Does your dog seem a little slower lately? Maybe they’re not as keen to jump onto the couch, or they take a bit longer to get going in the mornings. It’s easy to chalk it up to getting older, but for many dogs, what looks like normal ageing is actually arthritis, and it’s happening much earlier than most pet owners realise.
Arthritis in dogs is a common condition, affecting one in five adult dogs, and it is a major cause of chronic pain in older dogs. Here in Melbourne and across Australia, vets are seeing more cases earlier, which means there’s never been a better time to understand what you’re actually looking at.
This guide walks you through the subtle symptoms of arthritis in dogs, why they’re so easy to miss, and what treatment options are available to help your dog live comfortably.
What Is Canine Arthritis, and Why Does It Happen?
Arthritis is a term that covers a range of degenerative joint conditions. The most common form in dogs is osteoarthritis, also called degenerative joint disease, where the cartilage cushioning the joints gradually breaks down. When that cartilage wears away, bones rub against each other, which causes inflammation, pain, and reduced range of motion.
Unlike in humans, dogs almost never develop arthritis purely from old age. Dogs almost always develop what’s called “secondary arthritis,” meaning there is an underlying abnormality of the joint, such as hip or elbow dysplasia, a previous fracture, abnormal limb alignment, or joint instability from a ligament tear. So by the time your dog is showing signs, something has often been quietly developing in those joints for years.
Common causes include:
- Hip or elbow dysplasia (especially in large breeds)
- Previous ligament injuries, including CCL tears
- Obesity, which places an excess load on every joint
- Repetitive high-impact activity over a dog’s lifetime
- Breed predisposition, particularly in larger dogs
German Shepherds, for example, face a three times higher chance of hip dysplasia and 1.5 times higher risk of arthritis than the average dog, while Labradors are about 1.6 times more likely to develop lameness and arthritis, driven by genetics and weight.
Early Signs of Arthritis in Dogs That Owners Often Miss
This is where things get tricky. Dogs are instinctively good at hiding pain, which means the early signs of arthritis in dogs tend to look like everyday slowing down. Many owners don’t notice anything is wrong until the condition has progressed significantly.
Here are the signs to watch for:
Stiffness After Rest
One of the earliest and most common arthritis symptoms is stiffness when your dog first gets up after sleeping or lying down. You might notice your dog is walking slowly for the first few minutes, then seems to loosen up. That improvement can make owners think everything is fine when in reality, the joints need time to warm up before they move comfortably.
Reluctance to Jump or Climb
If your dog used to leap onto the couch or into the car without a second thought and now hesitates, that’s a sign that your dog may be experiencing joint pain. Watch for a dog that puts their front legs up first and then struggles to bring the hind legs up, or that refuses stairs they once climbed without issue.
A Subtle Limp or Favouring One Leg
Lameness doesn’t always look dramatic. You might notice your dog shifting their weight off one leg, or favouring front legs on one side. Sometimes the limp is only visible after exercise or first thing in the morning, which makes it easy to dismiss. Even a mild, intermittent limp deserves a vet check.
Behavioural Changes
A dog in pain often becomes irritable, withdrawn, or less interested in play and interaction. If your normally sociable dog is snapping when touched in certain areas, reluctant to follow you around the house, or has lost interest in play they used to love, pain could be the reason. These changes in behaviour are worth taking seriously.
Licking or Chewing at Joints
Dogs will often lick at a sore joint repeatedly. If you notice your dog frequently licking at their elbow, hip, or hind legs, arthritis may be causing discomfort in that area.
Less Active Than Usual
A dog that used to be happy on long walks but now lags, sits down mid-walk, or seems exhausted after short exercise may be managing joint pain rather than simply getting lazy.
Which Dogs Are at Risk?
Arthritis occurs in around 90% of older dogs and approximately 20% of middle-aged dogs. But risk doesn’t start at old age. While 80% of dogs will show signs of arthritis by age 8, around 20% of dogs show signs as early as the age of one year.
The following factors increase a dog’s likelihood of developing arthritis:
|
Risk Factor |
Why It Matters |
| Large or giant breed | More weight is placed on joints; a higher rate of dysplasia |
| Hip or elbow dysplasia | Abnormal joint development accelerates cartilage breakdown |
| Obesity | Every extra kilogram multiplies the pressure on joints |
| Previous injuries | A damaged ligament or fracture increases joint instability |
| High-impact exercise history | Repetitive strain on joints over time |
| Age over 7 years | Risk increases significantly in senior dogs |
According to PetSure data from 2024, osteoarthritis was the seventh most common condition claimed for in dogs overall in Australia, and the most common claim for dogs over eight years old.
For Melbourne dog owners, that’s a significant figure. With so many active dogs living in homes across Melbourne’s suburbs, and spending years walking, running, and playing, joint wear accumulates faster than many owners expect.
Symptoms of Osteoarthritis: What Vets Look For
When you bring your dog in, a veterinarian will look beyond what you can see at home. A thorough physical examination assesses how the joint moves, where pain is located, and how much swelling or muscle wasting is present.
From there, a radiograph (x-ray) is usually the key diagnostic tool. A radiograph can show:
- Narrowing of the joint space
- Bone spurs (osteophytes) are forming around the joint
- Changes in cartilage density
- Signs of degenerative joint disease at specific sites
At Keysborough Veterinary Practice, the team offers both X-rays and ultrasounds on site, which means your dog can be assessed and diagnosed in a single visit. Early imaging can catch arthritis before it becomes severe, giving you a much better window for managing it effectively.
Treatment for Arthritis in Dogs: What Are the Options?
There’s no cure for arthritis, but there are many ways to slow its progression and keep your dog comfortable. The goal of any good arthritis management plan is to reduce pain and inflammation, preserve joint function, and protect your dog’s best quality of life for as long as possible.
Common treatment options include:
Pain Relief Medication and NSAIDs
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used tools for managing arthritis pain and inflammation in dogs. They help reduce swelling in the joint and provide meaningful pain relief. These must always be prescribed by a veterinarian, as the wrong dose or wrong product can cause serious harm.
Joint Supplements
Omega-3 fatty acids, glucosamine, and chondroitin are frequently recommended to support cartilage health and slow joint degeneration. They work best as part of a broader management plan, rather than as a standalone treatment.
Weight Management
This one is often underestimated. Reducing a dog’s weight takes significant pressure off arthritic joints, and can make a noticeable difference to comfort and mobility even without medication. Your vet can help you develop a weight management plan that suits your dog’s breed, age, and health status.
Physiotherapy and Hydrotherapy
Controlled exercise, swimming, and targeted physiotherapy can maintain muscle mass around arthritic joints, which provides better support and reduces pain. Melbourne has a growing number of canine rehabilitation specialists that your vet can refer you to.
Surgical Options
For dogs with hip or elbow dysplasia or severe joint damage, surgical intervention may be recommended. This is assessed on a case-by-case basis and is more common in younger dogs, where corrective surgery can prevent further joint deterioration.
The right approach depends on the dog’s age, weight, which joints are affected, and how far the arthritis has progressed. That’s why an accurate diagnosis matters so much. A management plan built on guesswork won’t give your dog the help they need.
How Arthritis Can Affect Dogs and Cats Differently
While this article focuses on dogs, it’s worth noting that arthritis also affects cats, though they show it differently. Dogs and cats both experience degenerative joint disease, but cats tend to become quieter and less active rather than showing obvious lameness. If you have both dogs and cats at home, Melbourne pet owners should watch both for subtle shifts in behaviour and mobility.
When to See a Veterinarian
If you notice any of the signs above, book a check-up. You don’t need to wait until your dog is visibly limping or crying out. In fact, the earlier arthritis is identified, the more effective the management plan tends to be.
A good rule of thumb: if your senior dog is slowing down and you’re not sure why, it’s worth getting them assessed. Don’t assume it’s just ageing. Age itself doesn’t cause arthritis, but it does increase the likelihood that something is quietly happening in those joints.
The veterinary team at Keysborough Veterinary Practice in Melbourne can assess your dog’s joint health through physical examination, on-site imaging, and a tailored management plan. Early detection gives your dog the best possible chance of remaining comfortable and active for years to come.
