I was so sorry to learn of your little dog's illness when you replied to my post regarding the loss of our beloved Schnoodle. You mentioned having had your pet for 14 years. That's how long we had Joey. (My eyes are tearing up just writing this.) He's been gone over a week now & I still think I see him every so often such as when I turn a corner in our home. Last night I dreamt he curled up alongside my head in bed.
Perhaps you're already familiar with this. But, just in case not, here's a link to my favorite grief-&-loss-related article in PC's archives:
What My Dog Taught Me about Grief and Loss
My best wishes to you & your family...
