Senior Dog Health Monitoring: the OEM Opportunity in Canine Cognitive Decline

Your customer's dog is slowing down. Your product line doesn't know it yet.

Fifty-five percent of dog-owning households in the United States now have at least one senior dog, age seven or older. The number has been going up for a decade. In 2012, that number was at 41.6%. To put it in raw numbers, 26.5 million American households are caring for an aging dog.

The difference between these owners and casual buyers is they are spending more on veterinary care, supplements, therapeutic diets, mobility products, and more. They are anxious and actively looking for products that help them.

Right now, the senior dog health monitoring market is the largest underserved buyer segment.

The Senior Dog Problem Explained

The American Animal Hospital Association published its 2023 Senior Care Guidelines for Dogs and Cats, and one finding stands out for product strategists: senior pets represent 44% of the active veterinary patient population in the United States, based on VetSuccess data covering over 14 million veterinary patients.

That is not a niche. That is the single largest clinical group walking through vet clinins. Most of them complain about uncertainty. The dog seems off. Something has changed in their dog’s behavior. Most importantly? They cannot pin it down to what happened.

A senior dog's health does not decline in steps. It drifts. Resting heart rate creeps up by a few beats per minute over months. Respiratory rate shifts during sleep. Heart rate variability narrows as autonomic function declines. Sleep architecture fragments. Pet owners cannot notice these changes by sitting on the couch and cuddling with their dog. They are measurable.

Right now, most pet health products on the market measure the wrong layer. Activity trackers measure steps and calories. GPS collars track location. But what about the physiological signals that change when a senior dog’s health is deteriorating? Nothing!

Senior Dog Cognitive Dysfunction

Canine cognitive dysfunction syndrome (CDS) is one of the best illustrations of this gap.

The Morris Animal Foundation reports that CDS prevalence ranges from 14% to 35% in dogs aged eight and older. One study cited by the Foundation found the prevalence was 28% in dogs aged 11 to 12, jumping to 68% in dogs aged 15 to 16.

Here is the part that matters for product companies. The single most impaired behavioral domain in CDS, across multiple studies, is sleep-wake cycle disruption.

Veterinarians suggest to to follow dogs over time during their adult and senior years to determine if there are any early markers in their sleep-wakefulness patterns, or in the electrical activity of their brain during sleep. That is where the opportunity lies for pet tech companies.

What Monitoring Matters for Senior Dogs

A senior dog health checklist, the kind that AAHA and the BSAVA's Ageing Canine Toolkit (ACT) recommend owners complete every six months, asks about mobility changes, weight changes, dental health, behavioral shifts, and confusion. These checklists are useful. They are also entirely subjective. Pet owners can note only what they see, and what they remember about six months ago.

During that period, there are physiological signals that change like resting respiratory rate, heart rate variability, sleep architecture, resting heart rate trends, and more. Activity trackers and GPS collars cannot measure these signals.

For pet brands evaluating the market, the question is different from a consumer buying decision. The question is: can you build a health monitoring product for senior dog owners on someone else's consumer platform? The answer is no. You need OEM hardware you can brand, customize, and integrate into your own product ecosystem.

PuresPet PHH-23: BCG-Based Monitoring Built For OEM

PuresPet's PHH-23 is a non-wearable health monitoring device that uses ballistocardiography (BCG) to capture heart rate, respiratory rate, heart rate variability, and sleep data from beneath a dog's resting surface.

BCG works by detecting the micro-vibrations produced by cardiac contractions and respiratory movement as they transmit through the body. The PHH-23 uses flexible piezoelectric and bone conduction BCG sensors that penetrate fur without requiring skin contact, adhesive patches, or shaved areas.

That distinction matters for the senior dog use case specifically. The device sits under the dog's bed or resting pad. The dog lies down. The monitoring starts. There is no collar to cause irritation, no charging routine to forget, no compliance gap when the owner removes the device for a bath or a vet visit. For a senior dog who spends 14 to 18 hours a day resting, the PHH-23 captures physiological data during the exact hours when the most clinically relevant changes occur.

What the PHH-23 tracks continuously:

• Heart rate and heart rate trends over time
• Resting respiratory rate (the metric the EPIC study identified as critical for CHF detection)
• Heart rate variability (the stress and autonomic function biomarker validated against ECG in the Chuluunbaatar et al. 2025 study)
• Sleep duration, fragmentation, and nocturnal movement patterns
• BCG waveform data for deeper physiological analysis

PuresPet describes itself as the only BCG vital signs monitoring device in the pet health space. That is a verifiable claim worth checking against CareSix (a South Korean company that integrates BCG into a wearable collar form factor, the Sense 1), but the PHH-23's non-wearable pad design is distinct from any collar-based BCG implementation.

The OEM Conversation You Need

PuresPet is not selling the PHH-23 direct to consumers. They are an OEM/ODM manufacturer with vertically integrated production covering sewing, plastics, silicone, metal fabrication, software, PCBA production, and reliability testing under one roof.

For pet brand founders and product leaders, that means:

Customization depth. The hardware, firmware, and companion app can be configured to your brand. You are not reselling someone else's consumer product with a sticker on it. You are sourcing a monitoring platform that carries your name, your UX, and your data.

Senior-specific product positioning. A pet brand that sources the PHH-23 can build an entire senior dog product line around it: a monitoring pad bundled with a therapeutic bed, paired with a senior health dashboard app, integrated with a supplement subscription. The hardware becomes the data layer underneath a product ecosystem, not a standalone gadget.

Veterinary data integration. The PHH-23's continuous data output creates a record that an owner can share with their vet. Instead of "he seems more restless at night," the conversation becomes: "his resting respiratory rate has increased from 18 to 24 breaths per minute over the last three weeks, and his sleep fragmentation score has gone up." That changes the clinical conversation. It also changes the perceived value of your brand.

The Market Math

The pet wearable market was valued at $3.14 billion in 2025 and is projected to reach $7.23 billion by 2031, at a 15.21% CAGR (Mordor Intelligence via Research and Markets, May 2026). The medical diagnosis and treatment segment is the fastest-growing application category, outpacing GPS and activity tracking.

Within that market, P&S Intelligence reports that vital sign monitoring held 42% market share in 2025, and disease and anomaly detection is forecast to grow at a 16.7% CAGR through 2032.

Now overlay the demographic data. Over half of dog-owning households have senior dogs. Eighteen percent of dog owners report their pets have aging-related special needs (Packaged Facts, February 2022). Senior pet foods are already used by 19% of dog owners. The buyer is already spending on senior-specific products. The monitoring hardware to serve that buyer exists. The brand that connects the two has a first-mover advantage in a segment that every major pet company will eventually enter.

Frequently Asked Questions

At what age is a dog considered senior?

It depends on size. The 2023 AAHA Senior Care Guidelines classify small dogs (under 20 lbs) as senior around 7 to 10 years and geriatric after 11. Large and giant breeds reach senior status earlier, around 6 to 8 years. The CCDS Working Group guidelines (JAVMA, 2025) recommend annual behavioral screening starting at age 7 across all breeds.

What are the first signs of cognitive dysfunction in dogs?

The DISHAA framework, developed by veterinary behaviorist Dr. Gary Landsberg, identifies six domains: Disorientation (getting stuck behind furniture, staring at walls), Interaction changes (withdrawal from family, loss of playfulness), Sleep-wake cycle disruption (restlessness at night, daytime sleeping increase), House soiling (accidents in previously trained dogs), Activity changes (pacing, repetitive behavior, or sudden inactivity), and Anxiety (new fears, separation distress). Sleep-wake disruption is consistently the most impaired category across published prevalence studies.

Can you monitor a senior dog's health at home?

Yes, but the quality of monitoring depends on what you measure. AAHA and the BSAVA Ageing Canine Toolkit recommend owners complete subjective health checklists every six months. Continuous physiological monitoring (heart rate, respiratory rate, HRV, sleep patterns) provides objective data between vet visits. BCG-based devices like the PuresPet PHH-23 capture these signals passively from a resting surface without requiring a wearable.

How common is dementia in older dogs?

Prevalence estimates vary by study and age group. The Morris Animal Foundation cites a range of 14% to 35% in dogs over eight, rising to 68% in dogs aged 15 to 16. Colorado State University puts the figure at 35% of dogs over eight years old. A Chulalongkorn University study found 52.4% of dogs seven and older showed signs consistent with CDS. Underdiagnosis is a consistent finding: the Chulalongkorn study reported that only 30% of owners were aware the condition existed.

Is there a checklist for senior dog health?

Two widely used tools exist. The DISHAA Canine Cognitive Dysfunction Assessment Tool scores behavioral changes across six domains on a severity scale (mild: 4-15 points, moderate: 16-33, severe: 33+). The BSAVA Ageing Canine Toolkit (ACT) is a broader home triage checklist covering mobility, dental health, weight, behavior, confusion, toileting, lumps, and quality of life, designed to be completed every six months with color-coded urgency ratings.

What vitals should I track in a senior dog?

The four most clinically relevant continuous metrics for senior dogs are resting respiratory rate (early indicator of cardiac disease and fluid buildup), heart rate variability (marker of autonomic function, stress, and pain), resting heart rate trends over time (gradual increases signal systemic problems), and sleep quality and fragmentation (correlated with cognitive decline per the NC State polysomnography study). Activity level is useful as a supplementary metric but is not a substitute for physiological monitoring.
