Children/ YA Fantasy: book about a boy and a dragon based in the real world, from an Irish or Scottish author. The boy and the dragon have a bond and the dragon gives him a scale as a connection.

I read this maybe 6 or 7 years ago and I can’t for the life of me remember the title. It may be a series and it starts on an island by the sea where a boy finds a big rock that looks like a dragon. It turns out it actually was and they become friends.

Eragon is what I first thought of too.
