Oncowaf is a website for dog owners with questions about cancer. It is normal for dog owners to remember about a third of the information provided during a consultation, especially when emotions are involved. Since owners will seek additional information when they are ready, they can be referred to a reliable source (www.oncowaf.com). The website also lists ongoing clinical studies, offering additional treatment options for dogs whose conditions are untreatable or for those whose owners have limited financial resources. The website is free, independent, created by veterinarians active in oncology, and is supported by the Belgian Cancer Fund for Animals.
