Your dog is turning into a senior. Here's what's already changing.
Your dog still greets you at the door, still eats fine, still looks like themselves. Underneath, activity, heart rate, breathing, and thirst are already shifting, months before anything looks obviously wrong. We measured it across 2,538 dogs. Maven measures it on yours, every night.
Aging in dogs isn't a guess anymore. We can see it happening.
We analyzed 2,538 dogs on Maven's WiFi collar, grouped into Adult, Senior 1, and Senior 2 by breed-adjusted age, to find out whether the collar actually detects aging or just guesses at it from a birthdate. It detects it. Here's what showed up.
Signs of aging in dogs that are easy to miss.
You see your dog every day, which is exactly why slow drift is so easy to miss. A little less activity this month, a little more water next month, nothing dramatic enough to notice on its own. These are the four changes that showed up most consistently in Maven's data, roughly in the order dog parents catch them.
Panting more than they used to
Some increase in panting is a normal part of aging, especially in warm weather or after activity. But a rising resting breathing rate, panting at rest with no obvious trigger, can also be an early sign of heart or pain-related changes. Maven tracks resting respiratory rate nightly, so you know whether it's a trend or a one-off.
Drinking noticeably more water
Across Maven's fleet data, drinking time nearly doubles by the advanced senior years, and it rises even in dogs with no diagnosed condition. Increased thirst is also a hallmark of kidney disease, diabetes, and Cushing's disease, all of which become more common with age, so a sustained increase is worth a vet conversation.
Slower on walks, less interested in play
A senior dog who tires faster or skips the last stretch of the walk they used to handle easily isn't just "getting lazy." Maven's data shows a 20 to 37% drop in daily activity by the senior years. Tracking it over time turns a vague feeling into an actual trend line you can act on.
Restless at night, or pacing and circling
Occasional restlessness can come from joint discomfort or a less restful night. But new, persistent pacing, circling, or seeming disoriented, especially in the evening, can also point to canine cognitive dysfunction (sometimes called doggy dementia or sundowners). If this is new and sticking around, it's worth flagging to your vet rather than waiting it out.
Why senior dogs benefit most from monitoring between vet visits.
Senior dogs rack up more consistent tracking days than any other life stage, because home health monitoring is exactly what senior dog parents already want. That's not a hunch, it's why this group keeps the collar on longer than anyone else.
Here's the gap it closes: a vet visit gives you one data point. A gradual 5% drop in activity, or three nights of slightly elevated breathing, is invisible to anyone who isn't tracking continuously. That gap between appointments is exactly where early senior changes are easiest to catch, and easiest to act on.
Build a real baseline before symptoms show
The earlier you start, the more useful the data. A dog's "normal" is personal, not a generic number, and Maven learns it in the first 7 days so future changes are measured against your dog, not an average.
Track how a new medication or diagnosis is going
Chronic condition rates climb sharply with age, about 20% of adults vs. 54 to 61% of senior dogs. If your senior was just started on a new medication, Maven's trend data shows whether it's working, not just whether your dog seems okay in the exam room.
Bring real data to every vet visit
"They've been a little more tired lately" is hard for any vet to act on. Weeks of actual trend data on activity, heart rate, breathing rate, and drinking gives your vet something concrete to work with at every senior wellness check.
Get a heads-up, not a scare
Maven alerts you when a reading drifts from your dog's own normal range. Not a panic notification, a heads-up with enough time to call your vet before a gradual change becomes an urgent one.
Independent researchers put Maven to the test. Here's what they found.
Does the collar actually catch a flare-up in real life?
Osteoarthritis is one of the most common conditions in senior dogs, and flare-ups are notoriously easy to miss day to day. Independent researchers, including three of Maven's own veterinarians, tracked five dogs with diagnosed OA for up to four months using the Maven collar.
Nine real clinical events happened during the study. In eight of them, the collar's activity data lined up with when the flare-up started, worsened, or improved. In one case, the drop in activity showed up before the owner noticed anything was wrong.
You know your dog better than anyone. That's not the same as data.
Most dog parents catch senior changes the same way: a feeling that something's a little off, checked against memory of how their dog used to be. It works eventually, usually right after the change is already obvious. Maven catches the same changes while they're still small.

Every senior dog ages differently. The first week, Maven learns what normal looks like for your specific dog, at their current stage, so later alerts mean something.
If activity, heart rate, breathing rate, or drinking drifts from your dog's personal normal, you get a notification, with enough time to act before it becomes urgent.

What senior dog parents say about Maven
"As he has entered his senior years, I've become much more aware of how important it is to catch health issues early. Instead of guessing, I know exactly how he is doing every single day. If there is even a slight shift in his breathing or a change in how much water he's drinking, I have the data to act immediately."
"I have a tracker on his respiratory rates, now heart, and a report on how much he's sleeping and drinking. Especially with kidney failure always being a concern with these guys, it helps me know he is keeping up with his water intake, and his activity report gives me an idea of his quality of life."
"I have a senior dog with some health issues. This app allows me to know when he is stressed or overexerting himself. I can respond to his needs better by observing changes in the app stats, and get a heads-up if he is starting to experience any issues."
