Thank you, everyone, for your condolences. I know my little boy is running and playing in Heaven. He has a brother with him, so he's not alone. And I'm sure he's with my other pets, probably harrassing my other cats and rabbits.
My neighbor still has one of Nugget's other litter mates, and I've been getting my puppy fix from him for now. It really helps.
And I've been trying to focus on the cute things Nugget did. We have a 1/2 mile walk to our mailbox. Charlie (my other dog), Nugget, and I would take our daily walk down to the mailbox to get the mail. I'm not quite sure how it started, but Nugget would sit and wait until I gave him an envelope to carry back to our house. He would carry it all the way back, and would act so proud as he did it.
Just thought I'd share something positive. -Robin
