I've lost 2 hounds to cancer: Chloe with Osteo and Fritz to Lymphoma. When he was first diagnosed I opted for chemo for him. It worked and he was in remission for a year. It then came back and the poor guy was so sick that I had to have him PTS. The oncologist assured me that it couldn't be cured. Fritz was my first ever hound - my heartdog - I miss him even today.
