Dog Swollen Joints: Causes and Care

When your dog starts limping or struggling to move, it can be heartbreaking to watch. Swollen joints in dogs are a common issue that can cause discomfort and limit mobility. It often signals an underlying problem that requires attention. Below, we’ll help you understand the causes of dog swollen joints and know when to seek veterinary care to help keep your pet comfortable and active.

What Causes Dog Swollen Joints?

Swollen joints in dogs can occur for various reasons, ranging from minor injuries to serious medical conditions. Identifying the cause is the first step in providing proper care.

Arthritis and Degenerative Joint Disease

One of the most frequent causes of dog swollen joints is arthritis, particularly osteoarthritis. This degenerative condition leads to the gradual breakdown of cartilage, causing inflammation and pain. Arthritis is more common in senior dogs but can affect younger pets, especially those with genetic predispositions. Other factors, such as obesity and previous joint injuries, can contribute to the development of arthritis in dogs.

Injuries and Trauma

Dogs are naturally active, and injuries can happen during play, exercise, or accidents. A fall, awkward landing, or collision with an object can lead to ligament injuries or fractures resulting in swelling. One of the most common injuries leading to joint swelling is a torn cranial cruciate ligament (CCL), which affects the knee joint and often requires surgical intervention.

Infections and Immune Disorders

Bacterial or fungal infections can cause inflammation in a dog’s joints, leading to swelling and pain. Conditions like Lyme disease, which is transmitted by ticks, can cause joint inflammation and stiffness. Additionally, autoimmune diseases such as immune-mediated polyarthritis (IMPA) can trigger the body’s immune system to attack the joints, leading to persistent swelling and discomfort.

Cancer and Tumors

In some cases, swollen joints in dogs may be linked to bone or joint tumors. Osteosarcoma, a type of bone cancer, can cause localized swelling around the affected joint. While less common than other causes, cancer-related joint swelling requires immediate veterinary evaluation to determine the best course of action.

Recognizing Symptoms of Swollen Joints in Dogs

Dogs cannot communicate their pain, so pet owners need to recognize signs of swollen joints. Early detection can lead to quicker intervention and better outcomes.

• Limping or favoring a leg – Dogs with joint pain often avoid putting weight on the affected limb.
• Stiffness or difficulty moving – A dog with swollen joints may have trouble standing, climbing stairs, or jumping.
• Visible swelling around the joint – Swelling may be subtle or pronounced, depending on the cause.
• Pain when touched – Dogs may yelp, whimper, or pull away when their joints are touched.
• Lethargy or reluctance to play – If moving causes discomfort, dogs may become less active.
• Licking or chewing the affected area – Persistent licking can indicate discomfort or pain in a swollen joint.

If you notice these symptoms in your dog, consult your veterinarian promptly. Pinnacle Veterinary Specialists can assess your pet’s condition and recommend appropriate care. Call (610) 477-8797 to schedule an appointment.

Effective Veterinary Care for Dog Swollen Joints

The team at Pinnacle Veterinary Specialists will evaluate your dog’s swollen joints through a thorough physical examination, medical history review, and diagnostic tests.

Diagnostic Procedures

• Physical examination – We will check for swelling, pain, and range of motion limitations.
• X-rays and imaging – Radiographs or advanced imaging (CT or MRI scans) can identify fractures, arthritis, or tumors.
• Joint fluid analysis – A sample of joint fluid can be tested for infections, inflammation, or immune-related conditions.
• Blood tests – Lab tests can detect underlying infections, tick-borne diseases, or autoimmune disorders.

Treatment Strategies

Treatment depends on the underlying cause of joint swelling. Common approaches include:

• Pain management – Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation.
• Joint supplements – Glucosamine and chondroitin may support joint health and slow degeneration.
• Antibiotics or antifungal medications – If an infection is present, appropriate medications will be prescribed.
• Surgery – Severe injuries, ligament tears, or joint tumors may require surgical intervention.
• Weight management and exercise modifications – Maintaining a healthy weight and adjusting activity levels can alleviate joint stress.

We will develop a treatment plan tailored to your dog’s specific needs. If your dog has swollen joints and needs expert care, call Pinnacle Veterinary Specialists at (610) 477-8797.

When to Seek Emergency Veterinary Care

Some cases of dog swollen joints require immediate attention. Seek emergency care if your dog experiences:

• Sudden and severe joint swelling
• Inability to bear weight on a limb
• Extreme pain or distress
• Signs of infection (fever, lethargy, loss of appetite)
• Rapidly worsening symptoms

Delaying care could lead to further complications. If your dog’s joint swelling appears serious, contact Pinnacle Veterinary Specialists right away.

Helping Your Dog Stay Active and Comfortable

While some causes of dog swollen joints require long-term management, proactive care can improve your dog’s quality of life. Providing a comfortable resting area, maintaining a balanced diet, and engaging in appropriate low-impact exercise can support joint health. Regular veterinary check-ups ensure that any developing issues are addressed early. If your dog is struggling with swollen joints, professional veterinary care is the best way to identify and manage the problem.
