Cognitive Dysfunction in Dogs
Is Your Senior Pet "Just Getting Old" or is it Dementia? Understanding CDS in Dogs and Cats

If you’ve lived in West Union or anywhere around Adams County for a while, you probably know that we take our "senior" status seriously. Whether it’s a favorite tractor that’s seen better days or a faithful farm dog who’s been by your side through thirty-some harvests, there’s a certain respect for things that have "been there, done that."
But here at Adams County Veterinary Services, we’re seeing a trend that’s a bit of a silent killer of quality of life. Owners come in with their gray-muzzled companions and say things like, "Oh, he’s just slowing down," or "She’s just getting old and grumpy."
Here’s the sobering truth: a lot of those "old age" behaviors aren't just natural wear and tear. They are signs of Cognitive Dysfunction Syndrome (CDS). In plain English? It’s dog and cat dementia. And while it’s a serious, long-term illness, it doesn't mean your pet's story has to end prematurely.
Dr. Dan Meakin has been practicing for over 37 years, and if there’s one thing he’s learned, it’s that we can’t just write off our old friends because they’re getting a little confused. We have more tools in our arsenal today than ever before to help your pet stay "sharp as a tack" well into their golden years.
What Exactly is CDS?
Think of CDS like Alzheimer’s disease in humans. It’s a degenerative process where the brain starts to change, atrophy occurs, certain "plaques" build up, and the neurons just don't fire the way they used to.
It’s incredibly common. Studies show that nearly 28% of dogs aged 11-12 show signs of cognitive decline, and that number jumps to a staggering 68% by the time they hit 15 or 16. For our feline friends, about 35% of cats over age 11 are dealing with at least one sign of dementia.
The problem? Most owners, only about 7%, according to some surveys, actually mention these changes to us. We want to change that. Because the sooner we catch it, the more we can do to slow it down.

The "DISHA" Checklist: Is Your Pet Showing Signs?
To make it easy for our local pet parents to keep track, we use an acronym called DISHA. If you notice these things happening at home, don't wait. It’s time to bring them in to see Dr. Dan.
D – Disorientation
Is your dog standing at the hinge side of the door waiting to go out? Do they get "stuck" in corners or behind the sofa and seem unable to figure out how to back up? This kind of spatial confusion is a classic sign. Some pets will even stare at walls or "head-press" against furniture because they’re simply lost in a familiar environment.
I – Social Interactions
This is often the part that breaks an owner’s heart. Your once-cuddly cat might suddenly become irritable or withdrawn. Or, a dog that used to greet you at the door with a wagging tail might not even get up when you come home from work. Sometimes they even become aggressive toward family members they’ve known for years.
S – Sleep/Wake Cycle Disturbances
We call this "Sundowners" in humans. Your pet might sleep all day but then spend the entire night pacing, panting, or vocalizing. If your cat is yowling at 3:00 AM for no apparent reason, or your dog is "ghost walking" through the house while you’re trying to sleep, their internal clock is likely malfunctioning.
H – House Soiling
This is a big one. If a house-trained dog suddenly starts urinating right in front of you, or your cat stops using the litter box despite it being clean and accessible, they might have simply "forgotten" their training.
A – Activity & Anxiety
You might notice aimless wandering, repetitive behaviors (like licking a paw until it’s raw), or a sudden, intense fear of things that never used to bother them, like a thunderstorm or the sound of the vacuum. This "new" anxiety is a very common side effect of brain degeneration.
Diagnosis: Why Dr. Dan’s Experience Matters
Here’s where it gets tricky. A lot of things can look like dementia but actually be something else.
- Is your dog "disoriented," or do they just have cataracts and can't see?
- Are they "withdrawn," or are they in pain from undiagnosed arthritis?
- Are they "soiling the house," or do they have a urinary tract infection or kidney issues?
Dr. Dan Meakin specializes in these complex cases. Because he’s a general practitioner with the experience of a specialist, he knows how to rule out the "medical mimics" before we land on a CDS diagnosis. We’ll usually start with a full physical, blood work (to check thyroid and organ function), and a neurologic exam. We treat every patient like our own pet, ensuring we aren't missing a treatable physical ailment while we address the cognitive side.
The Modern Arsenal: Treatments for CDS
The bad news: we can't "cure" dementia. The good news: we can manage it brilliantly. We have three main ways to fight back:
1. Prescription Diets
What your pet eats matters for their brain. We often recommend specialized diets like Hill’s Science Diet b/d (the "brain diet") or Purina Pro Plan Veterinary Diets NeuroCare. These are packed with antioxidants (Vitamins E and C), Omega-3 fatty acids, and Medium Chain Triglycerides (MCTs) that provide an alternative energy source for the aging brain.
2. Targeted Supplements
Don't just grab something off a shelf at a farm store, you need the high-octane stuff that actually crosses the blood-brain barrier.
- Novifit (SAMe): Helps support brain and liver function and can decrease anxiety.
- Senilife: Contains Ginkgo biloba and Vitamin E to improve short-term memory and alertness.
- Neutricks: Uses a protein from jellyfish to help with learning and attention.
3. Medication (Anipryl)
Anipryl (Selegiline) is currently the only FDA-approved medication for dog dementia. It helps increase dopamine in the brain, which can significantly improve a dog’s "zip" and mental clarity. It’s also used off-label for cats with great success.

"Use It or Lose It": Environmental Enrichment
You wouldn't expect a human to stay sharp sitting in a dark room all day, and the same goes for your pets. Mental stimulation is medicine.
- Feeder Puzzles: Stop using a bowl! Make them work for their kibble with a puzzle toy.
- New Smells: Even a short walk to a different part of the yard can stimulate a senior dog’s brain.
- Gentle Training: Yes, you can teach an old dog new tricks. Keeping those neural pathways active is vital.
