I hope for the best for Fluffy and you. Thank you for this post...my Lucy (almost 12) and I have been going through this situation ourselves since last Sept and this thread has made me feel better about the decisions I have made not to aggressively treat her suspected lung cancer. We went the chemo route with our first boxer, Bailey, and I have no regrets about that...was right for that situation, but I truley believe had we tried chemo or radiation with Lucy, she might be gone by this point. She, like your Fluffy, has a lot of good days in her. The biggest problem I see is she can not keep herself from trying to keep up with the younger Fred (our male boxer, now 4). I hate to see that saddness in her face when she seems to realize there is something wrong. Thanks againg for sharing your experience.
