Not for the multiple posting -- that's nothing. I'm so sorry to hear that you're about to lose your dog. I'm not going to post a silly story here, but instead give you a little advice. :)
I know this is probably too soon to start thinking about this, but when Finnegan is gone, the greatest memorial you can give him will be to take in another dog -- preferably one whom you rescue, either from a local animal shelter or through one of the many breed rescue organizations on the 'net. There's a breed rescue organization for cocker spaniels, too.
Another dog will never replace Finnegan in your heart, but he/she will help to ease the loss for you.
And, if you want a suggestion for a name for your next dog...
For a male: "Finnegan Begin Again" (call him "Finnegan" for short)
For a female: "Gina, I began Finnegan" (which is an anagram of "Finnegan Begin Again" -- call her "Gina" for short).
Good luck to you, Arikka.
