Well, Dan, sure sorry to hear about this.  Them darn little fur balls sure do worm their way into a person's heart.  And when they depart this plane, they leave a huge hole in the heart.
Years back we had a miniature poodle who had no idea she was a dog.  I think she thought she was a people.  Smart, athletic, entertaining, lovable, all she wanted to do was love and please.  When she died at age 15, I decided I could never have a dog as good as that so I never replaced her.  No doubt, we have missed out on a lot of good times.
