Hi and a big welcome from the "ROCK" Newfoundland, it's better know as the Rock. LOL
I'm so sorry for your loss, and yes if he was a cuddlier he may very well be a hard act to follow.
But ya know they are all as unique in their own way, so I'm sure you'll be happy with a new one no matter what the personality.
Besides you wouldn't want to replace him, could never, just love another the same but different.
I am very close to all 26 of my pet chins, and have to try not to get too attached to kits or I have to keep them.

So have you though about a colour you'd like to have?
