I'm so sorry you're going through this Jagcatfan.
I know how difficult it is.
Remember that Snoozie doesn't know about cancer. Dogs tend to be hopeful creatures--if they aren't feeling well, they hunker down and wait to get better. Snoozie doesn't worry about dying because she's too busy living.
So how does Snoozie seem to be feeling otherwise? Is she still happy to see you? Still playing? Seems to be comfortable? If her good moments outweigh her bad moments, then she's still busy living
and it isn't time, yet.
When it finally comes down to that last decision, you'll be there for her, to help ease her way. She'll feel your love and strength to the end and it's the best gift she could ask for.
Time enough to mourn afterward--till then, rejoice in each good moment.
You're in my thoughts and prayers, Jagcatfan. We're here for you. Please keep us posted.
