Learning one's cherished dog has cancer is a common experience among dog owners today. Upon diagnosis, veterinarians may suggest surgery or chemotherapy. But, our dog's cancer was too widespread for surgery, and the harshness of chemotherapy seemed inappropriate for this gentle-natured golden. Instead, we chose to celebrate the life and spirit of our beloved pet each remaining day left with him. What happened next is an adventurous true story of love and courage. Last Summer with Oscar is a narrative case study about a 9-year old Golden Retriever's response to cancer. While my husband and I came to grips with his diagnosis, Oscar made an amazing discovery. Nestled among a patch of young trees were Slippery Elm seedlings, and eating them became his choice of treatment. Oscar's determination to live enabled him to return to this patch to eat the leaves, thereby regaining his strength for continued walks with his littermate, Winston. Oscar, the teacher, found new ways to communicate with me, his student. Together, we explored little-known remedies for cancer. The goodness of the journey elicited kindness and goodness from others. Last Summer with Oscar is filled with anecdotes that inspire love and a true belief in the potential of humanity.
