A New Option for Dogs with Arthritis: Introducing Synovan

If your dog receives injections to support their joints, you may have recently noticed a different name on their treatment plan: Synovan.

We wanted to explain why.

At Middle Brighton Vet, we are always looking for ways to help dogs stay comfortable, active, and enjoying life for as long as possible. When a treatment becomes available that we believe offers real additional benefits, we pay attention.

That is why we have recently made the switch from Cartrophen to Synovan.

What is Synovan?

Like Cartrophen, Synovan is an injection designed to support joint health in dogs with arthritis.

Both contain sodium pentosan polysulfate, an ingredient veterinarians have trusted for many years to help protect joints and support mobility. Synovan also contains an additional ingredient called N-acetyl glucosamine (NAG), which helps support cartilage and joint fluid health.

In simple terms, it builds on a treatment we already trust by providing an extra layer of joint support.

Why have we made the switch?

The research comparing Synovan with pentosan alone showed dogs receiving Synovan improved more quickly and achieved better overall results. Dogs in the study showed reduced lameness within the first two weeks and continued improvement throughout the treatment period.

For us, the decision was straightforward. If there is an option that may help our patients feel better sooner and maintain healthier joints over time, we believe it is worth using.

Why it costs a little more

We want to be straightforward about this because you may notice the difference.

Synovan is more expensive than Cartrophen, and that cost is passed on. The reason is simply that Synovan contains two active ingredients instead of one, and the clinical evidence supports a better outcome as a result.

We would not make a switch that increased the cost of your pet's treatment without genuinely believing it was worth it. We believe this one is.

The biggest opportunity is starting early

One of the most common misconceptions about arthritis is that treatment should begin only once a dog is obviously sore or struggling.

In reality, the best time to support joint health is often much earlier. Once significant cartilage damage has occurred, we cannot fully reverse it. Early intervention gives us the best chance of protecting the joints that are still healthy and helping dogs maintain their comfort and mobility for longer.

This is particularly important for breeds that are more likely to develop arthritis, including:

• Labrador Retrievers
• Golden Retrievers
• German Shepherds
• Rottweilers
• Border Collies
• Bernese Mountain Dogs
• Great Danes
• Newfoundlands

Dogs with hip dysplasia, elbow dysplasia, cruciate ligament injuries, previous orthopaedic surgery, or those carrying extra weight can also be at higher risk.

What signs should I watch for?

Arthritis does not always look like limping. Many dogs simply become a slightly slower version of themselves.

You may notice:

• Stiffness after resting
• Hesitation on stairs
• Less enthusiasm for walks
• Reluctance to jump into the car
• Taking longer to get up after lying down

Many owners tell us they did not realise how much their dog had slowed down until treatment started and they saw them moving more comfortably again.

What if my dog is already receiving Cartrophen?

In most cases the transition is straightforward, and we will discuss it with you at your next visit.

Our goal remains exactly the same: helping your dog stay active, comfortable, and able to enjoy the things they love for as long as possible.

Frequently asked questions

Is Synovan the same as Cartrophen?

Both contain sodium pentosan polysulfate, which has been the active ingredient in injectable joint treatment for dogs in Australia for many years. Synovan also contains N-acetyl glucosamine, which Cartrophen does not. The clinical evidence shows better outcomes with the combination.

Is Synovan safe?

Yes. It is made by Ceva Animal Health and is a registered veterinary medicine in Australia. Like Cartrophen, it has a well-established safety profile. It is not cortisone.

Does my dog still need oral joint supplements?

Synovan does not replace all supplements, and a multimodal approach to joint health including appropriate exercise, weight management, and where indicated oral supplements or anti-inflammatories remains best practice. We can discuss what makes sense for your dog at your next visit.

How long do the effects last?

After the initial course of four weekly injections, most dogs benefit from a six-monthly booster to maintain joint health. This is a long-term, lifelong management approach rather than a cure.
