptoms of dog dementia. DISHAAL stands for:

  • Disorientation
  • Interaction changes
  • Sleep/Wake Cycle Disturbances
  • House soiling
  • Activity changes
  • Anxiety
  • Learning/Memory changes

But that's not all; other signs of CDS can be:

  • Unable to recognize familiar people or other pets
  • Pacing
  • Staring blankly at nothing
  • Lethargy
  • Lack of self-grooming
  • Excessive licking
  • Loss of appetite
  • Night walking
  • Night vocalization

How Diet Affects Your Dog's Cognition

Nutrition plays a big factor in keeping our bodies healthy. And that's the same with dogs.

In this day and age, there are now foods that are primarily aimed at managing heart problems, diabetes, inflammation, and other health issues.

Also, there are now supplements and dietary additions for dogs that can help improve their physical and mental condition.

So how does food affects a dog's cognition? Well, studies show that compounds such as alpha-lipoic acid and L-carnitine can help maintain cognitive function that's connected to aging.

There are also antioxidants like vitamins E and vitamin C that help shield cells from radical damage.

If you want to prevent your dog from experiencing CDS, try switching its diet to foods rich in cognition-boosting compounds.

So, what are other cognition-boosting foods and supplements? Scroll down, and let's find out!
