Injections for Dogs with Arthritis: A Guide to Joint Fluid Replacement & Subcutaneous Treatments
As pet owners, we spend a lot of our time trying to do right by our four-legged friends. However, as our dogs age, the likelihood of them developing certain diseases, such as arthritis, increases.
Just like in humans, arthritis in dogs can cause joint pain, stiffness, and reduced mobility. Therefore, it’s essential to seek the best, most effective treatments possible to improve their quality of life.
In this blog post, we will delve into the benefits of injections for dogs with arthritis, focusing on two main types of arthritis injection treatments: joint fluid replacement and subcutaneous injections.
These offer good results in managing arthritis symptoms and improving joint health, allowing our dogs to enjoy happier and more active lives. Read on to learn more about injections for dogs with arthritis!
Symptoms of Arthritis in Dogs
Canine osteoarthritis can be a silent struggle, as our dogs can’t always communicate their pain. However, there are signs to watch for that may indicate the progression of arthritis. Look out for difficulty getting up, limping, stiffness, reduced activity, changes in behaviour, and licking or chewing of joints.
If you notice any of these symptoms, it’s essential to seek advice from a veterinarian for a proper diagnosis and appropriate arthritis treatment. Early detection can make a significant difference in managing your dog’s comfort and well-being.
Injections for Dogs With Arthritis

In many cases, some form of medical intervention may be necessary to treat the disease most effectively. This includes intra-articular and subcutaneous injections:
5 Types of Intra-articular Injections
Joint fluid replacement, also known as intra-articular therapy, involves injecting substances directly into the affected joint to reduce inflammation, enhance mobility, and promote healing. Let’s explore some joint fluid replacement options for dogs with arthritis:
1. Stem Cells
Stem cell therapy is a cutting-edge treatment that harnesses your dog’s own stem cells to regenerate damaged joint tissues into healthy ones. These cells can transform themselves into specialised cells, promoting tissue repair and regrowth. Stem cells significantly improve arthritic limbs and reduce pain with minimal disruption to their daily lives. It provides long-lasting relief, making it a top choice for vets treating canine arthritis.
2. PAAG (Polyacrylamide Hydrogel)
PAAG is a non-toxic, biocompatible gel that has been helpful for veterinarians in managing arthritis in dogs. Acting as a joint cushion and lubricant, PAAG promotes the regeneration of tissues, reduces pain, and improves joint function.
3. Hyaluronic Acid (HA)
HA is a naturally occurring substance in the body that works wonders for lubricating joints and reducing inflammation in areas affected by arthritis. Injecting HA provides much-needed lubrication, easing joint pain, and enhancing joint mobility. Think of it as a shock absorber protecting against further damage.
4. Platelet-Rich Plasma (PRP)
PRP therapy for dog arthritis involves drawing a small amount of your dog’s blood, concentrating the platelets, and then injecting the platelet-rich solution into the affected joint. These platelets contain growth factors that stimulate tissue repair and reduce inflammation. PRP encourages joint healing and rejuvenation.
5. Steroids
Corticosteroids, commonly known as steroids, are anti-inflammatory medications that provide rapid relief from arthritis symptoms. While they can be effective in the short term, they are typically used as a last resort due to potential side effects with prolonged use.
4 Types of Subcutaneous Injections

Subcutaneous injection treatments involve injecting medications under the skin rather than directly into the joint. Let’s explore some common subcutaneous injection treatments for dog arthritis:
1. Cartrophen (Pentosan Polysulfate Sodium)
Cartrophen, a disease-modifying osteoarthritis drug (DMOAD), can help to manage arthritis in dogs. In some cases it supports cartilage health, and reduces inflammation. Administered as a series of injections, Cartrophen has shown some results in improving joint function.
2. Osteopen
Osteopen is another DMOAD that targets the root causes of arthritis. It can help to maintain existing, healthy cartilage, and enhances overall joint mobility.
3. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs, like Metacam, are commonly used to manage arthritis pain in dogs. These drugs work similarly to human NSAIDs, reducing inflammation and providing pain relief. However, these only last up to 24 hours and long-term usage should be carefully monitored by a veterinarian to avoid potential side effects.
4. Librela
Librela for dogs is a relatively new medication targeting the nerve growth factor (NGF), a key player in pain signalling. By blocking NGF, Librela can soothe nerves, reduce pain, and improve joint function in dogs with arthritis. Librela may be of help in some cases.
Benefits of Arthritis Injections for Dogs
Now that we’ve explored various injections for dogs with arthritis, here are some key benefits:
- Pain Relief: Intra-articular arthritis injections like Stem Cells, PAAG, HA, and PRP offer effective pain relief for dogs with arthritis. By reducing inflammation and promoting joint repair, these treatments alleviate discomfort, significantly enhancing your dog’s quality of life.
- Improved Mobility: Arthritis can severely limit your dog’s mobility, making everyday activities challenging. Injections designed to enhance joint health and lubrication can enable your dog to move more comfortably and freely.
- Non-Invasive Treatment: Intra-articular injections are minimally invasive and provide a non-surgical alternative for managing arthritis.
- Long-Lasting Effects: Some injections, like stem cell therapy, offer long-lasting relief, reducing the need for frequent treatments and ensuring consistent pain management over an extended period.
- Regenerative Effects: Stem cell therapy and PRP injections promote tissue repair and cartilage regeneration, slowing down arthritis progression and enhancing joint health.
- Convenience: Subcutaneous treatments like Cartrophen and Librela are easy to administer, but may not provide the same benefits as intra-articular injections.

Frequently Asked Questions

How often does my dog need to receive these injections?
The frequency of injections varies based on the type of treatment and the specific needs of your dog. Some treatments, like stem cell therapy, may offer longer-lasting relief, while others might require more frequent administration. Always consult with your veterinarian to determine the best schedule for your pet.
Can these injections be combined with other treatments or medications my dog is currently receiving?
Many of these injections can be used in conjunction with other treatments or medications. However, it’s essential to discuss your dog’s full medical history and current medications with your veterinarian to ensure there are no adverse interactions.
How can weight management help my arthritic dog?
Maintaining a healthy weight can reduce stress on the joints, which can alleviate arthritis pain. Overweight dogs often experience exacerbated arthritis symptoms, so a balanced diet and regular exercise can be beneficial.
