Pet Hero Penny is such a happy pup! She is enrolled in a clinical trial for dogs with osteosarcoma (bone cancer). Did you know that gastrointestinal (GI) toxicity can be a common and debilitating consequence of cancer treatment in both human and veterinary patients? The hope with this clinical trial is to help identify potential biomarkers that can be used to assess GI damage following chemotherapy that may assist in developing improved management strategies, reducing the frequency of complications and improve patient quality of life.
