Prevention and Treatment
Since osteoarthritis in dogs cannot be completely cured, prevention and early intervention are paramount. Helping your dog maintain a healthy weight from the time he is a puppy is a critical deterrent of osteoarthritis. Another precautionary measure is to leash train your pup and keep him leashed or in a fenced-in yard to prevent traumatic encounters with cars. If you choose to buy a dog from a breeder, choose someone who evaluates both parent dogs for developmental orthopedic problems like hip dysplasia.
Despite a pet parent's best efforts, osteoarthritis in dogs is often unavoidable. Once your vet confirms the condition with an exam, radiographs, magnetic resonance imaging (MRI), or CT scan, they'll discuss your pup's range of treatment options.
Your vet may prescribe a nonsteroidal anti-inflammatory drug (NSAID) or other medication to relieve the pain and symptoms of osteoarthritis. They may also suggest a joint supplement like glucosamine or chondroitin sulfate, two of the components of cartilage. Omega-3 fatty acids are another supplement given to dogs with osteoarthritis due to their anti-inflammatory benefits.
Although supplements are often available over the counter, you should never give your dog anything without asking your vet first. All medications and supplements have the potential for side effects and must be given under the close supervision of a vet.
Other non-traditional yet potentially helpful treatments include acupuncture, massage, and cold laser therapy. Rehabilitation facilities that offer these services may also provide underwater treadmill exercise (or hydrotherapy), which can be a wonderful low-impact activity for dogs with joint degeneration.

Other Ways to Help Your Pup
Nutrition can play a role in managing osteoarthritis in dogs. Your vet may initially recommend a therapeutic weight loss food or one that is shown to help in preserving joint health. Some of these formulas contain supplements like glucosamine in a tastier and easier-to-administer form.
In more severe cases, surgery may be an available option. Total hip replacement has been very useful in restoring function to otherwise disabled dogs or dogs with developmental conditions.
Besides the options prescribed by your vet, pet parents can take measures at home to maximize their dog's comfort. Providing padded beds, ramps up to cars and steps and no-skid rugs on slippery floors will make a significant difference. You should also block off any stairs to prevent your pet slipping and falling and supervise him when he goes outside.
Although it is disheartening to see a beloved companion slowing down, there are many ways to ensure his happiness, quality of life and continued role in your family. Keeping an eye out for the signs of arthritis in dogs can help your pet stay in good health for as long as possible.
