He Was Fine Yesterday. Today He’s Limping.

He gets up from his bed the way he has for a year now, stiff and in no hurry. Then he takes a few steps toward his water bowl, and one back paw barely touches the floor. Yesterday he was stiff first thing and loose by the second walk. This is new.

You have half an hour before you leave for work and one question: is this his arthritis having a bad day, or something else?

Most of us know the difference in our own bodies. The ache we’ve had for years waits for the next checkup. The one that showed up this morning, especially after a fall, gets a phone call today.

Your dog can’t tell you which kind this is. Here is how vets sort a limp by urgency, and what you can do while you decide. If you’re short on time, the signs that mean today are in the box just below.

Isn’t this just his arthritis acting up?

It might be, and that’s the trap. One of the first things a vet asks about a limp is whether it came on suddenly or gradually (Cornell Riney Canine Health Center). Arthritis is a chronic, progressive disease that usually develops gradually.

A limp that appeared overnight, or halfway through a walk, is a change, and a change gets checked on its own terms before it joins the old diagnosis. The stiffness that crept in over a year belongs at a routine visit.

A vet examining a limping dog checks the bones and joints, and also the nerves and spinal cord, because either can produce a limp.

For an older dog limping on a back leg, Cornell’s list of what vets consider includes a torn ligament in the knee, hip arthritis, spinal disease and foot injuries, among others. More than one can be going on at once at his age.

Telling them apart takes an exam. What you can work out at home is how soon he needs to be seen.

Which limps need a vet today?

Get him seen today, as soon as you can, if he shows any of these. The list comes from the emergency team at BluePearl, a network of specialty and emergency animal hospitals, in its Irvine hospital’s guide to limping (BluePearl):

• He won’t put any weight on the leg.
• He yelps or cries out when the leg is touched or moved.
• There’s swelling, bleeding, or an injury you can see.
• The limp started after a knock or an accident: a fall, a fight with another dog, being hit by a car.
• He’s dragging the leg or knuckling over onto the top of his paw.
• The limp comes with lethargy, fever, or shaking.

Add a dog who is wobbly or weak in more than one leg, has lost bladder or bowel control, or can’t stand up or walk. Southeast Veterinary Neurology (SEV), a specialty neurology practice, lists wobbling, weakness, incontinence and an inability to walk among the warning signs of disc disease in the spine (SEV). If your clinic is closed, any of these goes to an emergency clinic, today.

From the outside, the serious and the trivial can start as the same limp.

BluePearl’s team puts it plainly: sometimes a limp is nothing more than a sore paw, and sometimes it’s the first sign of a torn ligament, a fracture or an infection that needs treatment right away. The list is how they tell owners when it’s time to come in.

What if it isn’t the leg at all?

Three of the signs on that list, the knuckling, the wobble and the weakness in more than one leg, are more often signs of a nerve problem than a joint one. SEV explains why. Knuckling suggests he has lost track of where his paw is, not that it hurts. Legs that wobble or give out are weak or uncoordinated, where a sore leg is one he keeps his weight off. And while injuries and joint problems often involve one leg, many nerve problems affect two or four (SEV).

Any of those three means he should be seen today, starting with a call to your vet. Asked whether a sudden limp is serious, SEV’s neurologists answer “sometimes”: a dragging paw or weakness can indicate an urgent neurological problem.

There’s a catch if you’re hoping for good news. Some nerve problems can be very painful, a slipped disc among them, while others can leave a dog weak without obvious pain.

That’s why, SEV writes, some of these dogs still seem bright, happy and eager to move while their gait is clearly abnormal. A cheerful dog is good to see. It doesn’t tell you the walk is fine.

If he has lost the ability to move his legs, SEV is blunt: don’t wait. For a dog whose disc problem has already left him unable to move, it writes, each hour is critical to his recovery (SEV).

When is it okay to watch and wait?

For a mild limp, sometimes. Limping is fairly common in dogs and isn’t always an emergency, BluePearl’s team notes; a minor strain, a sore paw or a little too much play can cause a limp that passes (BluePearl).

Their criteria for watching at home: the limp is mild and gets better with rest, he doesn’t seem bothered when the leg is touched, and he’s otherwise eating, playing and acting normally. Watching means rest and leash walks only, for a day or two. If the limp doesn’t improve or gets worse, he needs to be checked.

Cornell’s center is firmer. A limp that has lasted more than a day or two, or pain that is severe, sudden or getting worse, shouldn’t wait (Cornell). SEV’s list of reasons to see your vet adds a limp that affects more than one leg, or comes with weakness, knuckling or dragging (SEV).

So for a limp that came on suddenly, the waiting starts with a phone call. Describe it to your clinic, and if they agree it can be watched, give it the day or two. Watching is then a plan with an end date: rest, the leash, and an hour you’ve already picked to call back if he hasn’t improved.

Those timelines are rules of thumb from clinicians, not cutoffs from a study, and no list you run at home sorts every limp correctly. Limping is one of the most common reasons owners call BluePearl’s Irvine emergency line, its team notes. When you can’t tell what you’re looking at, call and describe what you see.

What should I do in the meantime?

Keep him quiet: short leash walks to relieve himself, no jumping on the bed, and no stairs if you can avoid them. If he’s wobbly, knuckling or weak in more than one leg, keep him confined until he’s seen, which in that case means today. SEV’s advice is crate rest (SEV); without a crate, a small space where he can’t run, jump or climb is the closest thing.

If he’s already up and moving, take a short video. Cornell’s center calls home videos of a limp “extremely helpful,” partly because some dogs walk normally once they reach the clinic, out of excitement or adrenaline. Don’t walk a sore dog around just to film him.

Note when the limp started, what he was doing just before, and whether it’s getting better, worse or moving between legs. Your vet will want to know all three (Cornell).

Any pain relief should come from his vet. Keep your own painkillers out of it unless the vet says otherwise: some of the ones people take are toxic to dogs, and the damage can start before any sign shows.

So what do you do this morning?

Watch him cross the room once more, without coaxing. If anything from the vet-today list is there, from a leg he won’t stand on to a paw that drags or a wobble in more than one leg, call now.

If none of it is, and he’s putting some weight on the leg and eating his breakfast, call the clinic before you leave. Describe what you saw and ask whether it can be watched. If they say yes, he gets a quiet day on a short leash. Before you hang up, pick a time to call back, and call right away if he gets worse.

On a day he’s moving his usual way, film him crossing the room for twenty seconds and keep it. If his walk changes again, your vet will have a before to compare it with.

Common questions

My dog limped for a few minutes and now he’s fine. Should I still call?

If the limp followed a fall, a fight or a car, call your vet today, even if it has cleared. Otherwise, a limp that passes quickly can come from something minor, such as a small strain or a sore paw, according to BluePearl’s emergency team, which also notes that some limping points to deeper problems. Keep an eye on him. Call your vet if the limp comes back, and get him seen today if it returns with any other sign from the vet-today list.

My dog is limping but doesn’t seem to be in pain. Is that okay?

A dog who limps without seeming to hurt can still need a vet. Some nerve conditions affect movement or limb control without obvious discomfort, according to Southeast Veterinary Neurology, and a dog who is hurting may not show it plainly. If the limp comes with knuckling, dragging or weakness in two or more legs, get him seen today. If it came on suddenly, call your vet first. Book a visit if he’s still limping after a day or two, and call the same day if it gets worse.

Can it wait until my vet opens in the morning?

A limp that comes with a leg he won’t stand on, a dragging paw, weakness in more than one leg, swelling, bleeding or a cry when the leg is touched shouldn’t wait for morning: if your clinic is closed, take him to an emergency clinic. If the limp is mild, gets better as he rests, and he’s eating and acting normally and isn’t bothered when the leg is touched, it fits the criteria BluePearl’s team gives for watching at home. If it came on suddenly, phone the emergency clinic first and ask whether it can wait for morning. If they say it can, or it came on gradually, keep him quiet overnight and call your vet when the clinic opens. If it gets worse in the night, take him to the emergency clinic; if you can’t tell, call them and describe what you see.
