Luka's trip over the Rainbow Bridge

I 've been putting off the inevitable for months now, waiting for Luka to tell me that it's time...well, now he's telling me. He's restless all night long, incontinent, blind, confused, not eating. I've done so much over the last year to forestall this, from medicines for his hips, to more palatable food, to, well, just giving him bunches of love and a few adventures. The reality is, though, that dogs die, even if they are the best dog in the world, like Luka is. He and I saved each other: I saved him from being the unwanted, older rescue dog with the missing tail and abandonment issues. He saved me from  sadness surrounding so much loss. Loss of my dog Kello, loss of my house, loss of a profitable business. He's been the best dog over the past five years, and the sweetest dog I've ever owned. We've shared big adventures, he's helped me build a new life, and I've depended on his smiles and cuddles and funny personality. Now it's time to let him go, let him leave his failing body and go chase ducks among the stars. Unfortunately I don't have the money to do this right now, and for his sake it really can't wait.  I need everyone's help. It costs between $140 and $200 to have him humanely euthanized and an additional $300 to have him cremated and interred in a wooden box, so I can carry the sweet guy's ashes with me always.

Thanks, everyone, for any help you can give me. It means the world to me.
