Clinical Trials

The Lois Bates Acheson Veterinary Teaching Hospital conducts clinical trials in conjunction with research on disease, diagnosis, and treatment of animals. The following are current, open clinical trials that are seeking participants.

Canine Skin Tumor Study

OSU is currently recruiting client-owned dogs affected by, or suspected to be affected by, cutaneous or subcutaneous malignant tumor. This trial evaluates alternative methods of surgical margin assessment to improve accuracy in determining whether a tumor was completely resected. Participants receive free surgery; lab and imaging services are discounted. You may schedule an appointment with the Soft Tissue Surgery service (541-737-4812) for an in-person consultation to see if your pet qualifies for the study. For more information email

   1. Over 8 years old with NO cruciate disease
   2. Under 8 years old WITH cruciate disease
Exam and radiographs will take about one hour and the dog will not be sedated. There is no cost. To participate, contact by August 15, 2014. More Information.

Omental Graft in Miniature and Toy Breed Dogs with Naturally Occurring Radius/Ulna Fractures

Currently recruiting owners of miniature and toy breed dogs with mid-diaphyseal to distal radial fractures who are considering internal fixation treatment for those fractures. The trial will determine the efficacy of an omental graft in addition to a plate and screw fixator. Surgery and other costs are provided by an American College of Veterinary Surgery grant at no cost to owners. Read more.

Canine Shoulder Injury Study
