Arthritis is one of the most common chronic conditions affecting dogs and cats, especially as they age. Most of the senior dogs and cats we see have some degree of arthritis. Many pet owners assume slowing down is simply a normal part of getting older, but in many cases, pain and joint disease are contributing factors. The good news is that arthritis can often be managed successfully with a combination of medical care, lifestyle changes, rehabilitation, and supportive therapies.
Early recognition and treatment can significantly improve comfort, mobility, and quality of life for pets.
What Is Arthritis?
Arthritis, also called osteoarthritis or degenerative joint disease, occurs when the cartilage within a joint begins to wear down over time. Cartilage normally acts as a cushion between bones. As it deteriorates, inflammation develops within the joint, leading to pain, stiffness, and decreased mobility.
Arthritis can affect any joint, but it is commonly seen in:
- Hips
- Knees
- Elbows
- Shoulders
- Spine
While arthritis is more common in senior pets, younger animals can also develop joint disease due to:
- Previous injuries
- Cruciate ligament tears
- Hip or elbow dysplasia
- Obesity
- Congenital orthopedic conditions
- Repetitive athletic stress
Signs of Arthritis in Dogs
Dogs often show gradual changes that may initially seem subtle. Signs can include:
- Difficulty getting up after resting
- Slowing down on walks
- Reluctance to jump, climb stairs, or play
- Limping or stiffness, especially after activity
- Sleeping more than usual
- Muscle loss in the hind limbs
- Irritability or changes in behavior
- Hesitation getting into cars or onto furniture
- Licking at joints
Some dogs become less interactive or appear “grumpy” because chronic pain affects mood and behavior.
Signs of Arthritis in Cats
Cats are especially skilled at hiding pain, so arthritis is frequently underdiagnosed. Instead of obvious limping, cats may show behavioral changes such as:
- Jumping less often or not reaching previous heights
- Difficulty getting into the litter box
- Sleeping more
- Reduced grooming, leading to a matted coat
- Avoiding stairs
- Increased hiding
- Irritability when touched
- Accidents outside the litter box
- Reduced activity or playfulness
Owners often interpret these changes as “slowing down,” but many arthritic cats are experiencing significant discomfort.
How Arthritis Is Diagnosed
Diagnosis typically begins with a thorough physical examination. During the exam, your veterinarian may identify:
- Joint thickening
- Decreased range of motion
- Pain with manipulation
- Muscle loss
- Abnormal gait or posture
Radiographs (x-rays) are commonly recommended to evaluate the joints and look for:
- Bone remodeling
- Joint narrowing
- Arthritis-related bone changes
- Previous injuries
In some cases, additional diagnostics such as bloodwork may be recommended before starting long-term medications to ensure safe treatment planning.
Medical Treatment Options
There is no cure for arthritis, but many treatment options can help reduce pain and inflammation while improving mobility.
Anti-Inflammatory Medications
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most common and effective arthritis treatments in dogs. These medications help reduce inflammation and improve comfort.
Because NSAIDs can affect the liver, kidneys, and gastrointestinal tract, regular monitoring and veterinary supervision are important.
Cats have fewer safe long-term medication options than dogs, but carefully selected therapies can still provide substantial relief.
Pain Medications
Additional pain medications may be used alongside anti-inflammatories, including medications that target chronic nerve-related pain pathways.
Combination therapy is often more effective than relying on a single medication alone.
Injectable Arthritis Therapies
Several newer injectable medications are now available for dogs and cats with osteoarthritis pain. These therapies can help decrease pain signals and improve mobility for weeks at a time.
Many pets that struggle with oral medications tolerate injections very well.
Joint Supplements
Supplements may help support joint health and are often most effective when started early.
Some options with scientific research include:
- Glucosamine and chondroitin
- Omega-3 fatty acids (fish oil)
- Green-lipped mussel
- UC-II collagen products
- Injectable joint support products
Not all supplements are created equally. Veterinary-recommended products are typically preferred because they undergo more rigorous quality control and testing.
Weight Management: One of the Most Important Treatments
Excess weight places significant strain on arthritic joints. Even modest weight loss can dramatically improve comfort and mobility.
For many pets, weight management is one of the most impactful arthritis treatments available.
Your veterinary team may recommend:
- Prescription weight-loss diets
- Calorie adjustments
- Low-impact exercise plans
- Regular weight monitoring
Physical Therapy and Rehabilitation
Physical rehabilitation can play a major role in improving strength, flexibility, and comfort. While we do not offer some of these therapies at Friendship Animal Hospital, we will be happy to help you with a referral to a local facility that does.
Therapies may include:
- Underwater treadmill therapy
- Therapeutic exercises
- Stretching and range-of-motion exercises
- Balance and strengthening work
- Massage therapy
Rehabilitation is especially helpful after orthopedic surgery or injury, but can also greatly benefit senior pets with chronic arthritis.
Alternative and Integrative Therapies
Many pets benefit from integrative approaches used alongside traditional medical therapy.
Acupuncture
Veterinary acupuncture may help reduce pain, improve circulation, and support mobility in some pets with chronic arthritis.
Laser Therapy
Therapeutic laser treatments are commonly used to decrease inflammation and discomfort while promoting healing within tissues.
Many pets tolerate laser therapy very well, and treatments are non-invasive.
Environmental Modifications
Simple home changes can make a significant difference for arthritic pets:
- Orthopedic bedding
- Non-slip rugs or flooring
- Pet ramps or stairs
- Elevated food and water bowls
- Low-entry litter boxes for cats
- Keeping nails trimmed for traction
Why Early Treatment Matters
Arthritis is progressive, meaning it typically worsens over time if left unmanaged. Early intervention helps preserve mobility, reduce chronic pain, and maintain quality of life.
Many pets respond best to a multimodal approach — combining medications, supplements, weight management, rehabilitation, and supportive care tailored to the individual pet.
When Should You Schedule an Evaluation?
If your dog or cat is showing any signs of slowing down, stiffness, decreased activity, or behavioral changes, it may be time for an arthritis evaluation.
Pets do not have to “just live with” pain as they age. With proper management, many arthritic pets can continue enjoying walks, playtime, family interaction, and a comfortable daily life for years to come.
