In need of a Name

This is Ruby with Bracken's puppies who will be 1 week old tomorrow, the wee boy in the front is coming to live with his daddy but we are in need of a name for him.

It was a bit touch and go as he would not feed and is the smallest even although he was born first.

So I was thinking Arnie, which means "mountain of strength; eagle
But I am open to suggestions! Does anyone have a better name for him?
