Six Weeks After Disc Surgery and He Still Can't Walk: Is It Too Late, and What the Recheck Should Decide

Six weeks is the date the discharge sheets we read stop describing. It is not a date the recovery evidence recognises. If he was paralysed at surgery but still felt his toes, the pooled surgical record says 78% of dogs like him were walking by 4 to 6 weeks and 93% eventually; on our own arithmetic from that table, which pools series with different follow-up, about two in three of those still down at this point walked later. If he had lost deep pain sensation, the same table reads 42% at 4 to 6 weeks and 61% in the end, and, on our reading of the series behind it, some of the dogs counted as walking never regained feeling: they walked anyway, at a median of about nine months. The one true deadline in this disease, progressive myelomalacia, falls in the first two to three weeks and is behind you. What the six-week recheck should decide is which of those calendars he is on, whether his bladder is infected, and what the plan is for the months that may follow, including the cart.

The argument in the house#

By week six a household can split into two positions, and both are reasonable. One says it is time to accept what he is. The other says give him more time. Neither has a number, and the discharge sheet does not supply one. It said four to six weeks, it said rest, and it said recheck, and he is still being carried to the grass.

This page tries to supply one. It is not a comfortable number in every row, but it is a real one, and it turns the argument into a question the recheck can answer.

Where the six-week date came from#

It did not come from the recovery curve. It came from the disc.

The ACVIM consensus statement on thoracolumbar disc extrusion recommends at least four weeks of restricted activity after surgery, "putatively to promote healing of the annulus fibrosus," confined to a crate or a small room except for rehabilitation exercises and toileting, and it grades that recommendation as supported by low-level evidence.^[1] The same document's table of rehabilitation exercises gives durations, not deadlines. Range of motion and massage run "10 d to 6 wk or until ambulation or normal mobility," assisted standing "5 d to 6 wk," assisted walking over ground "4 to 6 wk or until ambulation." Other entries start in the first weeks and run longer: land treadmill walking "6 wk to 3 mo or normal mobility," manual gait patterning, which the table says can be done on a treadmill, in water or "cart/lift-assisted," from "3 d to 3 wk postop" for "6 wk to 3 mo or until ambulation or normal mobility," and water work "7 d to 3 mo."^[1] Six weeks, in other words, is where the shortest schedules in that table run out and where the owner sheets stop, while other exercises in the same table run to three months; the consensus itself puts a floor of four weeks on rest and no ceiling on recovery. Nothing in it says what a dog who has not walked by then will do next, and nothing in it says he will not.

The owner sheets say the same thing in plainer words. The Animal Clinic of Billings schedules an evaluation at 2 weeks and another at 4 weeks, and tells owners that "the first 4-6 weeks following surgery are very important," without saying what to conclude if the dog is not walking at the end of them.^[2] One surgical practice's client sheet says nerve function "should gradually return and improve over the coming days and weeks," and, further down, that "patients with prolonged or permanent rear limb paralysis may benefit from custom-made carts."^[3] Between "weeks" and "permanent" there is no sentence, and that gap is where you are standing.

Six weeks is the date the crate opens. It was never the date the recovery closes.

The one question that decides which clock he is on#

Everything below splits on a single fact from the neurological exam: whether he still felt a firm pinch of his back toes before surgery, and whether he feels it now. If you do not know what he had at surgery, ask the surgeon's office before the recheck. It is on the record.

The test is harder than it looks, which is why it belongs in the clinic. The Canine Spinal Cord Injury Consortium's prognosis review describes it in detail: pressure applied over the toe with "an instrument with relatively wide jaws such as needle drivers or pliers," increased until the dog shows he perceives it by vocalising, looking round or moving away, with both the inside and outside toes of each foot tested and the base of the tail as well.^[4] A leg that pulls back is not the answer. That is a reflex, and it happens without feeling. The answer is whether he notices: the cry, the turn of the head, the attempt to get away from the pinch.

“Because your dog can't tell you how much pain he or she is in.”

He cannot tell you whether he felt it. The recheck can.

If he still felt his toes: what the record says about week six#

The consortium review pooled the surgical case series into one table of recovery by time point. These are the rows that matter for a dog who could not walk before surgery.^[4]

Read the middle row for a dog who was paralysed with feeling intact. At 4 to 6 weeks, 78.2% were walking. Overall, 93% walked. The arithmetic the table does not print, and which is ours, is this: of every hundred such dogs, about 22 were still down at six weeks, and about 15 of those 22 went on to walk. Roughly two in three of the dogs in your dog's position recovered, but read where the rise sits: between 4 to 6 weeks and 3 months the table moves only from 78.2% to 83.2%, about 5 of the 22, and the rest appears in the overall column. The number is not a promise. The time-point columns and the overall column are pooled from case series that did not all follow the same dogs for the same length of time, and the review's authors say the figures come from observational studies, not trials.^[4] But it is the most carefully pooled number we found, and it is not the number the household has been arguing from.

The single series most often quoted for this group is Davis and Brown's 112 dogs, all non-ambulatory with feeling intact. In that series 96% walked within 3 months, the mean time to walking was 12.9 days, and it was 7.9 days in dogs who could move a leg after surgery against 16.4 days in dogs who could not.^[5] Your dog is past the mean, by a long way. That is not the same as being past the range: in the pooled table above, the walking figure for this group is still rising between 4 to 6 weeks and 3 months, from 78.2% to 83.2%, and higher again overall.

What the review says about these benchmarks is the most useful sentence on this page for a dog with feeling intact. The speed of recovery is "influenced by the severity of motor impairment at presentation, altering prognosis for walking at 2, 4–6, and 12 weeks," and "these benchmarks are extremely useful to indicate when a dog might not be recovering as expected, triggering a timely re-evaluation by the veterinarian."^[4] A dog with feeling who is not walking at six weeks is not a lost cause. He is a dog who has tripped a benchmark, and the response the review names is a re-evaluation, not a verdict. Go to the recheck expecting the surgeon to look harder, and if the examination cannot account for the delay, ask whether repeat imaging is warranted. We found no source that tells a surgeon when to re-image a slow recovery, so that is a question, not an instruction.

If he lost deep pain sensation: the longer calendar#

The bottom row of the table is the hardest to read, and it needs reading slowly, because it is two stories, not one.

The first story is recovery with feeling. Across the series, between 52% and 62% of dogs who had lost sensation before surgery walked again: 61% in the meta-analysis,^[7] 61.6% of 297 dogs within a year in the five-centre cohort,^[8] 52.1% of 211 in Aikawa's series.^[6] Most of those dogs got their feeling back first, and the timing of that matters more than anything else at six weeks. The review puts it this way: "once it is present, the prognosis for recovery of ambulation is excellent," and in the series it draws on, 62% of the dogs who regained sensation did so within 4 weeks, another 30% by 12 weeks, and one dog at 36 weeks.^[4] In an older series of 34 such dogs, 20 of the 21 that recovered showed feeling returning within two weeks of surgery.^[9]

So the first thing the recheck decides for this dog is whether feeling has returned. If it has, he has moved to the middle row of the table, with its 93%, and six weeks is early. If it has not, the series the review takes that timing from, the 2003 series in the table further down, found that 30% of those who ever regained feeling did so between weeks 4 and 12, which is the window you are now in, and one dog as late as 36 weeks: the chance falls, and it does not reach zero. The review gives percentages only, and its "one dog (8%)" means the timing describes a subset of about a dozen dogs rather than all 37 in that series who regained feeling; that reading is ours.

Done as the same arithmetic as before, and with the same caveat that it is ours: of a hundred dogs in the bottom row, about 58 were still down at 4 to 6 weeks, and about 19 of those 58 walked by the end of the series. One in three. That is lower than the row above, and it is far higher than the household's worst position.

One more number belongs here, for anyone carrying guilt about the first day. In a prospective cohort of 78 dogs without sensation, a greater delay between the onset of paralysis and the referral evaluation "was not associated with a poorer prognosis," and no factor the authors measured predicted which dogs would recover.^[10] That finding is about dogs who had already lost sensation, so it cannot say whether a faster start would have kept him out of this row. What it found is that among dogs already in it, a longer wait between paralysis and the referral visit was not associated with worse odds of walking. That is an absence of association in 78 dogs, not proof that the wait cost nothing, and it does not point at you.

Spinal walking: the recovery that arrives without feeling#

The second story in the bottom row is the one almost no discharge sheet mentions. Some dogs who never regain sensation walk anyway.

The consortium's review of this phenomenon calls it spinal walking, defines "chronic" loss of sensation as more than three months after injury, and says plainly that it "can take up to a year or more to develop."^[11] The numbers behind it come from two kinds of cohort, ordinary surgical series followed for years and two series built around intensive physiotherapy, and the honest reading is that they disagree about the calendar and agree about the fact.

Why do the calendars differ by a factor of three? The consortium's answer is selection and treatment: the dogs with the shortest time to walking "underwent early post-injury, intensive rehabilitation which might have positively impacted recovery."^[11] Gallucci's own authors are careful: the study had no control group, so it cannot show how much the physiotherapy did, and on their multivariable analysis younger dogs and lighter dogs were more likely to walk, with the analysis placing its cut-offs at 60 months and 7.8 kg; those are odds, not walls, and older and heavier dogs walked too.^[13] The Romanian series found the same shape: the dogs who walked had a median weight of 6.8 kg, the ones who did not, 15.6 kg.^[14] A small young dachshund and a middle-aged 20 kg dog are not reading the same table.

Two things have to be said plainly about this kind of walking. It is not the same as recovery: in the 2003 series, the dogs who walked without regaining sensation "remained incontinent," and among the dogs who did regain sensation, 41% had intermittent faecal incontinence and 32% intermittent urinary incontinence.^[12] And nobody has tested, against a control group, how to bring it on. The consensus panel says the evidence "is conflicting regarding the role for rehabilitation in these severely affected dogs," and notes, on the strength of one study each time, that intensive rehabilitation "might enhance the recovery of ambulation" in them and that among dogs who stay paraplegic, starting at about one week rather than three "might improve the likelihood."^[1] By six weeks that window has passed. The sensible response is not regret. It is to start now rather than at the next recheck, and our home physio page covers what that looks like between clinic sessions.

The deadline that has already passed#

There is one hard deadline in this disease, and it is worth naming so that it can be put down. Progressive myelomalacia, the ascending death of the spinal cord that develops in between 9% and 17.5% of dogs who lost sensation in most series and is fatal,^[4] with the review's full range running to 33%, and which accounted for 74 of the 297 dogs in the five-centre cohort, 25%, above that usual band,^[8] is an early event. In the 51-dog series that described its course, signs were present at the first visit in 17 dogs, had begun within 48 hours of presentation in 25, and in no dog began later than 5 days; progression to death or euthanasia ran from 1 to 13 days.^[15]

A dog who is stable at six weeks has passed the only part of this disease that runs on a clock measured in days. Everything that remains runs on months, and he is still here for it.

What the six-week recheck should decide#

None of the sheets we read says what this visit is for in a dog who is not walking, so this is our list, built from the consensus statement and the prognosis review. Take it in writing.

Should we buy a cart now?#

Here is what we could and could not find. No veterinary source we read names a week after surgery at which an owner should buy a cart. The consensus statement does list cart-assisted gait patterning among its rehabilitation exercises, starting 3 days to 3 weeks after surgery, but that is a cart or lift used to pattern steps during a therapy session, not a date for buying one.^[1] The same surgical sheet mentions carts for "prolonged or permanent" paralysis without defining either word.^[3] The cart maker Walkin' Pets' own IVDD page says crate rest is critical and that "you should not encourage your dog to exercise without veterinary approval," and recommends working with a vet or a wheelchair specialist; it gives no week either.^[16] Whether owning a cart and using it day to day helps or hinders the development of spinal walking has not been compared in any series we found. The one caution in the literature is indirect: Gallucci's authors suggest cage restriction may matter "to avoid dogs learning wrong behavior, such as freely dragging on their pelvic limbs."^[13] A cart stops the dragging. Whether it also stops the stepping, nobody knows. The other side of the ledger is the Romanian series, which held its dogs standing in "harnesses, trolleys, straps" as part of a programme after which 58% of them walked,^[14] so a wheeled frame is not foreign to the protocols that have been reported, though that series, too, had no control group. It is still not a comparison, because no dog in any of these series was assigned to go without one.

What the evidence does say is about owners. In a 2024 survey of caretakers whose animals used carts, quality of life was reported as improved in 62% of dogs and in 61% of their owners, but 64% of animals had at least one complication, and 53% of those complications were wounds.^[17] That is a self-selected owner survey, not a trial, and it is the only published number on the question that we found. Read it as: most caretakers reported a better quality of life for the animal, most animals ran into some problem with the cart, and the commonest problem was a sore. The survey does not say what caused the wounds. Fit is the part an owner controls, which is why the measurement below matters.

So, our reading, labelled as ours. For a dog who feels his toes and is improving week on week, a cart at six weeks is a purchase for a window that is probably closing. Spend the money on the rehabilitation referral instead. For a dog still without feeling at the recheck, who may be on the long calendar, a cart is how he gets to the park while it runs, and the decision belongs at the recheck, with the surgeon or the rehabilitation therapist measuring him, not with us.

Two cheaper things come first. The rear harness or sling you already own for toileting trips is enough for the garden, and for a dog small enough to carry, your hands and a towel are enough for anything. And the maker sells refurbished frames at a quarter off: the Medium we card, which is the frame for dogs of 26 to 49 lb, is $449 new, on Amazon and direct at the same price, and $336.75 refurbished from the maker on the day we checked. If your dog is lighter than that, and the dogs who spinal-walked in the series above skewed light, the maker's Small frame (11 to 25 lb) is $319 and its Dachshund frame is $319 for 11 to 40 lb, with a $249 frame for dogs under 10 lb that was sold out on the day we checked, all from the same adjustable family; buy those direct, because the card below is the Medium.^[21][18] If you buy, measure the rear leg from the top of the leg where it meets the belly to the toe pad with him lying down and some natural bend left in the leg, because that one number picks the frame, and the maker's return window is 30 days with an 8% restocking fee even on an unused cart.^[18][19]

We card it so that the measurement, the price and the return terms are in front of you on the day the recheck says yes, not so that you buy it before.

The reason we card a Walkin' Wheels frame is the adjustment, which the Small and Dachshund frames share. The dog you measure at six weeks is not the dog you will have at six months: if he is one of the dogs who walks, the cart is sold on; if he is not, he will lose muscle over the back end and gain it over the front, and a frame that, in the maker's words on the product page's own FAQ ("Why should I choose an adjustable wheelchair for my dog?"), "allows for 2-3 in of adjustability in both height and width, and even more in length," follows that without a second purchase.^[18] The downside is the price, and the Amazon buy box: on the day we checked it was held by a reseller called Veterinary Preferred rather than the maker, at the same $449.^[20] Buy direct, and buy refurbished if the maker has your size.

What we could not find#

• A maximum wait. No veterinary source names a week or month after which a dog who has not walked will not. The longest recoveries in the record are 36 weeks for feeling and 28 months for walking without it.
• A trial of carts. Nothing compares cart use with no cart in dogs recovering from disc surgery, for walking, for wounds or for spinal walking.
• A rule for re-imaging a slow recovery. The prognosis review tells the surgeon to re-evaluate when a benchmark is missed; it does not say what the re-evaluation should include.
• Any owner sheet that addresses this day. Both sheets we read describe the first six weeks. Neither describes week seven for a dog who is still down.

What to do this week#

The delay is the injury, and at six weeks it hides in a new place: the household's quiet agreement that the question has already been answered. It has not. It has been handed to a visit, and the visit will only answer it if you arrive with the right things.

So before the recheck, write three lines on the sheet that already holds the bladder times and the standing numbers: what he felt at surgery, if you know; the best movement you have seen in the back legs, with the date and a video; and anything new about his urine. Take the table above and ask its six questions in order. Then make the next stage a decision with a date on it, whichever stage it is: a rehabilitation referral booked this week if there is not one, and, if he has no feeling, a date three months from the injury, the point at which the consortium's review calls the loss of sensation chronic, at which the surgeon or therapist measures him for the cart and the pen and skin checks are set up for a long stay rather than a short one.

He cannot tell you whether he felt the pinch, and he cannot tell you he is still trying. Six weeks is when the crate opens. Let the recheck say what the next six are for.
