Arthritis in dogs: the subtle signs, what really helps, and how to support your dog at home

Arthritis in dogs almost always goes unnoticed at first, because a dog in pain does not whine: it gets up a little more slowly in the morning, gives up on the sofa, lags at the end of the walk, and we put it down to age. Yet osteoarthritis is the joint disease most often diagnosed in dogs, and the good news is twofold: it can be controlled very well, and what works has been measured. A few per cent of weight lost already reduces lameness; omega-3s improve weight bearing in four dogs out of five in a controlled trial; a monthly injection relieves almost one dog in two. The subtle signs to spot, the treatments with proven results, the home to adapt room by room, flare-ups, and quality of life over the years.

What is arthritis, and which dogs get it?

In a healthy joint, the bones glide over each other on smooth cartilage, bathed in a lubricating fluid. In osteoarthritis, this cartilage wears and cracks, the bone underneath reacts by forming outgrowths, the capsule thickens and becomes inflamed: the joint becomes stiff and painful, and the pain makes the dog use it less, which wastes the muscles that held it. It is a circle, and the whole point of treatment is to break it.

In people, arthritis is often a matter of wear with age. In dogs, it is almost always secondary: it sets in on a joint that has an initial defect or has been damaged, hip or elbow dysplasia, a torn cruciate ligament in the knee, a luxating kneecap, an old fracture. That is why it can start in a young dog, and why it so often affects breeds predisposed to these defects.

It is the joint disease most often diagnosed in veterinary medicine. In a British study of the records of 455,557 dogs seen by their vet in 2013, 2.5% had been diagnosed with osteoarthritis during the year, about 200,000 dogs in the UK; the associated factors were breed (labrador and golden retriever at the top), higher body weight, being over 8 years old, neutering, and being insured (these dogs are probably examined more often). The authors estimate that osteoarthritis occupies on average 11.4% of the life of an affected dog (Anderson, O'Neill, Brodbelt et al., Scientific Reports, 2018). Those 2.5% are the diagnosed dogs: many others live with it without anyone noticing.

Signs and symptoms of arthritis in dogs: the ones you see, and the ones you do not

Do not count on complaints. "Dogs cope and often give off very few overt signs suggesting difficulty or discomfort", writes the British veterinary organisation Canine Arthritis Management: what you see instead are small changes in behaviour, hesitations, avoidance. A dog in pain keeps walking to its bowl or to you, even if every step on the tiles costs it.

• Getting up: it takes a while to get up, stretches for a long time, takes its first steps stiffly, then "warms up" as it walks. This is the most typical sign.
• On walks: it lags behind, stops, asks to go home earlier, starts limping after exercise or the day after a big outing, hesitates at a ditch.
• Climbing: it hesitates before jumping into the car or onto the sofa, tries several times, climbs the stairs slowly or comes down them too fast, which is a sign of lack of control, not of ease.
• At home: it slips on tiles or wooden floors, splays its legs, avoids certain rooms, sits crookedly, lies down in stages.
• Its body: it licks a joint, its thighs waste (muscle loss at the back), it sleeps more and circles for a long time before lying down.
• Its mood: it growls when a hip is touched, plays less with other dogs, becomes less patient with children.

Vets have questionnaires for owners to fill in to put all this on record. The most widely used in Europe, the LOAD questionnaire ("Liverpool Osteoarthritis in Dogs"), has been validated on 222 dogs with osteoarthritis: its scores track the measurements of the force platform that records the weight borne on each leg (Walton et al., PLoS One, 2013). In other words, what you see at home is a real measurement: note it down, film it, and bring it to the consultation.

How to know if my dog has arthritis: the diagnosis

The diagnosis rests on three things: your account (since when, at what time of day, after what exertion), the orthopaedic examination, in which the vet feels and flexes each joint looking for pain, stiffness, crackling or thickening, and X-rays, which show the bony outgrowths and the original defect, dysplasia or an old rupture. Beware of one trap: X-rays and pain do not always go together. A dog can have impressive images and little pain, or the reverse. It is the pain and the everyday difficulty that decide the treatment, not the X-ray alone.

Blood and urine tests often complete the consultation, before prescribing a long-term anti-inflammatory, to check the kidneys and the liver.

How to relieve a dog's arthritis: the four pillars with proven results

Arthritis cannot be cured: cartilage does not grow back. But you can reduce pain, keep the muscles and slow the progression, and it works all the better when several levers are combined. Vets speak of "multimodal" management; in practice, it comes down to four pillars.

1. Weight: the most effective treatment, and the cheapest

Every extra kilo weighs on painful joints, and fat itself sustains inflammation. In a trial of 14 obese dogs with osteoarthritis put on a diet for 16 weeks, lameness decreased clearly from 6.1% of weight lost, and force-platform measurements improved from 8.85%; the authors conclude that a "noticeable improvement" is possible after modest weight loss (Marshall, Hazewinkel et al., 2010). For a 35 kg labrador, that is a little over 2 kilos.

And prevention starts early: in a famous study, 48 labradors were followed in pairs throughout their lives, one of the two receiving 25% less food from 8 weeks of age. The restricted dogs stayed leaner, lived longer on median, and the signs of chronic disease appeared later in them (Kealy et al., JAVMA, 2002). A dog whose waist you can see and whose ribs you can feel without pressing has a real head start.

In practice: weigh it once a month, ask the vet for its ideal weight, reduce the ration in steps, count treats in the ration, and replace some rewards with crunchy vegetable pieces or kibble taken from its daily share.

2. Movement: little, but every day

Complete rest is a false good idea: "if you don't use it, you will lose it", sums up Canine Arthritis Management. An arthritic dog that stops moving loses muscle, and its joints, less supported, hurt more. What works is regular, moderate exercise:

• several short outings a day rather than one long one, at the same pace every day, and no "big Sunday walk" after a week of rest;
• on the leash on painful days, on soft, flat ground (grass, paths), avoiding steep slopes, stairs and downhill tarmac;
• no repeated ball throwing, sharp turns or jumps: it is the impacts and twists that hurt;
• swimming and walking in water, where body weight is supported, are ideal when possible; hydrotherapy and veterinary physiotherapy rebuild muscle without damage;
• a five-minute warm-up at a walk before letting it run, and a cool-down.

The right yardstick: the outing is too long if the dog limps or is stiffer in the evening or the next day.

3. Veterinary pain relief

Pain, for its part, is treated. Medicines are the vet's domain, chosen according to age, other diseases and blood tests; here is what exists, and what we know about it:

Sources: Corral et al. 2021 (anti-NGF antibody); Roush et al. 2010 (omega-3); European Medicines Agency. The percentages are those of the trials, not promises for any given dog.

4. The home: removing slips and jumps

This is the pillar people forget, and the one where you can do everything yourself. Canine Arthritis Management devotes a whole guide to it, and the starting point is simple: a dog's pads are made for rough ground, hard and not grippy; on a slippery floor, tiles, sealed wood or laminate, "add some overlying fur and they become like slippery socks". Every slip forces a stiff joint beyond its range; repeated, slips sustain the pain. Room by room:

• Floors: non-slip runner rugs along its usual routes (its bed, its bowl, the garden door), anti-slip strips on thresholds, and non-slip socks for dogs that still slip. Trim the hair between the pads and keep the nails short: a nail that is too long changes how the foot lands.
• Stairs: the hardest thing for an arthritic dog. A stair gate when possible; otherwise, carry a small dog, or help a large one with a harness with a handle or a rear support harness, without ever putting yourself at risk.
• The sofa and the bed: jumps, especially coming down, are impacts that arthritic joints hate. Offer an equally pleasant bed on the floor, or install a ramp or steps.
• The car: a ramp for the boot, or lift the hindquarters with the support harness; no more jumping out of an SUV boot.
• The bed: a mattress that is both supportive and soft, thick enough that the hips do not touch the floor, big enough to stretch out, with a low entry and no rim to step over, warm and out of draughts. A dog that circles for a long time without settling, or keeps getting up, may have poorly controlled pain, notes Canine Arthritis Management: its sleep is a good indicator.
• Bowls: a dog with hip arthritis compensates with its neck and shoulders; raising the bowl to elbow height helps it eat without leaning. But in large, deep-chested dogs, raised feeders are associated with a higher risk of bloat: for them, Canine Arthritis Management advises raising only the water and serving the kibble in a slow-feeder bowl on the floor. Ask the vet.
• The garden: loose paving, wet decking, steep slopes, poorly lit corners; a ramp instead of steps if needed.

Arthritis flare-up: what to do when it is in a lot of pain

An arthritic dog has good days and bad days, and sometimes a real flare: it limps badly, refuses to get up, whimpers as it lies down, pants at rest, trembles. In that case:

1. Call the vet the same day: a flare-up can be treated, and sudden lameness can be something other than arthritis (a torn ligament, a fracture, a slipped disc).
2. Relative rest for a few days: short outings on the leash for toileting, no stairs, no jumping, no play.
3. A comfortable bed in the warm, with water and its bowl within reach.
4. No human medicine, no "leftover" anti-inflammatory from another animal.
5. Then a gradual return to exercise, and a check-in with the vet on the long-term treatment: frequent flare-ups mean the pain is not well enough controlled.

Winter, cold and damp

Many owners find their dog stiffer in winter, in cold, damp weather, whether because of the cold itself or reduced activity. What helps: a warm bed, away from tiles and draughts, a self-heating mat that reflects its own warmth, outings at the least cold times of day, careful drying on return, and for a short-coated, thin or old dog, a coat: our guide dog coat says which dogs need one and from what temperature. And it is the season of slippery floors and snow, when falls need extra attention.

How long can a dog live with arthritis?

A long time. Arthritis is not a fatal disease in itself: it is a chronic pain that accompanies the dog for years, on average more than a tenth of its life according to the British study. What matters, more than life expectancy, is quality of life: a well-treated dog, at the right weight, in an adapted home, can keep good years of walks, calm games and naps in the sun.

The question of euthanasia sometimes arises, at an advanced stage, when the pain is no longer controlled despite treatment, the dog can no longer get up on its own, no longer sleeps, no longer eats with appetite and has lost what made its days. It is decided with the vet, on the dog's condition and not on an X-ray, and there is no hurry as long as there are solutions left to try: an adjusted treatment, the monthly injection, physiotherapy and a few adaptations often change everything.

Preventing arthritis from puppyhood

• A healthy weight throughout life, from puppyhood: it is the measure with the most effect, as the study of restricted labradors shows.
• Controlled growth for large breeds: a food suited to large-breed puppies, without added calcium supplements, and no rapid weight gain.
• Exercise suited to a puppy: no running alongside a bike or long jumping sessions before growth is complete, but free, varied play.
• Dysplasia screening in breeding dogs of at-risk breeds, and choosing a breeder who does it.
• Prompt consultation for lameness: a torn cruciate ligament or a luxating kneecap operated on in time leaves a less damaged joint.
