Anne Marie Messano Petrie and her husband Geoff Petrie are grieving the loss of their beloved golden retriever Winston, who passed away last year from hemangiosarcoma (HSA). A particularly aggressive canine cancer, HSA is known as a silent killer. Although some treatments are available to extend a dog’s life, it is rarely curable. In the midst of their loss, they have established Winston’s Golden Promise, a fund in support of UC Davis’ canine cancer research.
