Help us name our darling boy

We just rescued this sweet thing a few days ago and are struggling to find a name we're happy with.

He was found running around a UK motorway for days before being taken to the rescue & we found him 43 days later.

He's 34kg, incredibly cuddly & has the waggiest tail ever. We travel & hike a lot too if that helps. A name that reflects his gentle personality whilst matching his stature would be great!
