Spoiled Rotten (bet he will be)
Moon (Moo-n)
Black Cow
Licorice
Shadow (he'll be Blake's shadow)

How about Blackjack?

Cutie.

Polish word for 'bull' is 'byk' - not a bad name, and easy to say. You could always use boring old English words like 'raven', 'jet', 'ebony' and 'sooty',which I am sure have been done to death. 'Cujo' or 'fang' come to mind as names we called our pets...('fang' was actually a toothless cat we adopted).

I didn't read everyone so I don't know if this has been mentioned, but I think it should be Kaleb - your grandson's name scrambled!
