Understanding Osteoarthritis in Dogs: Causes, Symptoms & Treatments

Kerry Chrapliwy • January 30, 2021

Just like humans, your four-legged friend relies on their joints for a lot of things. Moving, walking, running, playing – many of the behaviors happy dogs exhibit depend on healthy joints. While it’s common, osteoarthritis in dogs can also significantly affect your pet’s quality of life. Fortunately, there are plenty of treatments for dogs with arthritis to help manage pain, inflammation, and damage. Let’s take a closer look.


What is Osteoarthritis?

Osteoarthritis (OA), or arthritis, is a chronic, progressive joint disease. It’s a top cause of joint pain in dogs. The condition causes the gradual loss of joint cartilage, which leads to changes in bones, pain, and inflammation. 

In healthy joints, cartilage is the cushion that allows joints to move smoothly through their full range of motion. However, in cases of OA, this cartilage cushion starts to break down. This can happen for all kinds of reasons, from injury to age to repetitive stress and disease. 

Osteoarthritis commonly affects dogs as they age, but it can occur in young dogs, too. It’s especially likely to affect dogs who have other contributing factors, like obesity or other orthopedic conditions.

Unfortunately, there is no cure for OA in dogs. However, there are steps you can take to slow its progression. 


Symptoms of Osteoarthritis in Dogs

We know that OA commonly affects dogs and that early intervention is one of the best ways to slow its progression. That begs an important question, then: “How do I know if my dog has arthritis?” 

Our furry friends may not be able to speak to us, but they can clue us into how they’re feeling through body language. Signs of arthritis in humans are fairly similar to those of osteoarthritis in dogs; symptoms include:

  • Pain
  • Stiffness
  • Lameness or a change in gait
  • Weight gain
  • Sudden changes in behavior, like irritability or aggression
  • Decrease in activity or reluctance to exercise, walk, or run
  • Difficulty getting up from lying down, navigating stairs, or jumping on furniture
  • Loss of muscle mass or muscle wasting over the limbs and spine
  • Difficulty posturing to urinate or defecate, which may lead to having accidents in the house


Causes of Osteoarthritis in Dogs

In many cases, there’s more than one cause of osteoarthritis in dogs. Sometimes, there may be no obvious underlying cause at all. Still, there are a few factors that typically contribute to the condition’s development:

  • Orthopedic diseases like cranial cruciate ligament tears, patella luxations, hip and elbow dysplasia, or previous fractures can lead to OA by causing repeated injuries to joint cartilage. Repetitive high-impact activities can also cause damage. 
  • Obesity also plays a significant role in the development of OA because it places extra force on the joints.


Other risk factors for arthritis in dogs include:

  • Age
  • Breed: large or giant breeds are more likely to have conditions like hip dysplasia and OA
  • Genetics
  • Improper nutrition
  • Infections that affect the joints, such as Lyme disease

Managing Osteoarthritis in Dogs: Treatment Options

Depending on its underlying cause, dog arthritis treatment usually involves a combination of lifestyle changes, pain management, physical rehab, and joint support. In severe cases, surgery may be necessary.


Lifestyle Changes

Helping pets shed extra pounds and maintain a healthy weight can go a long way in treating osteoarthritis. Sticking to low-impact activities for exercise and using ramps to get on and off furniture also helps. 


Professional Physical Rehabilitation

Using an underwater treadmill, swimming, balance, and range of motion exercises can help ease pain and keep the joints from getting too stiff. 


Pain Management

Options like NSAIDs (nonsteroidal anti-inflammatory drugs) support joint pain relief for dogs. Medications like gabapentin can also be used in combination with NSAIDs.


Joint Support

Using supplements like fish oil, undenatured type II collagen, and Adequan can help promote optimal joint health for your pet.


Joint Surgery for Dogs

While surgery is rarely needed for joint pain treatment for dogs, it’s sometimes required. It’s most commonly recommended in cases with a clear underlying cause of OA, like hip or elbow dysplasia. 


How will my vet diagnose osteoarthritis?

If you believe your dog may have arthritis, the first step to take is visiting your veterinarian. Your vet will diagnose OA using one or more of the following:

  • Physical Exam: During a physical, your vet can observe your dog’s posture and gait. They can also feel for any abnormalities in the joints or signs of pain.
  • X-Rays: Sometimes, X-rays may be necessary to fully assess the joints and diagnose underlying orthopedic conditions.
  • Advanced Imaging: In some cases referral to a specialty hospital such as Violet Crown Veterinary Specialists may be recommended for advanced imaging like a CT. These tests help your vet accurately evaluate the state of your dog’s cartilage, joints, and soft tissues surrounding the bone, which don’t show up on an X-ray.

If you’re located in or near Austin, TX, you can count on Violet Crown Veterinary Specialists for comprehensive osteoarthritis care. 

Our diagnostic imaging deparment is equipped with all of the resources necessary to diagnose OA and related conditions, including cranial cruciate ligament tears, patella luxation, elbow and hip dysplasia. Plus, our team of specialists can help you navigate the treatment process, whether it involves simple lifestyle changes or something more involved, like surgery.

Keeping your cat’s litter box clean is essential for maintaining its long-term health. Even after meticulously scooping the urine clumps, replacing the litter once a week, and scrubbing every inch of the litter box every couple of weeks, your cat may still experience urinary issues. Urinary obstruction in cats is one of the more serious ailments affecting the urethra and requires urgent medical attention. What is Urinary Obstruction? Urinary obstruction in cats describes situations involving a partial or full blockage of the urethra, which is the tube that carries urine from the bladder to the cat’s external opening. You might hear your veterinarian call it a urethral blockage or urethral obstruction, and it’s one of the most common reasons for cats to see their vets. A urinary obstruction may be referred to as FLUTD, or feline lower urinary tract disease. You may also hear the term FIC, short for feline interstitial cystitis, which refers to inflammation of the bladder. Urinary obstructions are most common in young castrated male cats, but can occur in older pets and intact males as well. FIC is also much more common in cats younger than 10. Risks of Urinary Obstructions Urinating is a vital function for almost all creatures, as it eliminates waste and maintains appropriate levels of bodily fluids. Retaining urine can result in: Bladder tear (rupture) due to increased pressure Renal (kidney) damage or failure Heart problems due to electrolyte imbalances What Causes Urinary Obstructions in Cats? The inflammation that occurs with FIC is a common cause of urinary obstructions in cats. Two other ailments commonly associated with urinary obstructions are uroliths (bladder stones that can travel to the urethra) and urethral plugs, which consist of bodily crystals and mucus. Cancer is a rare cause of urinary obstructions. Preventing Urinary Obstruction Maintaining your cat’s general health, which involves regular vet check-ups, can reduce the chances of urinary obstructions. Ensuring your felines have access to enough water and food is also essential, as is helping them stay at healthy weights. Male cats are prone to urinary obstructions and other FLUTDs because their urethra is narrower and longer than those of female cats. Some cats who experience frequent urinary obstructions may benefit from a procedure called a perineal urethrostomy (PU), which widens the urethral opening. Treating Urinary Obstruction: When to See an Emergency Vet It’s a good idea to take your cat to a vet as soon as possible if you notice signs of urinary obstruction, as serious health problems can crop up within 12 hours or less. Untreated urinary obstructions can cause death in cats within 24 hours, so time is of the essence. Common symptoms of urinary obstructions in cats include: Frequent urination (more than four times per day) Weak urinary flow Urinating only a few drops at a time (or nothing at all) Bloody or cloudy urine Vocalizing or crying out while urinating Straining while urinating Urinating outside of the litter box Vomiting Diarrhea Lethargy Decreased appetite Excessive licking of their genitals If you suspect your cat is exhibiting these symptoms but aren’t sure, we strongly recommend erring on the side of caution and bringing them to a vet as soon as possible. Depending on the location of the litter box, it may be difficult to tell whether your cat is having trouble peeing or not urinating at all. Your vet may insert a catheter to drain the backed-up urine, and your cat may need to take medications for a few days.
