Brothers. They were 3 puppies, their sister Roo was sick when she was born and stopped growing when she was about 4 months. They live together and she rules the kennel. Tiny dog with huuuge ego.
That's a shame, but I'm glad Roo is still leading a happy, loving, and healthy life! ☺️ Tiny dogs do have a certain reputation for ego though, there's a whole syndrome named after them!
