By delivering microscopic radioparticles (called tin-117m), Synovetin OA is designed to address inflammation inside the joint, and reduce the harmful cells that cause arthritis to develop and get worse over time. It’s similar to the medical radiotherapy that is routinely used to safely and effectively treat numerous medical conditions in people.
Other dog arthritis treatments primarily work to mask pain symptoms but don’t adequately address the cause of the disease itself the way Synovetin OA can. And, because Synovetin OA works only inside the arthritic joint, it does not spread throughout the body like other treatments do, which can cause side effects.
It’s a simple, safe, fast arthritis injection, after which your dog can go home with you the same day. And there’s no need for the inconvenient restraint that comes with invasive procedures.

The active ingredient in Synovetin OA is only present in the body for a few weeks but the effect on inflammation and the resulting joint pain is very long-lasting—up to 1 full year, depending on the severity of arthritis. Plus, extensive safety studies and real-world use of Synovetin OA showed it does not cause systemic adverse effects and is safe for your dog, other pets, and your family.
Patients treated in-house will receive $150 off each joint treated.

Before Dr. Hays’/Animal Imaging’s Synovetin treatment, my Roxanne Dolores only wanted to lie down and struggled to get up. I knew walking and even sitting still was painful for her. No more running or hopping or crawling up into MY chair for fun. She has a great sense of humor, but her eyes just said “pain” and “bored.” Got her expensive knee surgery, physical therapy, massage and ice/heat regularly — but even those didn’t work well enough, and now she just had a limp on top of everything. STILL bad arthritis. I thought I’d lost her, but waited for the injections to decide. It worked this time – she RUNS everywhere now. Twists, hops, races into her home to be first for dinner. Loves twisting and running away from me again when I call her, like the old days. THANK YOU GUYS!!
