his idea just came up in the Nexus chat. Simplest of mods.. XBitu wanted a dog follower and I said a have a few house mods that have them. 
But then I realised I wanted a dog too, so I separated the dog from the rest of the (house) mod, Holmwood.

Originally he was Blade, a vampire hunter dog, but now he is Doge, an Altmer's best friend.
Can be found in Riverwood, outside at the camp site, he will follow you once you activate him. 
Due to the custom dialogue there is no "Want to come with me?" thing.

If you want him to stay ANYWHERE and treat it as home, just use My Home Is Your Home
