Bring a dog home and convince them to adopt. Dorthe adopted a rabbit, Braggen brought Meeko home as a follower, Dorthe's reaction was, stupid dog. Fine Braggen wandered all over the house with Meeko, the kid never warmed up to him. Braggen told Meeko to wait where Dorthe was sitting, left to do other things in Skyrim. Meeko stayed a long time, came back Dorthe wants a dog, fancy that.

Meeko now has a home and Dorthe has two pets.
When my second character eventually starts house building she will be trying to get a very cute husky adopted.
