Start the Movement

Catch canine osteoarthritis (OA) at its earliest stages with the innovative OA staging tool.


An Interactive Diagnosis

COAST is an innovative canine OA staging tool designed by a consortium of international experts in veterinary surgery and pain management. With COAST, you can start the conversation about canine OA with pet owners before it sets in, and monitor OA over time. This proactive approach to canine OA can help identify the disease earlier, allowing you to intervene sooner and provide your patients a more comfortable future.

A Standardized Approach to Canine OA Diagnosis

Too often, canine OA goes unnoticed. In its early and mild stages, the signs are so subtle that it’s not always easy to identify that a dog is suffering from canine OA, especially in your clinic.

At home, dogs are more relaxed and more likely to show subtle changes in behavior that their owners can pick up on. It’s important every pet owner knows what to look out for, to help you with early diagnosis and intervention.
