You Don't Need Fancy Equipment to Monitor Joint Health
After Biscuit's arthritis diagnosis, our vet told me something that stuck: "The best diagnostic tool you have is your phone camera and a set of stairs." She wasn't being dismissive. She was being practical. Because the truth is, tracking changes over time is more valuable than any single vet visit, and you can do it at home with almost no effort.
The Stair Test, Explained
Here's the concept. Once a month, you record your dog going up and down a set of stairs. Same stairs every time. Same angle. Same conditions as much as possible. Then you compare the videos over months.
That's it. It sounds almost too simple to be useful, but let me tell you why it works.
What You're Looking For
When you watch the videos side by side, you're tracking several things:
- Hesitation. Does your dog pause at the top or bottom before starting? How long?
- Gait pattern. Are they taking stairs one at a time or bounding? Are they using all four legs evenly or favoring one side?
- Speed. Not in a competitive way, but as a general indicator. A dog who used to trot up stairs and now walks deliberately is telling you something.
- Body posture. Are they leaning to one side? Keeping their head low (which often indicates pain)? Bunny hopping with the back legs instead of alternating?
- Willingness. Do they approach the stairs eagerly, neutrally, or reluctantly?
How to Set It Up
Pick a set of stairs your dog uses regularly. Indoor stairs work great because lighting and conditions stay consistent. Here's the simple protocol:
- Film from the side if possible, about 6 to 8 feet back, so you can see the whole body
- Record both going up and coming down
- Do it at the same general time of day (morning stiffness will skew results if you test at 6 AM one month and 3 PM the next)
- Don't lure them with treats or toys for the test. You want their natural pace and willingness
- Save the videos in a folder on your phone labeled by date
I do mine on the first Sunday of every month. It takes about 90 seconds and I've been doing it for five months now.
What the Videos Have Shown Me
Looking at my October video versus my most recent one, the difference is visible. In October, Biscuit was taking the stairs slowly, one step at a time, with a noticeable pause at the bottom before starting up. Her back end looked stiff.
In my most recent video, after months of weight management, joint supplements, controlled exercise, and environmental changes, she's moving noticeably smoother. Still not bounding up like she used to, but the hesitation is gone and her gait is more fluid.
Without those videos, I'm not sure I would have recognized the improvement. When you see your dog every day, even positive changes can be invisible.
Beyond Stairs: Other Simple Tests Worth Tracking
The stair test is the easiest and most revealing, but there are a few other things worth recording periodically:
The Stand Up Test
Film your dog getting up from a lying down position on a hard floor. Count the seconds from first movement to fully standing. In a healthy dog, this should be nearly instantaneous. In a dog with joint issues, you'll see a process: rolling, pushing, adjusting, pausing. Track this number monthly.
The Circle Test
Watch your dog turn in a tight circle (like they do before lying down). A dog with healthy joints and spine will turn fluidly in both directions. A dog with pain or stiffness will often have a "bad direction" where they turn wider, slower, or less willingly.
The Sit Test
Ask your dog to sit and watch how they do it. A normal sit is square, with both back legs tucked evenly under the body. Dogs with hip or knee pain often develop a "lazy sit" or "puppy sit" where one or both legs splay to the side. If your dog used to sit normally and has shifted to a sloppy sit, that's worth noting.
Taking Your Data to the Vet
Here's where this really pays off. When you walk into your vet's office with five months of video and notes, you're giving them objective data instead of subjective impressions. "She seems stiff" becomes "her stand up time has increased from 2 seconds to 5 seconds over five months, and she's developed a right sided lazy sit."
Every vet I've talked to says they wish more clients did this. It makes diagnosis easier, treatment monitoring more accurate, and helps catch regressions early.
When to Escalate
Your monthly tracking is for trend monitoring. But certain things warrant a vet call sooner rather than later:
- Sudden change in stair ability (could indicate an acute injury, not just progression)
- Consistent worsening month over month despite management
- New limping or non weight bearing on any leg
- Yelping or vocalizing during movement
- Sudden reluctance to move at all
Gradual changes tracked over time? That's your monthly monitoring working. Sudden changes? That's a vet visit.
Start Today
Seriously, right now. Grab your phone, go to your stairs, and record your dog going up and down. Save it with today's date. You've just created your baseline. Future you is going to be incredibly grateful for that 90 seconds of effort.
This is one of those things that costs nothing, takes almost no time, and gives you genuinely useful information about your dog's health over time. There's no reason not to do it.
