Bilateral Tear Prevention Vault

The 9 early signs the good knee is struggling, and what to do the week you spot one.

A 5-MINUTE READ · FROM THE KILDE TEAM
Read this first

The knee you're not watching is the one doing all the work.

After a cruciate tear or a TPLO, every eye in the house is on the repaired leg. Meanwhile the other back knee quietly carries the extra load: getting up, stairs, the jump off the couch, every potty break during crate rest.

1 in 3+Studies estimate somewhere between a third and half of dogs that tear one cruciate go on to tear the other.
MonthsA second tear usually follows weeks to months of slow, quiet strain, not one bad step.
EarlyThe warning signs show up first at home, long before a vet visit. You just have to know what they look like.

This Vault is built around one idea: you are the person most likely to catch it early. You see your dog get up, sit, eat and climb stairs every single day. The 9 signs below are the small changes owners most often look back on and say, "that was it, I just didn't know."

How to use the Vault

  1. Read the 9 signs once (about 5 minutes).
  2. Do the 2-minute weekly check below. Same day each week, same room, same time of day.
  3. Use the traffic light to decide when to just watch and when to call your vet.
  4. Make the easy home swaps at the end so the good knee has less to carry.
The 9 early signs · 1–4

Watch how they sit, stand and stand up.

1

The "lazy sit"

Instead of tucking both back legs neatly underneath, your dog sits with one back leg kicked out to the side. A healthy knee folds all the way. A sore one doesn't want to.

Check: ask for a sit on a non-slip floor and look from behind. Note which leg sticks out, and whether it's new.
2

Weight shifting while standing

Standing still, your dog keeps easing weight off one back leg: the paw rests lightly, the toes barely touch, or they keep shuffling their back feet.

Check: watch the back legs while they eat. Both paws should be planted flat and even for the whole meal.
3

Stiff first steps after rest

The first few steps after a nap or first thing in the morning look stiff or short, then "warm out" after a minute. Owners often write it off as getting older.

Check: watch the first 10 steps after a long rest. Stiffness that's new or getting longer is the signal.
4

Getting up front-end first

Your dog pulls themselves up with the front legs and drags the back end along, or needs two or three tries to stand from lying down.

Check: watch them stand from their bed. A healthy get-up pushes from the back legs in one smooth move.

Watch what they stop doing.

5

Hesitating at stairs, the car or the couch

A pause before the stairs, a new "wait for help" look at the car, or simply not jumping on the bed anymore. Dogs avoid what hurts long before they limp.

Check: make a note of anything they used to do on their own that they now hesitate on or skip.
6

A skip or short step after exercise

Fine on the walk, then a quick hop, a shortened step, or a toe-touch on the good leg afterward, especially after running, zoomies or a slip.

Check: watch the 15 minutes after activity, not just the walk itself. That's when it shows up.
7

Thigh muscle changing

The thigh on the good leg feels softer or smaller than it did, or the difference between the two back legs changes. Dogs often lose muscle on a leg they've started protecting.

Check: once a week, run both hands down both back thighs at the same time and compare. A soft tape measure at the same spot makes it easy to track.
8

Puffiness or a click at the knee

The inside of the knee looks or feels thicker than the other side, or you hear a click when they walk. Either one is worth a vet visit soon.

Check: gently feel both knees side by side while your dog is relaxed. Compare shape and warmth. Don't force the joint to bend.
9

Licking, restlessness, sitting down mid-walk

Licking at the knee, pacing or struggling to settle at night, or stopping to sit or lie down on walks they used to finish easily.

Check: notice whether walks are getting shorter, or nights more restless, over a couple of weeks.
The 2-minute weekly check

Same day. Same room. Same time.

Doing the check the same way each week is what makes small changes stand out. Tick anything you see, and jot a note on your phone with the date.

Sit: both back legs tuck under evenly (sign 1)
Stand: both back paws flat and even while eating (sign 2)
First steps: smooth from the first step after a nap (sign 3)
Get-up: pushes up from the back in one move (sign 4)
Stairs, car, couch: no new hesitation (sign 5)
After exercise: no skips or short steps (sign 6)
Thighs: both feel the same as last week (sign 7)
Knees: same shape and warmth, no clicking (sign 8)
Behavior: no new licking, restlessness or shorter walks (sign 9)

Take the load off

5 easy home swaps for the good knee.

No new routines to keep up. Set these up once and they protect both knees every day.

1

Cover the slick floors

Runners or rugs on hardwood and tile, especially where they get up, turn and eat. Slips are one of the most common moments a strained knee gives out.

2

Add a ramp or steps

For the couch, bed and car. Jumping down puts a big, sudden load on the back knees.

3

Keep them lean

Every extra pound is carried by the knees on every step. Ask your vet what a healthy weight looks like for your dog.

4

Steady beats sudden

Regular leash walks every day are kinder to knees than quiet weekdays and big weekend runs. Skip ball-throwing and sharp turns until your vet says otherwise.

5

Keep paws gripping

Trim nails and the fur between the paw pads so their feet grip the floor instead of sliding.

Your Kilde One™ routine

Both back knees, 10 minutes, while they rest. Nightly for the first 8 weeks, then 1–2 sessions a week. Just had surgery? Start on the good knee and add the repaired knee once your vet clears the incision area.
